Fifty Six Pedals is a Brazilian boutique builder specializing in 100% tube preamp pedals that replicate the preamp sections of classic high-gain guitar amplifiers. The company's flagship Tubestation series puts full-valve circuits into pedal-sized enclosures, letting players get amp-like voicings into any rig or recording chain.

The Tubestation line includes several models voiced after iconic amps: the Tubestation 2plus is based on the Mesa Boogie Mark IIC+ preamp, the Tubestation Rectifier mirrors the Mesa Dual Rectifier, the Tubestation XTC draws from the Bogner Ecstasy's blue, red and plexi channels, and the FS Tubestation 5150 is built around the Peavey 5150 preamp circuit.

The pedals are hand-built in Brazil in limited quantities and sold primarily through Reverb and direct channels, giving them a small, word-of-mouth reputation within the high-gain and metal pedalboard community.

Fifty Six Pedals has 1 product cataloged on Equipboard, including Guitar Preamp Pedals.
