Hey I have a question to y'all pros out there. I've been playing bass for only a year so I dont know much about rigs. As of know I have an Ampeg vr micro head and the 200wcabinet that goes along with it, the amp sounds so shabby and not tight. But I found this used 1990 svt pro 3 in my local store together with an ampeg 400w 15' cab. I wonder if I should go for it and is it a good upgrade from my current amp? Just so you know I dont know much with amps, Thoughts?
