• TUBESUPER is a vacuum-tube voltage-controlled oscillator (VCO) and voltage-controlled filter (VCF) based on Metasonix R-54.
• TUBESUPER is sold individually and as part of Tube Bundle.

It uses a triode-pentode in a unique Wien-bridge circuit, to provide clean sine-wave oscillation. Using a Vactrol, the pitch of the TUBESUPER is sweepable from less than 20 Hz to more than 5 kHz, continuously, via front-panel control or a CV input.

Turn up the overdrive control, and the oscillator output clips the output amplifier pentode tube, for a unique soft-clipped square-wave sound.

A VCA CV input allows you to control the output level of the TUBESUPER as well as the amount of clipping in the output tube. Plus, a feedback adjustment more useful when in VCF mode.
