i have toyed with the idea of adding a more comprehensive eq, but i really wanted to avoid adding pedals to make the volume pedal work, i.e.:buffer, eq, etc......
how does having a signal with a little more oomph effect your fuzz? when i changed basses (still passive, but a hotter signal, it made my fuzz pedal sound like a wet fart.)
The MXR preamp has an input and output gain control. So if one bass is passive and the other is active, I can up the input gain so the levels match into the Fuzz unit.
