I got this today!
I wanted to hear something akin to the Foxx Tone Machine, and apparently this is a bit of a clone. I paid £25 for it which I thought was alright for something to mess about with.
It's built pretty badly. haha. Controls are Level, Distortion, Octave, and EQ.
There is a bit of a level drop when you kick it in, even the level is at max. The distortion control adds a lot of thick fuzz. The Octave switch adds an octave up. This can sound utterly nasty very easily! The EQ is a bit Big Muff. It can get a bit middy and shrill though.
It's good fun. I feel like a real Foxx would be better... but thats £100 more than I paid for this! Maybe I'll have a go at tweaking it.
