The Plush Tube FX Loop is the most affordable and flexible all-tube external effects loop on the market! Unlike other "tube pedals," the Tube FX Loop™ features a power supply with a unique regulated switching technology that takes the incoming 9 volts and converts it up to the optimal 300-Volt high voltage a tube really needs to operate best. In addition, a precision 6-volt DC regulator provides consistent DC power for the tube filament assuring lowest noise and consistent performance despite any changes to incoming line voltage.
It can also be used as a tube buffer to convert an incoming high impedance signal to a low impedance for long cable runs or driving a pedal board. The recovery (gain) stage can be used to boost the level of a guitar or pedal board with a true tube audio stage. It provides a warm sweet utility gain stage with a multitude of uses. The Tube FX Pedal features a unity gain cathode follower to work with any amp that has passive preamp output - power amp input patch jacks, and to add features to amps with simple series active effects loops.
