Hello. I have a Boss GT-1000 and have used many similar Boss pedals before. I've been using an EV-5 I bought new years ago and although it was never as good as the onboard, it does what it supposed to. Works perfectly on the GT-1000 now that I've repositioned the pedal to the pot. However, I have a second one I bought used and It simply will not travel the range properly. I'm not a wiz at electronics. I've built some small things and wired guitars and appliances etc, but I need some help figuring this out. This thing is simple as heck but it does not work. I took it apart and checked the components of both pedals. Tested values. I just don't understand how this thing works. There is a 50k and a 10K involved. I've reversed them and I get the same result. I took the 10k out and soldered a 350k (dont ask me where I got such a thing IDK) in its place and that did NOTHING except confuse the hell outta me.
If I remove the pots from the pedal and rotate the 10k with my fingers 100% it actuates the GT perfectly. From 0 to 100. The problem is the physical pedal will not rotate the knob 100% so I basically get no farther than 50% travel. If you're not familiar with BOSS GT pedals you should know they do not allow calibration of exterior pedals. The original EV-5 does everything the same as this one yet it performs properly. There is a 10k on the pedal and a 50k adjuster on the side. See schematic.
I feel like 10k is not enough resistance to get to the finish line with only 39% travel but I also feel this is wrong thinking and I'm missing something.
My good pedal reaches 8.31k at the tip but the second pedal only reaches about 4.30k with the same values and construction.
What can I do to make this thing work right?
