The Sandstone is a silicon treble booster. Inspired by the famous Rangemaster, it draws inspiration from the latter's sounds and expands its sonic possibilities. It is also more reliable thanks to its two selected silicon transistors. The Sandstone is a reworked homage to this 60s classic, of which we wanted to preserve the sonic warmth and particular dynamics while giving you more options at the tip of the foot. Finally a treble booster that can be used in any situation!
