Inspired by Father Moo and designed by Tenderfoot Electronics,
pinhl is a vactrol-based 3 channel passive low-pass gate.
Each channel of pinhl features 2 modes - selectable by the switch on the front panel.
With the switch in the upward position, the channel is in low pass mode.
When the switch is in the down position, low-pass mode is deactivated, and all frequencies are passed through.
