If you want a JCM900 kind of sound with a lot of gain this can be an alternative to get close to that sound.
It does not do well at lower gain levels bus sounds pretty good doing the high gain sounds.
The gain knob on mine stopped to work after a week or two and the pedal is stuck on max gain, but for the moments I want a modern maxed out JCM-900 sound it does OK.
(My other Yuer pedals are working great, so this is probably just a single componant that stopped working as they sometimes do).
