Fender P-Bass Pickup Height: Measure and Balance

Getting Fender P-Bass pickup height right starts with identifying the pickup actually installed, not with memorising one number. Fender publishes its bass pickup references by pickup type, measured with the string held at the last fret. Identify the hardware, measure the clearance that applies, then change one thing at a time.

Quick answer: Tune the bass and finish any relief and action work first. Hold the outer string at the last fret and measure from the top of the pole piece to the underside of the string. Fender's starting reference for a vintage-style or Noiseless Precision pickup is 8/64" (3.2 mm) on the bass side and 6/64" (2.4 mm) on the treble side; for a standard P pickup it is 7/64" (2.8 mm) and 5/64" (2.0 mm). Both are starting points for that measuring method, not targets for every Precision Bass. Then balance the strings by ear through a clean amp.

This page changed on September 16, 2026. It previously presented 3.2 mm / 2.4 mm as a universal P-Bass specification, listed genre-based settings as if they were factory figures, and quoted a screw-turn-to-millimetre conversion that thread pitch does not support. The revised guide scopes every number to a source, a measuring fret and a contact point, and replaces presets with a repeatable comparison you run on your own bass.

P-Bass pickup height specs: which reference applies

Fender's bass setup instructions hold the outer strings at the last fret and measure from the bottom of the string to the top of the pole piece. The same article groups its starting references by pickup type rather than by model name:

Fender pickup category	Bass side (E string)	Treble side (G string)	Measuring method
Vintage style	8/64" (3.2 mm)	6/64" (2.4 mm)	Outer strings held at last fret; pole top to string underside
Noiseless Series	8/64" (3.2 mm)	6/64" (2.4 mm)	Same method
Standard "J" or "P"	7/64" (2.8 mm)	5/64" (2.0 mm)	Same method
Special Design Humbuckers	7/64" (2.8 mm)	5/64" (2.0 mm)	Same method

Three cautions belong with that table:

• Fender calls these minimum specifications and a guide, not hard rules. The same article notes that the distance varies with the pickup's magnetic pull, and that larger gauges and five-string basses need wider clearance for the string's vibration.
• Fender's pages do not all agree. The older factory setup specifications page lists the standard bass row as 6/64" bass side and 5/64" treble side. Where the two differ, this guide follows the bass-specific pickup-type table above. Record which source and method you used.
• A model name does not identify the pickup category. American Standard, Player, Vintera, American Professional and Squier Precision Basses have shipped with different pickups. Check the model page or your paperwork; a replacement pickup follows its own maker's reference instead.

The free pickup-height calculator can compare your measured gap with a stored target. Check which pickup category its target represents before treating the result as a verdict — a calculator cannot see which pickup is installed.

The split-coil layout: what you are actually measuring

Two halves, two string pairs

The Precision pickup is a split-coil: one coil section sits under the E and A strings, the other under the D and G strings, offset along the scale. Each half has its own pole pieces and its own end of the height adjustment — you are balancing two small pickups, not centering one big one.

Because the halves are wired as a hum-cancelling pair, there is no selector to isolate them. Your balance check is string against string: E against A on one half, D against G on the other, and the bass side against the treble side overall.

Pickup height is not the number you measure

The clearance you measure — pole top to string underside — and the pickup's physical position are two ends of the same relationship, moving in opposite directions:

• A higher pickup sits closer to the strings, so the measured clearance is smaller.
• A lower pickup sits further away, so the clearance is larger.

This sounds trivial until a table and a screwdriver meet. Fender's reference numbers are clearances: 8/64" on the bass side means a larger gap, so the bass half sits relatively further from its strings than the treble half. If you think in pickup position while reading a clearance table, you will adjust in the wrong direction. Pick one convention — this guide measures clearance — and write your readings down that way.

Schematic, not a measured drawing. The clearance arrows show the contact points Fender specifies: outer strings held at the last fret, measured over the pole piece.

When the poles are not visible

Some replacement pickups hide the pole pieces under a closed cover, so pole-to-string clearance cannot be measured directly. Record cover top to string underside instead, with the held fret and exact spot noted — and label it as a cover measurement. Do not subtract an assumed cover thickness: covers and hidden pole positions vary, and a guessed correction invents precision you do not have. Ask the pickup maker which reference and target apply.

The same route covers other variations this page cannot number for you:

Instrument or pickup	Route
Replacement pickup (any make)	Use the maker's own method and target; do not borrow Fender's row
Covered poles	Label a cover-to-string measurement; confirm the reference with the maker
Precision/Jazz (P/J) set	Treat the P and J units separately; the Jazz Bass pickup-height guide covers the J side's own reference row
Five-string Precision	Same method per string; Fender notes heavier gauges and five-strings need wider clearance — no fixed universal increment exists
Unidentified pickup	Identify it first (paperwork, maker photos, model page); measure and record your baseline while you do

Before you adjust anything

Pickup clearance is measured against the string's position, so everything that moves the string has to be settled first.

Tune, and use the strings you intend to play

Measure with the bass tuned to your normal pitch — the clearance figures assume playing tension. Use the string set you actually play. A healthy older set does not need replacing just because you are measuring, but a damaged or corroded set will mislead the checks that follow. If you are changing gauge or construction anyway, fit the new set before measuring and let it settle until the tuning repeats; our Precision Bass string guide covers gauge and fit separately. Fender's own note applies here: larger gauges vibrate wider and need more clearance, so do not carry a light-gauge setting over to a heavy set unexamined.

Settle relief and action first — with the right measuring frets

The clearance between pole and string depends on where the string sits, which relief and action set. Fender's bass reference methods, quoted with their measuring points:

• Relief: tuned instrument, capo at the first fret, lowest string held at the last fret, gap measured from string underside to the eighth fret crown. For a 9.5"–12" radius the reference is .012" (0.3 mm).
• Action: capo off, open tuned strings, measured from string underside to the seventeenth fret crown. For a 9.5"–12" radius the references are 6/64" (2.4 mm) bass side and 5/64" (2.0 mm) treble side.

This page previously quoted a twelfth-fret action figure alongside these pickup numbers. Do not mix methods: a measurement taken at the twelfth fret is a different number from Fender's seventeenth-fret reference, and neither converts into the other. If your string action needs work, the Precision Bass string-height guide and the complete P-Bass setup guide follow Fender's seventeenth-fret method.

Set one clean amp reference and identify the pickup

Choose one clean amplifier setting and leave its gain and EQ untouched for the whole comparison. Note the bass's volume and tone control positions and keep them fixed. If the bass has active electronics, check the battery and pick a repeatable neutral setting — a weak battery or a changed gain stage can mimic a pickup problem.

Then confirm which pickup category you have. "Precision Bass" on the headstock does not tell you whether the split-coil is vintage-style, standard, Noiseless or a replacement. Use the model page, your paperwork or the maker's identification before choosing a reference row.

Tools that make the measurement honest

You need a chromatic tuner, a ruler or action gauge with legible 64ths or half-millimetre graduations, good lighting, and a screwdriver that fits the actual screw head. Support the bass securely and keep the ruler from pressing the string down or scratching the finish.

Use one unit throughout your record. For orientation only, 1/64" is about 0.4 mm — the conversions in the reference table preserve Fender's rounded equivalents. Record what your gauge can actually resolve rather than claiming hundredths of a millimetre from a coarse ruler.

Measure, adjust and compare

Step 1: Record the baseline

Hold the E string at the last fret and measure the clearance over its pole piece. Repeat for the G string. Write both numbers down with the date, string set and tuner reference. If the A and D strings sound uneven, measure them too — but Fender's reference rows are read from the outer strings. Measure each gap twice; if readings disagree, fix the held fret, ruler angle or pickup rock before trusting either.

Step 2: Identify what the screw actually moves

Look directly at the screw head when describing clockwise or counterclockwise. The traditional Precision arrangement mounts the pickup into the body against compressible foam or springs: Fender's American Professional II Precision Bass service manual lists a wood screw threading into the body and a neoprene pad beneath the pickup. On that arrangement, tightening the screw pulls the pickup down — the gap grows — and loosening lets the support push it up. A pickup suspended from a pickguard or ring works the other way round.

Confirmed mount	Clockwise (viewed at the screw head)	Counterclockwise
Screwed into the body with foam or springs beneath	Lowers pickup; clearance increases	Allows pickup to rise; clearance decreases
Suspended from a pickguard or ring	Raises pickup; clearance decreases	Lowers pickup; clearance increases
Unidentified, altered or stuck assembly	Stop and identify it	Stop and identify it

A screw fixing a cover or pickguard is not necessarily a height screw. If the pickup does not follow a small turn, stop — compressed support, binding or limited travel needs inspection, not more force.

Step 3: Make one small change

Pick the side connected to your symptom. If the D and G strings overpower the E and A, a small treble-side change is more informative than moving both halves at once.

1. Note the current clearance and the symptom.
2. Turn the confirmed height screw a small amount, such as a quarter-turn, watching which way the pickup moves.
3. Remeasure both sides of that half with the same contact points.
4. Retune if needed and play the comparison phrase (below).
5. Keep or reverse the change according to the result, then write it down.

A quarter-turn is a convenient small step, not a guaranteed millimetre movement. This page once claimed a fixed turn fraction equals 0.2–0.3 mm; thread pitch, support compression and pickup tilt make that conversion unreliable. Measure the actual change instead of predicting it.

Step 4: Compare the strings through the same clean signal

A listening comparison only means something if everything else stays fixed. Keep the instrument controls, the clean amp setting, your picking position and the test phrase identical between trials. A useful phrase includes an open low note, a mid-register line and something at your hardest normal attack.

• Play each string with the same attack and compare perceived volume — E against A, D against G, then bass side against treble side.
• Play your hardest normal strokes and listen for the string striking the cover or pole.
• Sustain low notes and listen for warble or pitch instability.

Record what you actually hear in plain words — "A string now matches E; no contact slapping open E" is useful. "Sounds better" is not.

Step 5: Check clearance as played, then decide

Static numbers do not overrule contact. If the string touches the pickup during your hardest normal playing, the clearance is too small for your attack regardless of the table. If a trial made things worse, return to the recorded baseline — an unchanged but documented setup is a valid outcome, not a failed one.

There are no genre presets here. Slap, pick and fingerstyle players attack the string differently, and the right clearance is the one that survives your own hardest playing while giving the balance you want. Start from the applicable Fender row, run the comparison, and keep what works.

Symptoms, checks and stopping points

These are checks to narrow a problem, not proof that every symptom has one cause.

Observation	First controlled check	If it persists
One string noticeably quieter or louder	Repeat the measurement over its pole with the same attack; check pickup tilt	Identify the pickup and consult its maker before touching individual poles
Sustained low notes warble or pitch wavers	Record the gap; make a small lowering trial on that side and repeat the note	Check strings, relief and the wider setup rather than assuming magnetic pull
String strikes the cover or pole when played hard	Measure during your hardest normal playing; increase clearance in small steps	Re-examine attack, action and string gauge — clearance is one of several inputs
Overall weak or distorted output	Check battery (if active), cable, controls and amp gain before moving the pickup	Investigate electronics; height is not the only cause of a weak signal
Harsh, compressed response	Record the gap; try a small lowering trial and repeat the comparison phrase	Revisit amp EQ and string condition before chasing smaller gaps
Pickup sinks, rocks, or screws no longer move it	Stop turning; identify the support arrangement and screw engagement	Have collapsed foam, springs, threads or fit inspected before further adjustment

Stop conditions deserve emphasis. If a screw spins without moving the pickup, the support may have collapsed or the thread stripped. If the pickup will not rise, something binds. Neither is fixed by turning harder — hand a stuck assembly to a technician with your measurement record attached.

Frequently asked questions

What is the correct Fender P-Bass pickup height?

Fender publishes starting references by pickup type, measured with the outer strings held at the last fret from pole top to string underside: 8/64" (3.2 mm) bass side and 6/64" (2.4 mm) treble side for vintage-style and Noiseless pickups, 7/64" (2.8 mm) and 5/64" (2.0 mm) for standard P/J pickups. Fender describes these as minimum specifications and a guide, not hard rules. Identify your pickup before choosing a row.

Where do you measure P-Bass pickup height?

Hold the outer string (E for the bass side, G for the treble side) down at the last fret and measure from the top of the pole piece to the underside of the string, directly over the pole. Measure with the bass tuned to playing pitch, after relief and action are settled.

Which way do P-Bass pickup screws turn?

It depends on the mount. On the traditional body-mounted arrangement — screw threading into the body with foam or springs beneath — tightening (clockwise at the screw head) lowers the pickup and increases the clearance; loosening lets it rise. A pickguard- or ring-suspended pickup works in reverse. Confirm the mount and watch the pickup move before committing to a direction.

Should the bass side be closer than the treble side?

Fender's reference rows give the bass side a larger clearance — a bigger pole-to-string gap — than the treble side. In pickup-position terms, the bass half sits slightly lower relative to its strings. Remember that clearance and pickup height move in opposite directions before turning anything.

Does a quarter-turn move the pickup 0.2 mm?

No. Thread pitch, support compression and pickup tilt all change how far a turn moves the pickup, and compressed foam moves non-linearly. Use a small turn as a trial, then remeasure both sides with the same contact points.

What pickup height is best for slap, pick or fingerstyle?

There is no verified universal number per playing style. Start from the reference row for your pickup, then run a fixed comparison: same controls, same clean amp setting, same phrase and picking position. The right clearance survives your hardest normal attack without string contact and gives the string balance you want.

Do heavier strings or a five-string need different clearance?

Fender's bass setup instructions note that larger gauges and five-string basses need wider clearance for the string's vibration, without specifying a fixed increment. Remeasure after any string or tuning change and check clearance during your hardest playing rather than applying an assumed offset.

Can pickup height cause warbling or affect tuning stability?

A magnetic pickup very close to the string can influence its vibration, which can show up as warble or pitch instability on sustained notes — most noticeably on the heavier strings. Make a small lowering trial and retest. If it persists, check strings, relief and the wider setup instead of assuming the pickup is the only cause.

Does this apply to a Squier Precision Bass or a replacement pickup?

The measuring method transfers; the numbers may not. Fender's table covers Fender pickup categories. Identify the installed pickup — including any replacement — and use its maker's reference where one exists. Record your own baseline while you identify it.

How often should I check P-Bass pickup height?

Recheck after a string gauge or construction change, a tuning change, relief or action work, or a new symptom. A stable instrument does not need re-measurement on a fixed calendar.

Keep a clearance you can reproduce

P-Bass pickup height is a two-minute measurement with a ten-minute comparison attached. Identify the pickup, use the Fender reference row that matches it, keep the method with the number, and change one side at a time. Write down your final clearances and what you heard — that record is worth more than any universal spec, including the ones on this page.
