The Sinkhole is perhaps our most ethereal reverb unit to date. We’ve combined a harmonically-rich “hole” reverb with an impossibly deep four-voice chorus that’s been outfitted with a feedback control and a gentle high-cut filter. Within this arrangement, the feedback control allows the Sinkhole to reach deep within the reverb to extract some truly otherworldly tunable modulation, featuring everything from comb filtering to pseudo-phaser to haunting auto-filtering. That aspect never gets out of control; it’s all wrapped up within the confines of the reverb. We’ve stretched the reverb trails out to their absolute limit, with the maximum decay time almost freezing your signal in space. Extreme settings evoke warm synthesizer pads, reminiscent of vintage analog-digital hybrids, holding your modulated note indefinitely. Combine all that with a full wet-dry blend and a warm preamp circuit, and you’re beginning to feel the gravity of the Sinkhole. Let’s get pulled in, shall we?
Fact: You will enjoy the Sinkhole.
Fact: This pedal accepts a center-negative (the standard) power supply, between 9 and 18 volts DC, and with at least 100mA of current. You can exceed 100mA and it will be fine. Do not give the Sinkhole reverse-polarity (center positive) or AC supplies.
Bonus fact: if you give the Sinkhole AC or a center-positive supply, you will void the warranty. Bad move.
Figure: The input impedance of the Sinkhole is 160K ohms.
Figure: The output impedance of the Sinkhole is 18.4K ohms.
( On NEW gear we have to charge a 15% restocking fee due to people wanting to “try out and/or pilfer parts”. If NEW items arrive damaged, we can process a return. Call our shop or write in if you have any questions, we are here to help you find the gear of your dreams… )
