MicTester Hot Silicon TonebenderVerified
Based on the MicTester Hot Silicon Tonebender
From the post
Here's another one of MicTester's creation/adaptions. The Hot Silicon Tonebender is based on the classic SolaSound Tonebender Professional Mk II, but with silicon transistors and an added tone stack. Pretty much any medium to high gain transistors will work, so socket and try a few different ones out (BC109, 2N5088, MPSA18, etc).
