What kind of expression pedal works with the Analog Heat +FX?

I recently learned the hard way that there is no universal standard for expression pedals, and that things I thought would play well together actually don’t. For example, Eventide and Strymon expression inputs expect 10k and 50k resistance respectively. I bought some OBNE expression pedals which are advertised to work well with Strymon pedals but produce a logarithmic curve response in the control signal when plugged into an Eventide H9 or H90. (this is actually a pathway to some happy accidents but ultimately not what I was intending)

So what about the AH+FX? What specs in an expression pedal will lead to a steady, linear response?

TRS 10K resistance?
TRS 25K resistance?
TRS 50K resistance?
Something else?

PS I could not find this info in the manual

I’ve used 100k and 10k (linear pots) expression pedals, they both worked great, you calibrate to the pedal used, so it should be pretty flexible

That is a good sign, thanks for the response

I’ve successfully paired (well, tripletted, really) this

and this

with the AHFX

along those lines, i made my own quad expression knob pedal to work with the Analog heat and my osmose

the osmose jacks needed 100k pots and tip and ring swapped. i’m using 10k for the other 2 jacks

Nice idea and cute name on your pedal!

How did you create this pedal? It’s super dope!

I have a friend with access to a laser cutter/etcher, so I etched the graphics at his shop, the rest is pretty basic: drill some holes. Hand wired/soldered the parts, used some guitar volume knobs for the top; the numbers on the knob line up with the lines on the graphics from the bottom.

  • 10k pot (or 100k depending on the device)
  • 1k resistor, 3 wires
  • TRS jack
  • parts from nextgen guitars (diy shop)

I made 4 of them. I have one with different wiring to handle line 6 style expression inputs, 2 knobs on a single jack; and I have one with a switch instead of a knob for sustaining drones.

here’s the guts
