I got like $550 saved up and i came upon the decision that a new amp would help out my sound alot more than a new bass would. Currently i have a crappy little behringer 120W combo amp, and i stumbled across a Ampeg B100R 100w combo amp that i really liked. so i was wondering if i should trade off the extra 20W for a much better quality and in my opinion sounding amp (at low-medium volumes at least. didnt really get a chance to crank it). Also would i, and the crowd, really even notice the difference in volume?
