In addition to buying an oddly shaped purple guitar. I've also had a minor Boss pedal buying spree.
A (used) Boss GP-10 for my 'guitar synth device' collection. Takes a 13pin midi guitar signal and triggers guitar and amp and fx models (its a decent multiFX for regular guitars), synth tones, alternate tunings, acts as an audio interface and midi note (over USB). And it runs on the same power as a drive pedal. Doesn't have a regular midi in or out socket which is a weird oversight considering all of the stuff it can do.
A (used) Boss RV-500. I'd like to try a DD-500 (to get some dual SDE mojo going on) and RV-500 combo. This is the start of that plan. Till then, it'll live in my rack's 'Time' drawer with the other Boss goodies. So far (after one evening with it. Its got some great reverb sounds. I do like a good Hall or Plate reverb, and this has very good ones. Can it do a 'Big Sky / Cloud' sound. Very nearly. Its odd that Boss don't make an RV-200 to fit in with the other XX-200 range. But the XX-500's have regular midi sockets, which is a winner for me.
