Two way bypass utility module
This ‘Bypass’ module gives you the option of bypassing or swapping modules in your audio chain.
You could for instance remove an FX module, swap between different filters or compare the your clean signal with same audio being fed through a wavefolder. Each of the ‘paths’ has a return attenuator so you can match levels between different modules.
If nothing is plugged into the return jacks the send signal is normalled to it via the relevant attenuator, so you can just plug an FX unit into path A or B and bypass it when required using the switch.
The attenuators are optimised for audio (tapered) but the module can be used for control voltages. Turn the attenuators all the way up and you can even use it with gate signals.
