Let me tell my story, I'll make it brief. Today I received my Mission EP25k expression pedal from PGS for use with my Strymon Mobius. I bought the 25k because that's the one Mission suggests using with the digital stuff that likes to see higher-value pots. I get it unpacked, plug it in, struggle a bit to get it set to a parameter and define the range, and the weirdest thing happens: it kind of works, but instead of sweeping through the parameter evenly from heel to toe, it goes up to peak around mid-way through he treadle and then back down again as the pedal is depressed the rest of the way. So for example, if the pedal is defined to sweep from a slow BPM to a quick one from heel to toe, what it actually does is start at, say, 90 BPM, hits 500 BPM at 50%, and then slows back down to 90 BPM by the time the treadle reaches 100%. Super weird, right? I figure there must be some setting I'm missing that calibrates the sweep of the pedal, so I call Strymon and talk to a guy named Hugo. We went through all the diagnostics. He was having me check things, I had the baseplate off the expression pedal and was turning the pot by hand, the whole 9 yards. I think I stumped him, because he decided to get with his analog engineer and call me back. About an hour later, I get the call - it's Hugo. Apparently he and the engineer rigged up an expression pedal with pots ranging all the way up to 100k to try to duplicate my issue, with no luck. They couldn't recreate it. He explains that it must be some voltage issue with the pot in the pedal or something. Super apologetic that they couldn't solve the problem, he tells me to call back if I continue having problems after sorting out the expression pedal with Mission or PGS. On a wild hunch, I decide to swing by a shop (I was out when the return call came) and pick up a new 1/4" TRS cable before heading home, and guess what? It worked perfectly. Something between ring, tip, and sleeve must have shorted out on my old cable, because it turns out that was 100% the issue. Problem utterly solved, and nothing was wrong with either the expression pedal or the Mobius. I'm just a dumb ass and didn't check to see if my cable was good before calling Strymon, and they went way WAY out of their way to try to help me. It was totally not their fault that they took me at my word when I said I was using a good cable. So that's my story; the moral of which is to buy with confidence when it comes to Strymon stuff, because even when you use a bad cable it still KIND of works, and their employees will go as far as rigging up test equipment on-demand in order to provide you with support.
