The fact that I own a C++ makes this amp all that more drool worthy.
This is the amp for modern metal but it will do Dumble if you prefer, I posted a video comparing my C++ to Steve Jones' Dumble on TGP and no one has flamed me because it sounds like the SJ Dumble! If you want an amp that doesn't run out of gas, this is it. Gobs of gain & zero hiss, plus you can run the bass higher without any flub. A C++ sounds very good at low volume with the presence at 10. Over the years, other amps have been compared to a C++ only to lose flavor when another challenger comes along. The C++ will always be the King of high gain, the "bar" at which all comers will try to attain and as always, fall flat in the end. Does it all except chrystal clean.
IMO, amps, guitars, & speakers get better with age and usage.
