Title: Stand alone vibrato
Post by: bbirling on June 02, 2010, 11:54:13 am

I have a lot of extra small trannies laying around, and am interested in building a tube vibrato. A stand alone unit would be nice.
I don't need the reverb. Has anyone built something like this ?

I also found this one that is a bit more legible.
