I played a Rectoverb 25 combo yesterday. I expected to hate it. I figured it'd have boxy mids and a farty bottom end due to the small open back cab. I didn't hate it. The mids were forward, but not overly boxy... and while the bottom end wasn't solid, it wasn't really all that mushy either. I wound up having a pretty favourable impression and liked the uniqueness of the sound. What I'm worried about is how it will sound at a proper volume. I demoed the amp at what I'll call "guitar store loud" while locked in an acoustically dry broom closet of a demo room and sitting on a stool that's about 16 inches in front of a 1x12 that's sitting on the ground. Not exactly realistic conditions. I'm worried that as the volume goes up the amp will become more boxy and the low end will become less defined. Anyway... any thoughts on the combo version specifically? How'd it work/not work for you?
