I’m kind of at a loss for words with this one, so I’ll toss out ‘Wow’. Built straight up following the build document. Initially planned to audition an OPA2134, a JRC4559, a TL072, and an NE5532, but only got as far as the OPA2134. I’ve run through all my electrics including a trash picked First Act and my Magnatone lap steel – the T-Drive plays well with everything!
Here’s the face:

The box is a textured white 125B from Stomp Box Parts, knobs are from Loves My Switches.
Here’s the guts:

Thanks for looking,
Chuck
