Could probably have asked this in basses or pups, but as distortion with pedals (and amp gain) is my issue I´ll try here. Sorry for the long write up. I have a Fender Modern Player Jazz, with relatively hot passive humbuckers. Run into a MXR bass overdrive and an Ampeg PF350. When turning up gain I can get a quite heavy distortion from the amp. It seemed way to "on and of" in the beginning (no gradual increase), but it appears to have settled down, and in a band setting sounds good now. (Although a class D amp shouldn´t bed in??). Tried a passive Yamaha, with single coil pups, and couldn´t get any distortion at all. Even with gain at full. Noticeably quieter, so very different pups. With the MXR bass overdrive and my Fender I get a lot of distortion even at the lowest drive setting. With the Yamaha I can go from virtually no overdrive, to lots of overdrive. Which is what I want. I love how the fender sound clean. But I cant seem to get the soft tiny bit of overdrive I want from it. Could there be something wrong? Or is there something I could do to remedy my issues? Rolling of volume on my bass, almost all the way, kind of helps, but not a good solution I think. I´ve got a VT Bass pedal on its way, to hopefully get my soft mellow over driven sound, but now I´m skeptical something is up with my Fender. Any one had similar issues?
