Digitech RP55 with Wah pedal
I bought a cheap multi-effects pedal but very versatile and tons of good tones on presets available for use. However, there's no expression pedal for WahWah and the auto wah option that came with the preset is good but not satisfying. So I did a bit of hack on my Digitech RP55. And with that I converted it to a Whammy pedal and Wah pedal. All I did was bought from eBay a generic expression pedal. It was an M-Audio keyboard universal expression pedal. It's also cheap so I thought to myself, what can go wrong. I can always open it up and change circuitry inside. So I plug it in, then turn on the wah option and when I tried it, it was the wrong way around. I think the polarity of the keyboard expression pedal is different from a wah pedal.
Sol I tried reversing the polarity by inverting the jack’s wire. But nothing happened, it was still the same. Then, I moved to rotor inside and reversed the polarity. Although there were three wires, I was lucky and managed to reverse the polarity. My pedal now is working properly as a wah pedal. I even tried it on the whammy patch and it did work as well.
What I did next was improvising on making it a proper mini pedalboard. First I look for a flat wood or something that I can put my Digitech RP55 as well as the expression pedal next to each other. I found our old wooden square placemats. Then, tried putting the effects pedal and expression pedal together and it was perfect fit. Next, I bought some arts and crafts materials like glue and coloured foam sheets. Glued one on top and one at the bottom to prevent the wood from slipping or sliding. It served as a cushion. Then, I created a bit of designs like stars, etc. I also bought velcro so that I can remove my effects pedal if need be and stick it back to my improvised pedalboard again. So I glued one part of the velcro on the effects pedal and expression pedal, then the other part was on the pedalboard itself. Perfect fit and very handy.
