Introducing the first fully controllable “PURE VACUUM TUBE CORE” Tube Ringmod Module.

This unique Pure Tube Core Vacuum Tube Ringmod incorporates a pair of dual diode vacuum tubes in place of the solid state diodes normally found in ringmod effect units. This gives our ringmod a tonal quality few have ever heard.

Greatly exaggerated tonal variety is made possible with complete control over:

SIGNAL input and feedback

CARRIER input and feedback

SIGNAL & CARRIER mix and WET(effect)/DRY mix.

Feedback control pots are attenuverted. Center is neutral, counter clockwise is negative, clockwise is positive.
