Voodoo Lab Amp selector ABY

A Modern ABY Designed for Multi-Amp Rigs

The ABY concept is simple on paper: send your guitar to amp A, amp B, or both. In reality, many passive boxes load down pickups, cut highs, and especially trigger unwanted noise as soon as two amps are put in parallel. The Amp Selector ABY embodies Voodoo Lab's "pro switching" DNA with a premium approach: active circuit, transformer isolation, and correction tools (phase, levels, ground lift) so your multi-destination setup remains as reliable as a simple rig.

Who and In What Contexts Does the Amp Selector ABY Make a Difference?

This pedal is aimed at guitarists (from regular players to pros) who want to exploit a two-amp rig hassle-free: tube amp duos (clean + crunch), wet/dry configurations (effects in parallel), or amp + modeler combinations on stage. In the studio, it becomes a true routing hub to record a direct signal via the Thru output, prepare for reamping, and quickly compare two amplification chains without uncontrolled volume changes.

Controls, Modes, and Design: The "No Compromise" ABY

The Amp Selector ABY offers two isolated amp outputs, each with level control to balance amps of different power or sensitivity, and a dedicated ground lift to eliminate typical ABY setup hum. When the sound becomes hollow or "thin" playing through two amps, the phase inverter instantly restores sum coherence. For routing, you choose between ABY (classic A/B/Y switch), Direct Access (independent activation of each output), or Exclusive (select one output which automatically mutes the other). All powered by a studio-grade buffer (based on a high-fidelity audio op-amp) to drive cables and amp inputs without loss, and switching designed to remain silent during changes.

Sound Quality

This is not about an "effect color," but an essential promise: lose nothing. Thanks to the buffer and nickel-core isolation transformers (permalloy), the signal retains its bandwidth and tactile response, with firm lows and highs that don't fade as the pedalboard grows. The result is a sense of clarity and stability, especially in dual-amp setups, where a standard ABY might add noise and reduce presence. This type of amp selector is also a classic among guitarists building multi-amp rigs and clean stage changes, and Voodoo Lab Amp Selector products are found on pedalboards oriented towards live and studio use.
