• TUBEVERB is a unique vacuum-tube spring reverb based on Metasonix R-56.
• TUBEVERB is sold individually and as part of Tube Bundle.

The Input Drive level allows adjustment to suit any signal level, from -10dBu to the hottest module audio output. By overdriving the input, tube distortion is added, then solid-state distortion effects, from subtle to extreme. The two Output Level controls allow adjustment of the output mix, between totally "dry" (no reverb effect) to totally "wet" (reverb effect signal only). An added "Wet Only" output jack carries only the Wet signal for experimentation. A feedback loop allows for direct feedback around the spring. This effect is independent of the input signal and affects any input signal. It can produce feedback oscillations whose frequency is dependent on the spring delay time and the driving signal. An Invert switch allows inversion of the drive signal to the spring input, which can produce drastically different sounds, especially on bass-heavy transients such as bass drums. The miniature reverb spring "tank" is mounted directly on the front panel, therefore there's a Blue large button that when pressed will "touch" the spring providing its sound. Many different tweaks for the spring. Three CV inputs are available. One for controlling input preamp gain, from complete cutoff to maximum drive to the spring. The other controls the feedback loop around the spring, for a wide range of chaotic distortion effects. The last one will trigger the spring.
