The Electro-Harmonix Ravish Sitar pedal uses guitar signal to produce a polyphonic lead voice and tunable sympathetic string drones that react to a player’s dynamic touch. It allows the player to create custom scales for the sympathetic strings while setting the decay time for the lead voice. Used with two expression pedals (it has inputs for each), it can bend the pitch of the lead voice and control the volume of the sympathetic strings simultaneously. Learn more at ehx.com.
