The BASS TEN LONG is a ten-position EQ control featuring eight hi-cut / mid-cut resonance filters, plus a "virtual tone pot" loading circuit and true bypass. Maximum capacitance: .100µF.
The B-10-L is compatible with passive high-impedance basses with two "volume-tone" knobs (P-Bass), or four "volume-tone-volume-tone" knobs (RIC). Use one B-10 per volume control.
A "ToneStyler X" is essentially a "re-scaled" Bass TEN LONG with the same split-shaft, and now using the traditional .047µF cap value in the lowest #1 anti-clockwise position... vs the deeper .100µF cap, as used in the BASS TEN.
If you are looking for the DUO SIX, the DUO SIX is currently out of production, and will likely not see a return in the near future, if ever. Grab a BASS TEN LONG or X LONG instead. It can be wired for a Jazz Bass®, it will just require using a Volume-Blend-Tone configuration rather than the traditional V-V-T.
*The Bass Ten Long is NOT FOR "Volume-Volume-Tone", J-Bass, or T-Bird (need to use a Volume-Blend-Tone Configuration instead)*
*Does NOT FIT Epiphone 18-coarse-spline metric push-on knobs.*
100% passive analog circuity - no batteries - zero noise! Made in U.S.A.
24-fine-spline split-shaft tip fits USA push-on knobs, plus 6mm & 1/4” set-screw knobs. 3/8”-32 dia. x 1/2” length USA bushing mounts through all surfaces up to 3/8” thick. Compact polymer module: 0.875" dia.x 0.8125" behind-panel depth.
