The Framptone Amp Switcher will allow you to switch between or combine two (2) amplifiers without the common problems encountered when using an A/B type box. Such problems include ground loops, instrument loading/signal loss, switching noise, and phasing. The Framptone Amp Switcher solves ALL of these problems in the following manner:

Ground Loops- When splitting an instrument signal to or switching between multiple amplifiers, it is common to have a loud, ground hum. In the Framptone Amp Switcher, this is solved by the use of the highest quality isolation transformer, which electronically isolates the ground between amplifiers.

Instrument Loading/Signal Loss- When splitting an instrument signal to multiple amplifiers, sound quality is lost because the high impedance output of guitars and basses is not suited to feed more than one high impedance amplifier input. The Framptone Amp Switcher’s instrument input is fed through a custom-designed buffer circuit which converts the instrument input to a low impedance signal allowing the instrument signal to be fed to many amplifiers simultaneously without suffering ANY signal loss or degradation.

Switching Noise- The Framptone Amp Switcher uses durable, soft-touch momentary switches for click-less, noise-free switching.

Phasing- When combining two amplifiers, occasionally they can be “out of phase” with each other causing a thin, bright sound. The Framptone Amp Switcher is equipped with a phase-reversal switch, accessed right above the battery holder inside the unit. The ‘N’ side is for normal phase (most applications) and the ‘R’ side will reverse the phase of amplifier B, immediately eliminating the “out of phase” condition.

Programmable Modes- The Framptone Amp Switcher is now equipped with two (2) programmable options which can be preset to fit your musical needs. The first is the ability to change the flashing “Last Amp On” feature to a solid, non-flashing LED. The second option provides the ability to mute both amps (silent guitar changes, silent tuning, etc.) instead of combining them. Simply remove the bottom cover of the unit and set the labeled dip switches (located under battery holder on circuit board) accordingly.

This great switcher is lightly used and works great. It ships the next day with the included power supply.
