UNIVERSAL BYPASS
Most effect pedals offer either true or buffered bypass. All Soundblox 2
pedals offer Universal Bypass, which allows you to select between the two.
We recommend that you choose between the STINGRAY’s active analog (a.k.a.
buffered bypass) and relay-based true bypass (a.k.a. true bypass) based on
what is needed in your pedalboard’s signal chain. Ideally, the first pedal in a
signal chain is a buffered input followed by true bypass in the rest of the
signal chain.
By default, the Soundblox 2 STINGRAY Multi-Filter is set to use the relay-based
true bypass. To switch the pedal to buffered bypass, press and hold the right
footswitch when powering up the pedal. Continue to hold the footswitch
until the corresponding LED blinks 3 times. The pedal is now in buffered
bypass. To switch back to true bypass, press and hold the left footswitch
while powering up the pedal.
Both bypass methods have pros and cons associated with them. Buffered
bypass provides consistent input impedance so that if the input is
susceptible to variations in input impedance (similar to a guitar pickup),
there won’t be a noticeable change in tone. True bypass has the benefit of
providing a dedicated hardwired bypass signal path; however, it can cause
clicks and pops, and typically requires a mechanically complex 3PDT (3-pole,

QUICK START
1. POWER
To power the unit, connect the included DC adapter power supply to
the 9V jack (A) on the back panel.
Note: Using a non-Source Audio supply could damage the unit.
Please be very cautious when using 3rd-party power supplies.
2. GUITAR/AUDIO CONNECTIONS
Using standard ¼" mono cables, plug your guitar, bass, or other
instrument into the GUITAR IN (B) jack and from the GUITAR OUT (C)
jack to your amp or other audio device.
