Sedona Custom Synth

Sent to me from Eric of Metasonix. This is a DIY synth from Dave Wright. Title link takes you to more info and pictures. Love the cats. : )

Sedona

"Dave Wright of Not Breathing took a dead Crumar Stratus and did this to
it, using various modules, mostly devised by Synth-DIY list regulars.

In fact, Dave is one of the most prolific DIYers I've ever seen. Look at
the galleries at carrionsound.com for more."
