The Litho Boost is based on the classic Pharaoh Amplifiers Class-A Boost pedal. The Class-A Boost was one of the original boutique boost pedals, with hundreds of dedicated users across the world. From time to time, Class-A Boost pedals have made their way back to our shop and we"ve been floored by just how great they sound! We started with the tried-and-true Class-A Boost circuit and then did absolutely nothing to it.
Controls: Volume — Controls the output volume of the boost. Crank it to overdrive your tube amp. Contour — Set low for transparent and glassy boost. Or set it higher for fat and juicy boost. Your call. Tone — Adjusts the high frequency content of the boosted signal. The "neutral" setting is around 2 o"clock.
Power Supply: The Litho Boost requires a 9V DC power supply with a 2.1mm pin, center negative. The Litho Boost is not designed to be powered on supplies higher than 9V and does not use a battery. The Litho Boost should work fine on a multi-pedal "daisy chain" connector, but if you encounter excessive noise or hum try a separate power supply. The Litho Boost requires approx. 12mA.
