Palmer Audio Tools PGA03 Y-Box Isolated Guitar Splitter

"When I run my guitar into two amps simultaneously, I always get a loud hum". This is a rather common problem, often discussed in the technology section of relevant industry magazines. The Palmer Y box is the solution. Converting the hi-Z guitar signal, the FET input circuitry also drives a transformer which routes the ungrounded signal to the output to eliminate ground loop hum. 9V battery operation is recommended.   The PGA03 Y-box can also be used as a line driver for long cable runs. Also, the PGA03 features a phase reverse switch.
