Pedal Build: Big Muff Pi – Update

It’s done! This is an EHX big muff – 73 Ram’s Head Clone. I used the pcb from GeneralGuitarGadgets.com and the parts from MammothElectronics.com

To be honest, this pedal has been done for a while. I was just waiting on the Hello Kitty stickers. I made it all pink with the stickers as a tribute to my old hello kitty guitar,  which I originally purchased 10 years ago. I thought it was hilarious to play hardcore shows with it. Here’s a few photos from the “good ol days”.

Pedal Mod: VOX V847 Wah – Update

So I found a few articles talking about stacking the capacitor value on the V847 to get different sounds. I found the right capacitor using the article HERE.

I added a SPDT on-off-on to toggle between a bass wah(47nF), stock wah, and a more throaty wah(12nF).

In between doing this mod and posting this update… I accidentally dropped my wah. The fall ended up breaking the switch, but I just ordered a new one. I should have it fixed next week. I’m also curious about investing into a Fasel Wah Inductor to replace the stock VOX one.

Pedal Mod: VOX V847 Wah

I haven’t used my wah pedal in years. I stumbled across some mod ideas from Wampler’s Book. I looked online for some tutorials and I found this dude’s video. I pretty much followed it step by step.

Here is the new true bypass switch and LED.

I also removed the old panel mounted DC jack and added a more modern version.
