The Iso Boost is the ultimate boost pedal and line driver that expands the range of your tube amplifier. Iso Boost features an easy to tweak layout which include a Boost control and a two position Iso (Isolation) switch. 


Boost: Adjusts the amount of boost from the circuit, from Unity (0dB) to +20dB of gain. 

ISO (Isolation) Switch (two position): Activates a transformer to isolate the output and eliminate ground loops between amplifiers and effects.


Left: Isolated transformer, buffered output


Right: Non-isolated, buffered output 

Note: Iso Boost is always buffered.
