Ran across the Tapestry Audio Bloomery pedal today. It's available in a passive format that'll apparently convert from volume to expression mode. Not sure if that'll full-on switch it to linear taper or if it'll just make the taper less logarithmic. But the size is super intriguing. It's narrower and not as deep as most expression pedals but still has a long throw. Any how. Thought it was neat. Passing along the info. If you've tried one, chime in. Good to have options!
