M-VAVE ABY Line Selector Pedal – True Bypass AB Box Mini Guitar Bass Channel Switch 2026
The M-VAVE ABY is a compact true-bypass line selector pedal that allows guitarists and bassists to switch between two signal paths in A/B mode or split one input into two simultaneous outputs in Y mode. The true-bypass circuit removes the pedal entirely from the signal path when inactive, preserving tone and signal integrity. A clean, reliable routing solution for multi-amp setups and channel switching. True-bypass design for transparent signal when pedal is inactive A/B mode: switch between two separate signal outputs from one input Y mode: split one input to two simultaneous outputs for dual-amp use Mini pedal format for pedalboard-friendly, compact placement Compatible with guitar, bass, and standard instrument-level signals No battery required for passive true-bypass operation
