Flat V is a collaboration between Josh Smith and Poly Effects.
Flat V is a gain pedal with 2 channels. Channel A is transistor based with selectable diodes. Channel B is amp style gain circuit with cascaded JFETs replacing valves. Synth style resonant filters shape the tone of channel B.
 
All presets have 2 sides that allow you to blend between 2 values of each slider. You can blend with the waveshapes, MIDI or an envelope that reacts to your playing. Blending allows very complex tremolo, envelope filter and auto wah style effects.
100% analog signal path with digital control. Flat V has full MIDI control over all sliders, switches, channel routing, blending and preset control. Requires a 150mA 9V centre negative power supply, not included.
