This one will give me 1 instrument INPUT = 2 amp OUT / 1 tuner OUT
3 total OUT, but only 2 are dedicated to feeding amps.

The BS2 Guitar Audio Buffer/Splitter prevents the loss of (1) signal level (2) high end frequency response (3) low end punch that is caused by cable capacitance and poorly designed input stage/circuitry of some effect pedals.
Our buffer circuit is a very high quality Op-Amp based design that is both low-noise and MUSICAL, don’t let other’s try to deceive you, nothing is transparent !!!
Three outputs allow a single guitar signal to feed a tuner and two amplifiers without any signal loss and/or tonal degradation.
Two of the three outputs are connected in parallel and the third is Transformer Isolated to prevent Ground Loop Hum/Noise when driving two amplifiers.
The Transformer Isolated output is equipped with a Phase Reverse switch to prevent phase cancellation problems from occurring when driving two amplifiers.
Powered by a 9VDC Adapter (we recommend the Boss PSA Series - not included) with a 5.5mm/2.1mm barrel connector.
Housed in a compact (4.40" x 2.40" x 1.30") and rugged 0.064" thick aluminum enclosure for years of reliable use and performance.
Brushed finish with black anodize coating and laser-engraved printing.
