Okay, I've researched and asked questions about these two babies, and now I want your opinion. I'm in the market for a new combo to keep me occupied (and to better equip me than my Crate BX-15) until I get enough money to buy the GK stack I want. I'm looking at either a Gallien-Krueger 400RB/210 Combo (240W) or a Fender Bassman 200 (200W). I've heard good things about both. I am a little confused about the GK, though. It says 240W at 4ohms and 150 at 8. How do I switch from 4ohms to 8ohms? Is there a switch or something? As always, all comments are appreciated, negative and positive. EDIT: Also, the GK is priced at $749.99, the Bassman at $629.99. Would it be wise to spend $120 more on the GK?
