I'm ready to pull the trigger on a new bass amp. I had a thread here a couple months ago wanting opinions on the Markbass CMD 151 Jeff Berlin. While that amp is at the top of my list I am making a last effort to see what else I may consider. My question to you is how much wattage do I really need? I am a blues guitarist that's moving into the bass side of the blues (blues jams). I play only small to medium sized bars. The drummer is never miced. The guitarist seldom plays more than a 65 watt amp. Thanks.
