Will it fit
my guitar?
Q15 is a right-handed 25.5-inch Strat-style bolt-on replacement neck. It has a 55.6 mm ±0.5 mm heel, 10 mm tuner holes, a headstock-adjustable truss rod and undrilled heel mounting holes. Align the holes to the body being fitted. Check your guitar’s scale, pocket, bridge position and mounting pattern before installation.

Fit the heel to your guitar.
The heel is supplied without mounting holes so they can be aligned to the body being fitted. Check the neck pocket, bridge position and mounting pattern, then transfer the hole locations and drill the heel to match. A guitar technician can help with fitting and setup.

How does the Q15 layout compare with a full 24-TET fretboard?

Are the standard fret positions retained?
Yes. Q15 keeps all 21 standard 12-TET positions and adds 15 quarter-tone positions between standard frets 0 and 15, at 0.5 through 14.5.
Who is Q15 for?
Anyone curious about exploring quarter-tone positions, from first-time players to experienced microtonal musicians.
What should I check before fitting?
Check your guitar’s scale length, neck pocket and heel dimensions, mounting pattern, and tuner requirements. Strat-style guitars vary; send us the model and measurements if you’d like help checking fit.
