I have recently moved into playing the bass, and I must say, I love it. I'm an old guitar player, but my last few guitars were acoustic. I picked up an Ibanez SR300 and a Fender Rumble (15W) amp to use for practice. Yesterday I was in a local music store and grabbed one of their Ibbys off the rack and went to the amp room. I plugged it in to a couple of amps with 15" speakers, and I thought I was playing a different instrument. Although the Rumble works fine for practice, it occurred to me that I will never know what my bass can really sound like until I upgrade the amp. The two amps I tried out were both in the $250 -$300 range. As I scan the web, I see that that kind of price range can get me many models, both new and used. I finally decided that I really need to take MY bass with me to try out any potential new amp I might buy. Using the above price range, are there some suggestions that anyone would give me on what I should be looking at?
