I'm primarily a guitarist, and quite familiar with all things guitar. That said, I feel like I can kind of find my way around bass gear with a little help. Being new to bass, I thought I'd plug into a forum and learn a thing or two. I'll probably try and lurk and learn, but I had a few questions about amps: I've always wanted to own a bass to casually learn and have around for recording or filling in with some friends and recently came across a used SX (LGT description) that I really liked. I played it in a little Orange bass amp and it just sounded really great, so I've been tempted to go for it. That puts me in the market for a bass amp. I'm not opposed to buying used, but there are a few questions I had: 1) I noticed that 10 inch speakers are really common on bass amps. In the guitar world 10 and 12 inch speakers are the norm, but 12s tend to be the preference. In the bass world is 10 inch the preference? 2) I assume since I'm buying entry level stuff that whatever I get amp-wise will not be a high end something-or-another, but a modest solid state amp. I'd still like to have enough to compete in a band-practice setting (against a guitarist and drummer). How many watts will cut it. Would something like a 1x10 or 1x12 suffice? 3) I'd say $100-150 price range for an amp. Any recommendations? My favorite bassists are Tim Commerford (Rage Against the Machine, Audioslave), Chris Wolstenholme (Muse), and John Paul Jones (Led Zeppelin). I'd love something loud enough to compete with a band, but also can still do some bedroom levels. Thanks for your help.
