Well, good enough if you go for blues or 80ies/90ies classic / progressive rock. Great boost channel. Reverb is ok, but not really impressive. Nice, but no all time favorite.
I replaced the tube with a Tung-Sol, had to clean up the pots, and it had the annoying dropping out of volume thing due to the effects loop (solved by putting a cable through) would love to replace the pots and jacks ....one day! sound wise I love it, and because its a solid state power amp, you can remove the speaker cable to record!
