I just watched this, it's worth checking out if you have any interest in guitar effects, or in fact any electronic music.

So, having read a lot about the LM386 (op-amp) and PT2399 (delay chip), I decided to get a few to mess around with. After getting them both in the post today, I got out the breadboard and started to mess around with the LM386, hoping to come up with something interesting. This might have happened, if I hadn't busted both of them by plugging in the power supply with the wrong voltage... not an expensive mistake, but I was having fun!
Anyway, with no 386, I moved on to the 2399, and built the LoFi delay, which, as it turns out, doesn't work very well with guitar (should have heeded the warning). Anyway, one more idea down the drain, on to the next! I'd seen the Noise Ensemble on DIY Stomp Boxes a while ago, so, still hungry for something that would give me some interesting noise, I gave it a go, and it sounds awesome, I've got it as 'stock' at the moment, but am going to mess around with it over the next few days, I'll put up some sound clips when I've got something I like.
