Any DIY for Way Huge Tone Leper, Boss Spectrum, or other mid boost?

[msb69]

I'm looking to build a pedal that is a mid-range booster like the Boss Spectrum, Way Huge Tone Leper, or Dunlop Q Zone.  I want to get that "fixed wah" tone ala Michael Schenker and others . . .

Thanks!

You could try the Small Bear Wild Mouse project: http://www.smallbearelec.com/Projects/WMouse/WMouse.html

i know you're probably interested in DoingItYourself but i have a true bypass version of the Boss Spectrum that Stuart Castledine (the "wah-wah" and "greenfuz" guy) did for me in 2002.
it only needs rehousing (hammond BB box) and a power hookup, and you're ready to go.
i promised pics some days ago, and they will come soon..

if you want the "guts", PM me! i don't need it anymore.

This one works well too (courtesy of Jack Orman):

Any way to mod that for 9 volts (add biasing or something)?

Yeah, just run the connection shown as ground in the drawing to Vref and you're pretty much good to go.  The original Anderton circuit was actually intended to be run off a 9v battery.  jack has trimmed it back for fitting into an existing circuit.  The original has an initial op-amp buffer stage and also adds an output volume pot, but this little fragment can easily be inserted into other projects.  Incidentally, you can cascade a couple of them, tuned to different resonant frequencies if you want.  Just keep in mind that when the resonant boost is "on", it has a gain of x2, so if you cascade a couple of them you want to make sure the gain doesn't run away on you (2 x 2 x 2 x 2 can quickly escalate).

Colorsound inductorless wha, a very good sounding one trannie circuit.
