Okay, here's my post-gig report. FIrst, I should explain that I played tonight in a reggae/rocksteady band. While we have six musicians we are not really that loud. Nonetheless, I have a drummer, percussionst, another gutarist, a sax and an electric bass to contend with, so presence from my amp is important. I'm happy to report that I had more than enough volume, headroom and sense of presence from the 150 amp. Also, the four patches I settled on worked well for me during the gig (I did not use any really distorted patches. I prefer to use an overdrive pedal). I was happy with the quality of the sounds I was getting. The highest volume setting I had for the amp was around 11 o'clock -- less than half the amp's potential volume gain. Even at this setting, my guitar volume was mostly rolled back to about 40-80 percent of full. Basically, there was a lot more volume left for me to use. In fact... I'm wondering if a 75 might work for my needs. I suspect a 75 could reach appropriate volume levels, but I wonder whether it would have enough "umph", depth and full dimensional feel. I may have to go back to GC and re-listen to the 75 with these considerations in mind. It's sure hard to beat the 75's handy size and weight!
