MORLEY- Steve Vai Bad Horsie 2 The VAI-2 is a Bad Horsie Wah with the additional choice of CONTOUR mode. Click the footswitch to the left of the foot pedal to engage CONTOUR mode (the left side LED turns ON). The contour mode allows you to alter the Wah tone and level. CONTOUR control: Adjusts the tone (shelving) of the Wah when in CONTOUR mode. LEVEL control: Adjusts the Wah output level in CONTOUR mode. Electro-Optical Switching: Your pedal features Electro-Optical switching circuitry that allows the Bad Horsie 2 pedal to go into Wah mode without actuating a switch. Silent Switching: To further enhance the noiseless operation of our Electro-Optical design, we've added FET silent switching. Standard foot switches will pop and click when switching from Wah to Bypass. Buffer Circuit: Morley's "Clear Tone" buffer circuit prevents "loading" of the guitar signal. Ensures a strong, clean & consistent output level in Wah or bypass mode. ADJUSTABLE OFF DELAY: Refer to instructions for adjusting VAI-1 Off Delay time above. ($209.00 List)
