0HP Modules are passive circuits you can use to add utility without adding another module!

0HP Vactrol based modules take advantage of an outdated part to rough the edges of your sound. What sets Vactrol-based circuits apart is that they will slow down any incoming control voltages, allowing them to convert a gate or trigger CV input into very musical envelopes. Both the Vactrol Low Pass Gate and the Vactrol Voltage Controlled Amplifier modulate the amplitude of a signal under voltage control, but the VCA does so with minimal alteration to the sound whereas the LPG filters the sound to give it some extra weight. Both modules feature a 'mix input' allowing for passive mixing with other sound sources or daisy chaining of multiple Vactrol modules. Please note that all Vactrols are unique snowflakes and as such each module will have a different response curve.



Whether you need some extra utilities for your studio behemoth or you need to save space on the road, 0HP gives you options. These modules come as a small circuit board mounted to a colorful piece of laser cut plexiglass, with a small chance to get one of our fabulous rare colors.

‍DISCLAIMERS:

Since the modules are passive, some signal loss and distortion should be expected. The user is expected to keep cables away from the top of the circuit board. While in 99.9% of cases an accidental short circuit is not an issue, Mystic Circuits, Eli Pechman or any of our retailers assume NO RESPONSIBILITY for modules that are accidentally damaged by doing so. This expectation follows same logic as not plugging an output into another output or touching your cables to the panels, which are common safety practices expected to be followed by the end user.
