Voodoo lab ABY Amp Selector

Common passive ABY boxes overload your pickups, generate ground loops and are noisy. The ABY Amp Selector is a high-end active ABY guitar pedal that solves all these problems with two transformer-isolated outputs, allowing you to route your signal to multiple destinations simultaneously, without compromise. Use two amps, combine tube amps and modeling, and capture DI signals for reamping - whatever your rig configuration.

High-grade transformers for superior clarity and sound quality
Featuring custom permalloy transformers with 80% nickel cores, the ABY Amp Selector delivers exceptional frequency response and clarity that standard transformers can't match. The high-inductance design enhances your sound by preserving bass and high-frequency detail, for a full, dynamic rendering. Independent ground switches on each output allow you to instantly eliminate unwanted noise typical of ABY configurations.

Preserve the purity of your sound
Using multiple amps with passive switches or long cables can alter the treble and presence of your signal. The ABY Amp Selector's studio-quality buffer is built around the Texas Instruments LME49720, an ultra-low distortion, near-zero noise op-amp, guaranteeing exceptional signal clarity for pure sound from input to output.

Switching without noise
Most ABY pedals use noisy mechanical relays that produce clicks and pops when changing channels. Voodoo Lab's Quiet Switching technology ensures silent operation for smooth, professional transitions.

Phase correction and easy level adjustment
If your two-amp setup sounds hollow and thin, it's out of phase. Activate the phase inverter to correct the polarity and restore your sound. Independent level controls let you instantly balance volume between different amps or models.

Three modes to suit every configuration
Use ABY mode for classic A/B/Y switching, Direct Access mode to independently control each output (one, both or none), or Exclusive mode where selecting one output automatically deactivates the other.
