Guitar Pass Thru

"Guitar connection convenience for rack effect users"




The Guitar Pass Thru routing rack effect module enables you to plug your guitars into the front of your rack and do all your effects chain cabling in the back.  Optional buffers for long guitar cables are available.



GT modules have nearly all their connections on the rear panel.  You guitar cable needs to find its way to those connections.  For ease of use and setup, it may be more convenient for your guitars to plug into the front of your rack setup.  That's the purpose of the Guitar Pass Thru module.  It routes your guitar signal from the front of the rack to your effects on the back.

There are two configurations.  The standard Guitar Pass Thru is nothing more than three cables from jacks on the front to jacks on the back.  That gives you three paths from the front of the rack to the back, or from the back to the front - it makes no difference. 

The second configuration adds buffering in case you are using long cables from your guitars.  You can choose which of our buffer modules you prefer.  The signal gets buffered on two of the three paths.  The third is unbuffered.  There is a funky constraint due to space.  You must choose both buffers to be BritBuffers, or neither of them to be BritBuffers.  Of course, buffers are directional.  The buffered paths would have to be used from front to rear.  Or we can buffer only one path and leave two unbuffered.  Your choice.  The buffers are always on.  There is no switching.

Both configurations are presently offered only as special 1" wide left wing modules.  Note that the buffer board and power board of the Buffered configuration must fasten to the PCB support of the next module to the right.  Obviously that means you must have a next module to the right.  If you don't, you will need to purchase a separate PCB support.
