Custom Built Plexi with Tweaks

This is my custom self-built 4-hole amp, built to bridge classic vintage tones and modern hot-rodded gain. My Interpretation of a perfect marshall amp. Inputs 1 (High/Low) stay pretty close to a classic Plexi circuit. Inputs 2 (High/Low) switch things up with a hot-rodded JCM 800 topology, tweaked with a few ideas inspired by the Friedman BE-100. I’ve added quite a few of my own tweaks throughout the circuit to smooth out any harsh top-end and keep the highs pleasant, while dialing in a warm, full bottom end and a balanced overall sound. Even with those adjustments, it still keeps all of that classic Marshall bite, grit, and crunch you’d expect. It’s super forgiving to play and works surprisingly well at lower volumes too. The captures were taken right in the sweet spot with the Master Volume sitting around 11 to 12 o'clock. Just the head is captured using a DI out from the Ox Box. Use your own IRs
