Allright, I've got a lead on snagging a Bartolini HR3.4 wiring assembly, so it makes it far more affordable to go completely Bart in my project. The problem is the actual configuration of the controls are not what I want. This kit has a stacked two-volume control and then the EQ knobs. I've never liked two volume controls, so I haven't bought this set yet. However... it sure seems that the 5.2 A/P or 5.4 A/P sets have what I want, and the only apparent difference would be how the pots are wired for which controls. My burning curiosity in my mind is telling me to ask y'all, whether it is practical to buy this 3.4 preamp kit, use the electronic components which are identical in all of their preamps, and just get the wiring diagram of the 5.2 or 5.4 and buy the right pots to make it work. I've looked for the actual wiring schematics online, to no avail. Does anyone have a better source for me to rewire the HR3.4 to a 5.2? Should I just call up Bart and ask them directly to email me a drawing?
