What can you guys tell me about the overdrive circuit on the Rumble 100? I've got both knobs turned all the way up, and so far I get a lot more volume, but never any distortion. Do I need to turn up the input gain and turn down the master to get distortion at low volume?
Pics of your settings?
Gopher, see the Rumble Talks link on Fender Rumble Overdrive, Adjust Gain, Drive and Level to Taste. I will add, in your case, don't be too conservative with your EQ on the amp and on the bass, as well. I know I like to have such low EQ and low bass volume for clean tones with the availability of quick manual boosts onstage but, for some gritty distortion add more of the EQ frequency(s) you want to a very strong input signal.
