Holy Island Audio Cannibal Pride Drone Synth

 Chris have done it again...

"Gwion of Holy Island Audio builds awesome stuff and, included in the package if you purchased the debut release from Gwion's band, Smothering, is a DIY PCB for a three oscillator drone synth called the Cannibal Pride. This is that synth, and it sounds KILLER - keep in mind that, as this is a sound source and not an effect, there is of course, no input."

BJFe Universal Reverb V2 / Capitalist Death Cult Actual G*ddamned Springs

 Heavily modified revebr unit by BJFe, treated by Chris Stelloh.

 

A couple of the tweaks are from Björn - in particular, the 2k2 resistor from the source of Q1 to ground. Lowering that value fixes a volume drop that can happen when the 50k dwell pot is maxed. I replaced the second dwell pot with a 10 ohm fixed resistor, so that it is almost at maximum. I also added a flat-mids BMP tone control and BC337 recovery stage that sounds really great paired with this circuit. Using a PN3269a in Q2 can squeal with feedback (a GOOD thing in my world) so dialing in the 10k output trimpot is a necessary step. It is possible to set it so that it only howls when the dwell+mix are turned to maximum. The charge pump is something I redrew from an old tagboard layout. The 555 doubler puts out 30mA of current which this verb circuit needs most of (the schematic says it draws around 20mA, and that was before I added the extra transistor) no matter what voltage you are running it at.
