Alexander Pedals


The Litho Boost is based on the classic Pharaoh AmplifiersClass-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 thendid absolutely nothing to it.


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.
