The Palmer Saar routes the input signal passively to Amp Out 1, while an active FET switch diverts the signal to Amp Out 2. This occurs without any loss of sound, thanks to the FET input's extremely high impedance. Additionally, Amp Out 2 is isolated from the ground circuit by a transformer, and ground loops can be eliminated using the ground lift switch.

Amp Out 2 delivers a low-impedance, stable signal, enabling longer cable runs without sound degradation. A notable feature is the phase reverse switch for the second output. Since the signal polarity of guitar/bass amplifiers is not standardized, two amps used together may be in-phase or out-of-phase. The latter can result in a noticeably thin sound, which is correctable by engaging the phase reverse switch on the Palmer Saar. This phase reverse function can also serve as a creative sound design tool, offering an out-of-phase sound as an artistic choice.

The Palmer Saar is an uncomplicated yet efficient device that allows for the simultaneous use of two amplifiers, producing an expansive sound without any hum or interference.

Playing your guitar or bass through two amplifiers simultaneously is a fantastic concept, but it often comes with an annoying hum. Fortunately, the Palmer saar Guitar Splitter box can resolve this issue. It effectively separates the ground potentials of the amplifiers, eliminating the ground loop hum that occurs when connecting multiple amps.
