Modifying a Cry baby Wah Pedal into a Wah/Volume/Expression

Well I got a Alter ego x4 and found I can use an expression pedal but only 25k Ohm ones
Which got thinking that I could infact use the old cry baby which I have been meaning to fix for a while as an expression pedal which seemed like a common mod.
But I can also mod it so that it can act as a wah but will have to use different schematic than the original like the Maestro Boomerang which does use a 25k Pot

Also I can put a schematic for simple volume pedal. Now with a 3 way switch I should be able to switch between the three modes.
Will need to drill holes to have 3 outs. In and Out for volume and wah. And one out for expression.


Will make it true bypass, might need to add a buffer for wah, Led mod which glows on the inside with different colors depending on the mode.

Any thoughts on this..

So in total all mods will be

  • Maestro Boomerang with buffer
    Expression
    Volume
    3 way toggle
    True Bypass
    LED different Colors for 3 modes
