My main effect unit of choice is a Boss ME-6B multi-effect unit from the early 90's. I bought it because I'm a major Stuart Zender fan and he used one when he was with Jamiroquai. It has some amazing effects in it -especially the dynamic filters/synths. Even the digital fuzz sound is really unique. Here are a few examples of what it can do:

The only problems I have with it is that it's made of plastic, the compressor isn't too great, and the jacks are all just mounted directly to the circuit board. Some of the jacks have started feeling loose. If I DID replace it with stompboxes, I'd probably go...
DIY Mutron III clone >> Rocktron Deep Blue >> BBE Optostomp
I'd miss out on having the fat fuzz and synth effects from the ME-6B, but the signal path would be 100% analog and the construction would be far better. Maybe I'm just rehashing Zender's old tone too and should work on my own sound.
What do you think?
