Maxon Dual Booster PRICE: $125

2 completely independent boost circuits in a single compact housing. The Clean (Left) channel offers up to +20 dB of clean boost with a completely flat frequency response. The Vintage (Right) channel is Maxon' take on the classic Treble Booster circuit. It offers up to +20 dB of boost, but with a subtle high-frequency roll-off that increases as the Level is turned towards maximum.
