Re: Hey Joelap!!!
I'm working on a DS-1 for ElUnoEstuto also right now, hopefully I can get started on it soon.
Basically, I up the gain, add some bass, remove the fizzy-ness of the distortion, alter it to add in more lower mids, make the tone control more usable. I try and voice it more like a tube amp, if I had to say what amp it sounds most like, I'd say a mesa mark series voicing. Good amounts of gain, less buzzy, more natural sounding. Pretty cool in the end I think.
Wahs are cool. For an extended sweep range, I can give you a couple suggestions you might be able to do yourself. First, I'm not sure if crybabies have them, but my vox 847 had a rubber stopper on the front and back of the pedal to pad the pedal against the chassis at the most extreme settings. I put off removing mine, but I did a couple weeks ago and now theres a great amount of extra sweep on my pedal. Also, open up the back and adjust the position of the pot and try it out. That might do the trick for you.
Generally, the mods I'd do to a wah pedal would depend upon what you were looking for. My "fully loaded" mod for wahs consists of replacing the pot with a Fulltone pot with ICAR taper, adding my "vintage/modern" switching options, which switch between vintage voicing and modern voicings as well as a clean sweep on the modern mode and a more saturated sweep on the vintage mode. Think cream's "white room" tone with the vintage, and a slash/STP style wah on the modern. This is acheived through two means, but the primary factor is using two inductors. I can also get the same transistors as used in the original wah pedals. There's a lot I can do to wah pedals, but unfortunately wah pedal parts are expensive so the mods can be expensive. But with wah pedals, you can choose what you want and what you dont.
