Dumble Heaven Mod
Hi guys I'm new here and thrilled to find your group. I have built a few Fender Tweeds and a JTM-45 combo amp. I recently graduated to AB763 circuits. I am building a Fender Twin Reverb and wanted to try Mr. Dumble's Jazz/Rock and Boost circuit for a Twin. Has anyone tried it? Does it work as posted...
