I bought one of these to push the gain up some more on my Fender Blues Jr. Thought I'd try it on bass and... ...holy mother of God! Afterburner Overdrive - Jet City Amplification I will be making a video of it this week
I had one a while ago and wasn't impressed at all. The pots had no range, boost was useless, and it didn't have much character to my ear. I returned it pretty quickly. Maybe I got a dud? I'd like to hear what you're hearing.
On bass, the boost is useless... I agree 100% there But something to keep in mind with this pedal though is that it works best when pushing the front end of a tube amp. To be honest, I haven't tried it on a solid state amp for bass or guitar yet, but I expect it won't sound as good. What kind of amp were you using? Also, I have 1x15 and 1x12 cabs with a 3 band fully parametric EQ, so I've got an extremely full range. I can at least say that for guitar, it's far from dull: Jet City Afterburner Overdrive - Lead Channel Demo - YouTube Anyway, I'll get a video posted this week.
