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 (not included) 9VDC Adapter (we recommend the Boss PSA-100/110/120/220/230 or 240 depending on your local AC supply voltage) 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 a black anodized coating and laser-engraved printing.

User Manual (Rev. 4)
DO NOT USE A COMPACT SWITCHING OR SWITCHMODE POWER ADAPTER (SUCH AS THE BOSS PSA-120S, THE ONE SPOT, THE POWER ALL AND SIMILAR MODELS) TO POWER THE BS2 BECAUSE THEY HAVE BEEN KNOWN TO DAMAGE IT. A SUITABLE ALTERNATIVE TO THE ADAPTER THAT WE RECOMMEND IS A HIGH QUALITY POWER SUPPLY SUCH AS THE BBE SUPA-CHARGER OR THE VOODOO LAB PEDAL POWER II.
