This seemed like an appropriate thread for a necro-update. Nektar NX-P expression pedals. They were among a pile of switching & pedal action units that I bought, with the sole intent of hacking them up for custom projects. $20 USD, everywhere I’ve seen them.
It took a few tries at the H90 Calibration to get a consistently smooth travel. Always with the side trim knob fully towards Toe. At one point, NX-P SW1 position maxed at a 0-94 range, with SW2 0-100. Yet SW2 position had about 50% of the parameter range confined to 1/4 to 1/3 of the treadle travel (+/-; parameter dependent average). I settled back on ‘polarity’ switch position 1 in the NX-Ps. Now it’s full range 0-100 (go figure).
Tighten the axis locking nut a bit for the loose travel. I wouldn’t rely on this pedal to hold a fixed wah-type position. Maybe a half-inch longer & narrower than an EV-5. The rubber feet can peel off fairly easily for pedalboard mounting. I like the grip feel on the treadles themselves. The shell is plastic all around, understandably feeling / looking cheaper than an EV-5 build. It’ll come apart easy enough to get at the guts, or swap the attached TRS cable.
No idea how these will hold up for longevity. For roadworthiness & general live abuse, my EV-5s & Reflex will stay put. But for home use, circuit-bending, or sheer cost considerations, NX-Ps function just fine. I have no affiliation with anyone; just a PSA on one bargain option. You can buy nearly 4 NX-Ps for the price of an EV-5, and you “need” a two pedal minimum for the H90.
