Monolith Grey Owl Modified Silicon Sustain Pedal
The Monolith Grey Owl takes the Muff blueprint and pushes it into darker, smokier territory, with a growl that’s as complimentary with bass as it is guitar. Using a rare mix of NOS Motorola BC239C alongside BC108 and BC107 metal-can transistors, it balances warmth with bite, while the blend of silicon and germanium clipping diodes adds a unique throaty snarl. The tone circuit is voiced to shine further up the dial, making it fat, clear and surprisingly versatile.
