Awesome little dirty sounding synth, I personally only ever used it with a driven guitar amp and with tons of the really awesome trashy bucket brigade delay for cool pad chords for a lo-fi ambient post-hardcore thing with my wife. We've got 2 small ones that don't give us much time for that sort of thing ATM so this is lying around sadly unused (and we're a bit skint) - will absolutely getting another when we're back at it.

Some cool options allowing you to have a quite a few different tones, and if you're not using the step sequencer there's a cool hack for saving settings on the steps for different presets if you're using an external midi controller/input. I generally used the poly mode which has 3 note polyphony for chords which sounded ace with a bit of detuning and aforementioned delay colouring.

Speaker works fine not that many will be bothered. I do have a 9v centre positive adaptor for using with a standard guitar pedal power brick sort of thing somewhere, however I've not seen it since moving so can't guarantee it. I do also have a couple of typical centre negative guitar pedal extensions that I was using before the adaptor, which whoever buys it is welcome to. Happy to make some sounds with it if it turns up for anyone that wants to hear it!
