Fifteen years ago(!) I built the Highway 86, my last tube amp project that made it all the way to finished. I put in a little time on prototyping Verberator II / Murgatroid ideas after that, and ended up bailing when the amp ideas and life both got too complicated.
The point is, the Highway 86 is good enough that a friend offered me $700 for it! I couldn’t let it go, but it sold me on simple amp designs. We’ve got plenty of great hardware & software available for reverbs & effects, but the sound & response of real tubes are what keep me playing guitars.
