Ge0sync Synth TB-EF TB-303 Inspired Env & Filter ModuleThe TB Filter Envelope module is inspired by the filter, envelope and accent circuits of the Roland TB 303. It copies the same 3 and a bit pole low pass filter and most importantly the resonance feedback loop. Like the original it has pots to control the Cutoff Frequency, Resonance and Envelope Modulation. These are true to the original in their operation. The envelope is controlled by a CV gate input that triggers the envelope and the filter

Does Not Fit Polaris Ranger
Not compatible for Polaris Ranger as it was advertised. Not the correct thread so it will strip. Do not buy if you need it for a Polaris UTV.
