The BYOC MOSFET Boost kit is based on the same circuit that the Zvex SHO is based on, but this one allows you to control both the gain and the volume. A MOSFET boost, has nice tight low end and adds some sparkle to your tone, but it isn’t as inherently clean as most people assume. The volume control on most MOSFET-based boosts is actually the gain control. The BYOC MOSFET Boost lets you dial in how dirty you want it and control the actual amount of boost as well. Approximately 25dB of boost at max gain setting (about 15dB when set clean).
