Description
Introducing the Lehle 1@3 ABC Box, a versatile companion for any guitarist seeking advanced switching capabilities. This programmable true-bypass switcher, with its efficient design and superior functionality, allows seamless switching between up to three amplifiers.
The Lehle 1@3 ABC Box harnesses the power of gold-plated-contact relays, featuring active pop-and-click suppression for flawless performance. This switcher doesn't just toggle the signal, it also switches the signal ground, effectively preventing hum loops during transitions between outputs A, B, and C.
The Lehle 1@3 ABC Box offers an alternate use for output C as an effect loop for amp B. This feature enables you to exclude any effects you don't currently need from the signal path, enhancing the overall sound quality. An additional perk is the ability to connect a tuner to output A, taking it out of the signal chain.
Another striking feature of this switcher is its programmability. The Lehle 1@3 ABC Box is not just a standalone unit, but can also be programmed and remote controlled using MIDI program change commands. Its slender, TRS format remote socket aids in programming and can be used for direct contact with MIDI controllers or for communication with other SGoS switchers via a stereo patch cable.
Key Features:
- Programmable, true bypass switcher
- Allows seamless switching between up to three amplifiers
- Features gold-plated-contact relays with active pop-and-click suppression
- Can switch signal ground, preventing hum loops
- Can use output C as an alternate effect loop for amp B

How I use my Lehle ABC on stage and for rehearsals.
Back when I use to play with more amps on stage, I wanted to switch between them. First I used a JCM 800 100 watts head for the basics and lead parts and did some additional sounds with a JCM 800 50 watts head so I switched between them with the Lehle A and B. I always used the C for my tuner to tune live on stage without making noise. Lehle is so smooth with the switching thing and very quiet.

At 29:50 in this "Rig Rundown" with Premier Guitar, Mike Hickey, Bonamassa's guitar tech, shows off his pedalboard where the Lehle 1at3 pedal is placed.
In this source you can see a picture of Justin Vernon's pedalboard which this item is placed at.
*Because I’m using three amps, I got this switcher just before we came out on tour. * The fact that it’s a button switch means you can kick in the third or second amp and I think that this will be very practical in the future tours with new songs in the mix. This P-Split has a phase switch, which for some reason the 1AT3 doesn’t, so it’s essentially just to keep the Bassman in phase.
There is a Lehle 1@3 ABC Box at Björn Gelotte rig, as we can at 3:22 in this video of TC Electronic.

Chuck Garvey of moe. Used a Lehle ABC switching system with his multiple amp rig setup that he used during the Moe. 25th anniversary tour.
Juanma uses this amp selector/switcher to send the guitar signal to a dry amp, through his board to another amp, and to the tuner. Juanma explains the pedalboard he usually used in this radio/internet show called ''Masterclass 6x3'' by Sergio Bustamante in Radio 3, the spanish public music radio.
