Description

Edit description

Step up your pedalboard game with the AMT GR-4, a versatile switch effects pedal designed to streamline your sound. This multifunctional floor passive guitar switchboard allows you to organize and control your favorite pedals and preamps with ease. Featuring a microcontroller-based control system, the GR-4 lets you engage any of your preset combinations with a single touch, offering seamless functionality for both studio and stage.

The GR-4 boasts 4 programmable loops and an additional non-programmable loop, giving you the flexibility to customize your soundscapes. With its fully passive sound path, this pedal ensures your tone remains pure and uncolored. The high-quality relays provide reliable switching, while the shut-off input buffer compensates for the impact of long guitar cables. An external tuner output and a built-in power splitter further enhance its utility, allowing you to feed additional pedals with just one power adapter.

Operating in two distinct modes—fully programmable and independent—the GR-4 adapts to your playing style. In programmable mode, each of the four programs can be set with unique combinations of active loops. Alternatively, the independent mode allows each loop to be toggled on or off independently, offering maximum control over your rig.

Key Features:

4 programmable loops and 1 non-programmable loop
Fully passive sound path with high-quality relay switching
Shut-off input buffer for long cable compensation
External tuner output
Built-in power splitter for powering additional pedals
Two modes of operation: fully programmable and independent
Compatible with 9-12V DC power supply (12V DC power supply included)
