Option Knob’s VKnob offers improved control for electric-guitar players. An alternative to the traditional Volume knob, it enables a player to execute fine-tuned volume control and lightning-fast volume swells. Its “arm” design extends the guitar’s Volume control closer to the strumming area, making it quicker and easier to adjust on the fly, rapidly move the arm up and down to create tremolo effects at any tempo, or couple your pinky finger with the notch on the tip of the arm to fine-tune the volume level on every individual note you pick.
