(bought at car boot sale for 99p hehe)

holy shit - since removing the offending resistor in the plastic tube (thanks circuitbenders!) the whole things opened up - added a volt crash, vol control, output, feedback loop and pitch control. seems a lot of the interesting sounds are made by crashing the unit out of pitch range (whilst bringing the voltage down) the thing is a screaming monster now
havent even finished investigating hehe!

I got one of these for £2 and thought I'd fried until I realised about the fuse. So I bought another form ebay for £1 in the meantime and now I have 2.

It's a very versatile with  loads of sounds and possibilities, I've opened it up and had a quick look, but haven't soldered anything on because I've been busy with my casio ep-10 (nearly finished).

I found a bend that just makes it crash and cycle through all the sounds it has at random at a very low pitch, very weird I'll take another look tonight and maybe start work on it. Any chance you could tell me where the feedback loop can be found? I was thinking of putting a push-to-break switch on the output so that I can mute it while it plays the tune when you move the slider, would make it easier while playing live I think.

 I'll post anything interesting I find and hopefully we'll both have some interesting machines. I've already started learning to play it too, but it might take a while to master.

gonna take some pictures when i get a second... soz for the delay been kinda busy at work

Hey did you ever take any pictures of your bends, i'd love to see them as well.

Removing that resister has really done the trick but I cant seem to find the feedback loop.

apologies for low quality - had to just grab this real quick - read note for information on how to get the thing working nicely...
