The GigRig QuarterMaster 8 Gold-Contact Relay Switching Pedal

Simple loop switching for your guitar pedals.

TheGigRig QuarterMaster QMX is a compact true bypass loop switcher designed to simplify complex pedalboards while preserving the integrity of your signal path. Built for players who want fast, reliable control over multiple effects without compromising tone, the QMX provides high-quality loop switching in a lightweight and pedalboard-friendly format.

Designed around TheGigRig's low-noise true bypass architecture and OptoKick optical footswitch system, the QMX delivers smooth, silent switching with minimal impact on your core guitar tone. Whether you're building a compact board or managing a larger live rig, it offers a practical way to engage groups of pedals instantly while reducing unnecessary signal chain length.

Available in multiple loop configurations, the QuarterMaster QMX scales easily from simple grab-and-go setups to larger performance systems.

True Bypass Loop Switching

Each loop in the QMX is fully true bypass, allowing pedals to be completely removed from the signal chain when disengaged.

Benefits include: - Reduced signal degradation - Lower noise floor - Cleaner bypass tone - Simpler pedal management - Faster live switching

The compact aluminium enclosure keeps overall pedalboard weight and footprint to a minimum.

OptoKick Silent Switching

The QMX uses TheGigRig's OptoKick optical footswitch system for: - Silent operation - Reliable switching - Reduced mechanical wear - Smooth live performance control

This avoids the loud mechanical clicks associated with many traditional loop switchers.

Flip/Flop Loop Functionality

A standard loop can be configured as a flip/flop loop, allowing instant switching between selected effects while still enabling additional loops simultaneously.

This is particularly useful for: - Multiple delay pedals - Alternate drive channels - Switching between modulation chains - A/B style effect setups

Tuner & Instrument Switching Options

Each QMX includes a tuner jack mod plug which grounds unused return jacks to help reduce: - Noise - Hiss - Radio frequency interference

The loop returns can also function as alternative instrument inputs, making it possible to: - Switch quietly between guitars - Manage multiple instruments from the same pedalboard - Simplify live rig changes
