If you can build kits, then General Guitar Gadgets has 3 marshall in a box pedals....the bluesbreaker clone, the Guv'nor, and 'Brown Sound In a Box'. The former two are fantastic as I own them and they'll stand alongside boutique pedals. The BSIAB I'll be getting and making soon.
Might be a big question to ask, but is there anything decent "Marshally" sound pedal for a $100? Maybe $150? Looking for more of a JCM800 tone.
It be nice if was true bypass too....
Alot of the Wampler stuff is awesome...I highly recommend Wampler!
