Vise Grip by Seymour Duncan

The Vise Grip by Seymour Duncan is a studio-grade compressor pedal designed to provide exceptional control over dynamics and sustain for guitarists. It features a unique blend knob and a 3-way mini-toggle switch, allowing users to adjust the compression ratio from 1:1 to over 20:1. The pedal offers a maximum compressor gain of +50dB and adjustable attack speed ranging from 2.0ms to 50ms. The input impedance is 1 Megohm, and the output impedance is a maximum of 2.75K ohms. The maximum input level is 3 Vrms, with distortion of less than 0.3% at 300mV RMS output at 1 kHz. The compressor type is a Voltage Controlled Amplifier (VCA).

The Vise Grip can be powered by a 9V battery or a 9V to 18V DC regulated adapter with center pin negative polarity. It has a current consumption of 21mA during operation and 19mA in bypass mode. The pedal is true-bypass and is assembled at the Seymour Duncan Factory in Santa Barbara, California.

The Vise Grip is suitable for a wide range of use-cases, from subtle dynamic adjustments to extreme compression effects. It allows users to control the blend of the original signal with the compressed sound and offers options to adjust the character of the blended signal. The sustain knob determines the duration of notes, while the attack control regulates the speed at which the compressor reacts to the initial pick attack. Additionally, the volume control can be used as a boost while taking advantage of the blend and character controls.

Overall, the Vise Grip by Seymour Duncan provides guitarists with precise control over their sound dynamics, making it suitable for various musical styles and performance settings.
