Voodoo Labs AS-ABY Amp Selector ABY Isolated Output Switch/Blend

Send Your Sound Anywhere

Common passive ABY boxes load down your pickups, allow ground hum, and make switching noisy. Amp Selector ABY is an active guitar ABY pedal that solves all of these problems with two transformer-isolated outputs, letting you route to multiple destinations without compromise. Run dual amps, combine tube amps and modelers, and capture DI signals for reamping whatever your rig demands.

Premium Transformers for Superior Tone

Featuring custom nickel-core transformers, Amp Selector ABY delivers exceptional frequency response and clarity that standard transformers can’t match. The high-inductance permalloy design enhances your tone, preserving low-end punch and high-frequency detail, so your sound stays full and dynamic. Plus, independent ground lift switches on each output let you instantly kill the gnarly noise that’s common with ABY setups.

Keep Your Tone Pure

Running multiple amps with passive switchers or long cables robs your signal of highs and presence. Amp Selector PRO’s studio-quality buffer is built around the Texas Instruments LME49720, an elite audio op-amp with vanishingly low noise and exceptional clarity so your tone stays pure from input to output.

Switch Without Pop

Most ABY pedals use noisy mechanical switches that click and pop. Voodoo Lab Quiet Switching using proprietary JFET and zero-crossing technology delivers silent operation for smooth transitions.

Fix Phase and Balance Easily

When your two-amp rig is out of phase, it sounds hollow and thin. Selectable phase invert lets you switch polarity to restore your tone. Plus, quickly balance or blend amps with independent level controls.

Select Amps Your Way

Amp Selector ABY lets you choose between three modes. A/B/Y for classic switch and blend operation, Direct Access for dead simple independent on/off control of each output, or Exclusive mode where a single button press switches from one amp to the other.
