How to Adjust Pickup Height on a Shark Guitar

Pickup height is one of the most overlooked adjustments on an electric guitar. The distance between your strings and your pickups shapes output, dynamics, and character. All it takes is a hex key, a small ruler, and a few minutes of listening. The basics below apply to any electric guitar. The last section shows how the adjustment works on Shark Pickup Modules.

Why Pickup Height Matters

A pickup reads string vibration through a magnetic field, and distance decides how much of that vibration it captures.

Closer to the strings: stronger output, thicker midrange, more aggressive attack. Too close, though, and the magnets start pulling on the strings. That chokes sustain and can add a warbling, out-of-tune quality on the upper frets.

Farther from the strings: cleaner, airier, more dynamic range. Too far, and the signal weakens and the sound thins out.

The goal is the window in between: close enough for a full, confident signal, far enough that the strings vibrate freely.

Before You Begin

Pickup height is the last step of a setup. If you plan to change your string height (action), do that first: it changes the exact gap you are about to measure. Tune to pitch before you measure.

What You Need

• Your Shark Guitar, tuned to pitch
• No. 3 Hex Key (provided with your Shark Guitar, any standard No. 3 hex key works)
• A small ruler with millimeter markings
• Your amp, set clean, at a comfortable volume

How to Measure

Hold the low E string down at the last fret and measure from the top of the bass side pole piece (the metal dots under the strings) to the bottom of the string. Then hold the high E string down at the last fret and measure the treble side the same way. If your pickup has no visible pole pieces, measure to the top of the cover.

Fretting at the last fret puts the string at its closest playing position to the pickup. That is the distance that matters.

Starting Points

These are widely used starting values for both the neck and the bridge pickup, measured at the last fret as described above. Treat them as starting points, not rules.

• Humbuckers: about 2.4 mm (3/32") on the bass side, about 1.6 mm (1/16") on the treble side
• Single coils: about 3.2 mm (1/8") on the bass side, about 2.4 mm (3/32") on the treble side
• Active pickups: these can sit closer, around 1.6 mm (1/16") on both sides, because their magnetic pull is very low

Strings swing wider over the neck position, so at the same height the neck pickup usually sounds louder than the bridge pickup. If it does, lower the neck pickup a little at a time until the two match in volume.

Adjusting Height on Shark Pickup Modules

Every Shark Pickup Module carries its own height mechanism: two spring-loaded height screws on the back of the module, one for the bass side and one for the treble side. They take the same No. 3 Hex Key. Because the mechanism is on the module itself, the setting stays with the pickup: swap modules, and each one comes back at the height you set.

1. Find the height screws. The two height screws are on the back of the module. They are the only screws you touch for this adjustment.

2. Adjust in quarter turns. Turn a screw a quarter turn, then check the gap at the last fret again. Fractions of a millimeter are audible, so small steps work best. The springs hold the setting wherever you stop.

3. Do not loosen a screw too far. Loosened past its limit, a height screw can come out of its thread and fall out of the module. If a screw suddenly turns with no resistance, that is the limit: turn it back in.

4. Play and compare. Plug in, keep the amp clean, and switch between pickup positions, listening for an even volume. A warbling, out-of-tune quality high up the neck means the pickup is too close: lower it. A thin, weak sound means it is too far: raise it.

There is no single correct pickup height. There is the height that makes your pickups sound right to you. Take your time and trust your ears.
