I just recently bought a used Thunderbass ET5. It is THE nicest bass i have EVER played by far. This may sounds ridiculous to try and use on a bass that has such a remarkable clean tone, but normally i play with a Boss ODB bass overdrive out of an old late '70's Ibanez bass. When using the same preamp config with the Pedulla, I get a huge volume gain decrease, as well as overall tone (especially the lows) cut. Is this because this $100 pedal is not designed to play a $3000 bass or active circuitry? I really love the bass, but i MUST have overdrive as I use it %95 of the time dirty. Any info on this would be GREATLY appreciated.
