Reviews can be found sufficient for the BadMonkey in other forums. A stomp of reliably making its service. The Fender Stratocaster in every setting with a superb and powerful sound. Thought I have to get the BadMonkey for my Ovation some pieces a little more pressure. Very decent machine with good workmanship, robust reliable, hardly noise as disturbing hum etc. would be helpful an indication of the polarity at the power connector. The can also be found in the manual in vain. A 9V battery is been present at the delivery (at least for me). I could rock out immediately.
