Yes sir. (Possibly the little RM 300, but far less likely as it's light an easy backup, and I use it at home to not fire up the tubes.) To get the tube and drive sound I like I'm basically adjusting the vol with the output. With the input mostly maxed the output is barely on and the slightest movement can be way too much or little. Just hard to adjust in or even in between songs at times. Especially as I'm stepping around the cajon while the drummer is out. Most basses are maxed as well--other than the G&Ls. Definitely first world problems.
Would have preferred the 300 but never ran across a used one when looking. The 500 came up and I went that direction. Were I playing louder in rock gig setting it would work fine, but still more than I need. I've never "needed" more than 300w, inside outside PA or no PA.
