How can i modify and old Boss SD-1 to better suit bass and is it possible to do it by just changing the Tone knob.

Right now i lose so much of my bottom end which sucks for my bass.


Washburn RB2500 (5 String)
Yamaha BB400 Fretless (1981)
Carlo Giordano 3/4 Upright (White)
Cort Action 4 (Stereo-fied)
Orange Bass Terror 500
Orange 1x15 Cab
Boss GT-6 Bass Multi-effects
I'll pitch in..

Replace C3 with .15uf

Who's next?

If your EQ looks like this your audience will look like this
Increase the input capacitor, definitely. Also, increasing the value of the .01 cap in the feedback loop of the second op-amp would help give you more bass.
