A $35.00 guitar amplifier. I went to the Pawn Shop trying to be frugal instead of buying new. Don’t know anything about amplifier brands as I’m a newbie bassist so hubby said he heard of Peavy, that’s what I bought. Something’s wrong with the port so you have to hold the cord or turn it just right to get a sound out, and the lovely screeching static when first turning it on is always fun. Thankfully my hubby played around with the port so now it works a lot better instead of turning off while I’m playing, but I guess I should have done some research on at least different brands of amplifiers. I figured you plug into it and turn it on. Done.
