The Remix units have hit the discount stores (and ebay.) This one cost only $5 USD! With a 3V power supply, they are easily converted to AA batteries (or keep the AAA supply.)
Unlike many guitar projects, this one requires only minimal soldering and only a few extra parts. And no fabricating circuit boards, etc.
Build one like this for on-guitar use, or encase the guts in a stomp box! (use a volume petal to control the effect...)
And OK--I did have all the adapters and cables (and the textured paint) so the total cost will vary....
Keeping with the 'Ghetto' theme, I've installed one on a cheapo 70's guitar (my Les Paul looks on jealously in the video.) (Oh, and be nice about the playing--this was the first and only 'take'...)
Step 1: Parts and Supplies
Soldering iron and Solder
Small screwdrivers (for electonics or jewelers)
Textured paint (optional)
Cords and adapters (I had these on hand)
With a host of adapters, custom cables don't need to be made (and the remix unit doesn't need any retrofitted jacks, etc.) Ultimately, it DOES make sense to add new jacks, etc. and NOT to depend on adapters.
But this is a quick-n-dirty hack, after all....;-)
