I'd like to make a slightly unusual guitar splitter and am looking for advice on the design. I have a '64 Epiphone EA7-P guitar with two outputs (when using a multipin cable), each with their own volume pot. I want to make a cable/breakout box with an output for two amps, controlled by the onboard volume pots on the guitar. Most guitar splitters I have seen use a single buffer amp that feeds two isolation transformers (Geofex, Jensen, etc.).
What would the best approach be here, a buffer for each guitar output feeding a single transformer?
The schematic below shows the guitar to the left and the proposed "splitter" to the right. I stuck a jumper wire in the guitar to fix the terrible problem with the "varitone on steroids" filter network that Gibson put in this thing. The guitar had an anemic output with all tone controls bypassed. The effects of the tone switches were also akin to what a first month engineering student would set, in order to show the instructor that he/she understands how to work a parametric EQ. The tone switches are actually useful now, very subtle.
Modifying the guitar further isn't an option. I realize the linear pot on the reverb send isn't ideal.
