If you're talking about the bass on the amp, which I assume you are cuz I'm pretty certain you play mostly a P, I honestly don't know how that's possible. I never tried it, but there ain't no way that's happening on my amp. If I push the bass past 1:00 it starts getting boomy as all hell. I've played through a lot of Ampegs too, and almost always have to dial back the bass.
I believe you, but I think I'm missing something somehow.
This is from a while ago, but it's the only vid I have of me playing through an Ampeg. I used to keep my Bongo set pretty flat, and I know I had that amp set flat or less than. I can't imagine what the bass would sound like if I turned the lows on that amp to 10.
And thanks, cuz I now have a reason to post this video

. Which I like, and never really get a good reason to post. I only played with this band for about a year.
