[sdiy] Whammy Pedal Mods?

[Sean Costello]

Line 6 is apparently contemplating the idea of allowing 3rd parties to develop and sell (license?) algorithms for their Tone Core pedals. The knob interface and ROM of the Tone Core pedals is a unit that can be removed from the basic Tone Core chassis. The DSP is a Motorola 56364.

Not really DIY, unless you run a company that produces commercial effects. Also, not sure what the manufacturing/profit model is.

As far as DSPs that can overcome the A/D and D/A problems, take a look at the upcoming ADAU1701 DSP from Analog Devices:

I haven't used this DSP, but I have seen it demoed at AES, and it seems like it might be useful for simpler digital audio applications. It has 2 ADC and 4 DAC on chip, so all you need is EEPROM and a crystal and you are up and running. Not sure if it will have an external SRAM interface or not - you would need it for any delay applications beyond chorus/flanger territory. The development tool, SigmaStudio, is like Max/MSP, if Max/MSP wasn't ugly as sin.

  This opens another question though... are there any bits 
  of gear that people have re-written operating systems for?
  Some people (NOT me!) are hot on programming, but stopped
  by the not inconsiderable a/d d/a interface hurdle.. maybe there are some
  cheap audio fx units that are useful as a DIY DSP platform?

    I just bought the newest version whammy pedal the other day and it seems to have a design "feature" (flaw) that I didn't expect.  In the harmony modes there is no way to get a 100% wet signal.  Does anyone know of any mods for the whammy pedal to provide the 100% wet signal?  Is it hopelessly SMD and complicated in there?  I am hoping to hear from someone who has poked around inside a whammy pedal before I decide to void my warranty.  I bought it new and I can still return it.
