Just picked this up this weekend. Literally took me 3 trips to the guitar shop to compare/play back and forth vs a Marshall DSL40C. Also tried a Fender Bassbreaker 15 for a few minutes. That one didn't last long. Ultimately I chose the HT Club 40 - just sounded better to me and more versatility. The DSL 40C sounded sort of fizzy to me. Better cleans on the HT and also more range, from Metallica to Nirvana to Black Sabbath.
Just gotta get that Celestion 70-80 broken, so I can decide if it's worth upgrading or just leave as is. Other I freaking LOVE this thing. Sounds amazing with my SG Standard! Definitely an upgrade to the Fender Super Champ XD I was using. A wee bit heavier too, that's probably the only downside.
