Hi! I was thinking of adding an onboard preamp to a bass I have that is, well, less powerful then the others I have. I don't really need a bass, mid or treble knob, just more power, but flat EQ-wise. I know there's a little onboard preamp available on the market that does that, I think the price tag is around 65$, but I can't seem to find it or remember who makes it. Any idea? Any other suggestions for what I need?
