Full disclosure: I started out as a guitard who mainly used his volume knob to go from clean to dirty sounds. While I try to do the same on bass, I find it a lot tougher to reach down and make quick changes on-the-fly on my P-bass. I tend to play with a decent amount of gain (VT Bass into an Ampeg SVP-CL just as pre's) so I'm looking to have a switch to stomp on which rolls off some volume/gain for a clean tone when engaged (and full distortion/gain when disengaged). Kind of a reverse distortion/volume "down" pedal if you will. Basically, I'm wondering if there's any passive and volume "stomp" pedals (or schematics/reputable builders) out there. Not looking for anything aside from the standard P-bass guts in a stomp-able form really. Not looking to use a traditional volume pedal as my foot isn't sensitive or steady enough to utilize this method properly. Tone controls (passive, ala the P-bass) would be appreciated but not as necessary. Any advice?? Thanks in advance for your help!
