Gain and Volume and maybe mixed with some op amp staging, but mostly the gain/volume. I would like to add a nice variance of different warmth>grit>od to my signal but retain, for the most part my signal tone. Basically the gain set out of any of the tube pedals, but try to have a variety of different breakup. Really only two knobs, I wouldn't even care for a stomp button but I guess if you used it for OD or soloing that would be nice to have.
Honestly whether people know it or not, I bet a lot of them looking for this tube sound, want this. I know a lot of folks buying preamp pedals and preamps just to get the tube break up and "warmth", and don't really care too much about what the EQ brings to the table. I love the way my basses sound, and the few preamps I have are all I need, but if I could have a pedal, box whatever, that allowed me to control the breakup, and type of breakup to add to my tone, that would be awesome
You mean a bit like the bias control in the newer versions of the BK Butler Tube Driver?
