Plumes is a unique, all-analog approach to a classic tube-like overdrive circuit offering 3 different clipping voices, loads of headroom, and almost three-dimensional clarity that will push your amp over the edge. The reimagined tone control is finely tuned to sculpt low end, clear top end, and focus midrange with blooming sustain. Flexi-Switch Technology This device features Flexi-Switch Technology. This relay-based, true bypass switching style allows you to simultaneously use momentary and latching style switching. For standard latching operation, tap the footswitch once to activate the effect and then tap again to bypass. For momentary operation, hold the footswitch down for as long as you'd like to use the effect. Once you release the switch the effect will be bypassed. Since the switching is relay-based, it requires power to pass the signal.
