Thanks a million for listening mate!
Im fairly happy with the thing to be honest - pitch etc. can be changed so lots of listening to the dvds ahead for me
It runs on a 9v wall wart power supply so Im hoping some electronics whiz locally can build me a rechargable battery pack...
If anyone is interested the power supply outputs: 9VA 830mA.
I picked up two of these - one for my costume (whenever that will be) and one for my music studio

They were a guitarists effect line a few years ago but I think they didnt do very well. Initially the Alesis series went for $130 but towards the end they fell to $30 blowout... All the ModFx series are getting more and more difficult to source these days so much so that I had to pay just over the initial retail for both of these from different folks!
If anyone is interested, I'd suggest picking one up as soon as you can find them as I think they will become a cult thing - they are already fairly difficult to find...
Anyhoo, thanks again for listening again mate!
