Voodoo Lab Amp Selector PRO Isolated Output Switch Blend Programmable with MIDI

Route your guitar signal to multiple amps with perfect clarity and zero noise

Connect to amps, modelers, and your DAW with stunning fidelity Enjoy noise-free, full-bandwidth tone using studio-grade transformers and ground lifts Preserve your tone with transparent buffer and silent switching Balance any setup using independent level controls and selectable phase invert Store and recall user presets instantly via MIDI

Route Your Tone, Recall It Instantly

Common passive ABY boxes load down your pickups, allow ground hum, and make switching noisy. Amp Selector PRO is an active guitar amp switcher that solves all of these problems with four transformer-isolated outputs, letting you send your guitar's signal to multiple destinations without compromise. Run quad amp setups, combine tube amps with modelers and recording inputs, capture DI signals for reamping — whatever your rig demands. Plus, programmable presets and MIDI control let you save your exact routing for instant recall.

Premium Transformers for Superior Sound

Featuring four custom nickel-core transformers, Amp Selector PRO 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 multi-amp 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 

Voodoo Lab Quiet Switching™ — using proprietary JFET and zero-crossing technology — delivers silent operation for smooth transitions, whether you're toggling between two amps or four.

Fix Phase and Balance Easily

When your multi-amp rig is out of phase, it sounds hollow and thin. Amp Selector PRO’s programmable phase invert lets you set polarity on each output to restore your tone. Plus, quickly balance or blend amps with independent level controls.

Programmable Presets with MIDI Control

Using Amp Selector PRO with your MIDI-controlled rig allows you to switch amps along with your other MIDI devices.
