Suhr - ISO Boost
If you need alternative high-gain sounds without adding another amp, the Riot is the ticket to high-gain heaven in a small package.
ISO Boost™ incorporates a clean transparent boost, as well as a transformer isolated buffered signal to drive long effects chains. 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.
The internal 9V battery is monitored at both power up and during use. The user will be alerted when the battery voltage becomes low. When the battery becomes too low to reliably operate the pedal, True Bypass is activated.
