Now that's done ....
This was originally marketed as a proprietary circuit (erm .... Tonebender) which allegedly used a custom designed "Fuzz IC" which presumably therefore no one else would have access to (erm ... CA3046). Now it is apparently a modern take on the MkII, I'm not going to quote the sales spiel directly but you can read all about it here.
As usual I am often keen to emphasise that when a nice sounding effect is released by a good builder you should endeavour to support him and buy his products so he can continue creating pedals. As such I'll be making this one myself.
My interpretation of the circuit and again, company and product name used for identification purposes only. I would also point out that building this will not give you an original Retro Channel - The Fuzz, to obtain one of those you will need to buy one from the manufacturer or one of his appointed resellers. This will only allow you to build a pedal with the same circuit in a smaller box for less money. Enjoy!
