I am in the market for a new bass head. This will be the first amp I have bought in 14 years. I am looking at the GK MB200 and the Carvin BX250 and/or others. This is the price range and wattage I want to stay at. I want a nice clean tone and I love the sound clips of both amps listed above, so at this point these are the top two amps for me. Let me know if any of you have these and your thoughts on sound and quality.
