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 Tone 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.

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.
