Hey guys. I currently have a Ampeg BA-112 50 watt practice amp that I play with at home. I use a Lakland 44-02 and a Single coil P Bass that I built. I've been taking lessons for 8 months now and feel ready to start getting out there and playing with other people. But I think I'm going to need to upgrade my amp before I start playing with live drums and other louder instruments if I want to be heard. I think one of these combo amps with removable heads may be the right thing for me, like the Mesa Walkabout Scout, or the Genz Benz Shuttle 6.2-12T 600W 1x12 Bass Combo. I like that it comes ready to play, so I can get right to playing with other people, and even small gigs, and later on I can just buy a bigger cabinet and continue using the head with that for larger gigs. My questions are, what other options are out there that have this removable head style and what are your opinions/experiences with these combos? As far as what sound I like, I would like something that can give me a nice fat reggae sound, but also can cut through well for rock/punk. I guess the easiest way to explain it, is that I would like a Sting from his Police days kind of sound. Thanks.
