Amazing amps. I have the B+ Pro Stock, which I am selling (will post this weekend). the B+ drops the overall wattage a bit down to like 80watts, according to Scott. It's a Marshall Killer, and I've owned several Marshalls as well as a Bogners, Budda. I've tried other great amps like the Smallbox, BE-100, Cherry Bomb, and my Splawn did what I liked at a much lower price. Still, those other amps are amazing.
Splawns are dynamic and responsive. They can be picky with some speakers, I found. They are SUPER quiet for high gain; when I first got mine it has a bit of a hiss, but that seemed to dissolve quickly after a few days. The loop Volume allowed me to get my tone at small to big clubs. I live in a small apartment, and it was OK for apartment use, but it's not an apartment amp. But no amp over 5 watts is an apartment amp, IMO.
I was going to get another 50w Splawn, but I've decided to go the modeler route.
I called Scott a few months back and he said the QR/PS can do Nitro whereas the Nitro has a harder time doing the QR sound.
Scott can do some custom options on his amps as well. One CANNOT go wrong with a Splawn.
