This is great and easy to make tremelo pedal, redesigned by Bajaman on the basis of the Demeter Tremulator. If you want to make this pedal, you'll find all you need to build this one right here.



It uses a vactrol device you can easily replace by whacking together an LDR and a LED.
Yes I am out of jack and only had this 24k golden jack left. Envisioned a slow/fast switch but there simply wasn't enough space in this box.

thanks Baja, you're great
