Muir Silicon Steel Boost

The Muir Silicon Steel Boost brings a fresh take on the boost stompbox format with a transformer-based gain stage, giving it a unique warmth.

While based in part on the company’s Silicon Steel Overdrive, this is a brand-new circuit optimized to work as a boost, although it does offer some amount of dirt: the ‘Heat’ knob lets you dial in just the right amount of saturation for a clean yet rich boost with a touch of transformer character.

With over +21dB of gain and a 2-band EQ tuned specifically for this pedal, you can shape your sound however you like—whether it’s a treble boost, bass lift, mid-focus, or a scooped EQ. Plus, it runs quietly on a 9v-18V power supply for added flexibility.
