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 MANTA’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 MANTA Bass 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 3P3T (3-pole,
3-throw) switch. Soundblox 2’s special relay-based true bypass eliminates
the need for the 3P3T switch and thus the popping/clicking problem.
