Hibernaculum

Hibernaculum is Belton-based reverberation with three reverb modules arranged in series or parallel modes, with built-it JFET overdrive, master true bypass footswitch plus wet-channel disengage footswitch allowing for echo tails and overdrive always-on use.

Each reverb module has own volume (chamber) and decay length controls. 1st chamber is purest. 2nd has low-end attenuated a tiny little bit. 3rd has low-end attenuated a tiny little bit more plus provides longer decay.

overlay mode arranges reverb modules in parallel. cascade mode arranges them in series (clean signal goes into 1st reverb module, then wet signal is processed again in 2nd, then result is processed again in 3rd). Center position arranges 1 & 2 modules in parallel and 3rd in series. In cascade (or center) mode 3rd chamber also receives additional saturation.

reuse - feedback control with high-passed signal taken from 3rd reverb module output; in cascade mode each decay setting has impact on overall feedback behavior, chamber volume controls do not.

amplitude - master volume
clean tone removal - post reverb JFET overdrive master gain
presence - post reverb master treble-cut (neutral setting is maxed)

bypass footswitch - master true bypass
reverberation footswitch - reverb effect on/off
infinity momentary footswitch - increases feedback for self-oscillation

Internal controls:
gain trimmer - allows to increase JFET gain a bit
bias trimmer - reasonable to keep it intact at factory setting

Power consumption is up to 260mA. Use center-negative regulated DC power supply only (standard 2.1x5.5mm barrel). Quality isolated 9V power supply rated for at least 300mA is recommended.

It's rather a large pedal, housed in Hammond 1590D enclosure (188x120x56mm without hardware).
