This is a great little amp! I purchased the Dean Markley GT1000 Micro Amp in order to be able to use it at the Maryland Renaissance Festival where my duo, Flatpickin, are street musicians. I wanted to give my instruments a boost, but needed something small enough to hide in a purse or pouch. I'm using it with the Dean Markley transducer, since I switch instruments back and forth. For this the overdrive was necessary, because it has not preamp. Sounds great! I has just enough power, so I don't have to beat my strings; yet, it sounds completely natural.
