i have a vintage ross distortion and i can say that my experiences are all good. its quite a unique sound, quite tube screamer like but crunchier, almost fuzz like, but not really a fuzz. it also does the light drive sound quire well, but i feel it sounds better with humbuckers than single coils, it can be a bit trebly and harsh with singles. hope this was useful...
hehe...you should have seen the ross purple phaser/dist unit. that's their most famous one and it rocks! damn i cant rem who bought it... some one is holding on it hehehehe...
