    Hi, everyone, I want to install the original preamp to my friends roscoe, he changed it before and he wants to go back, but I can't find the wiring layout, if someone can help me out, so its the bartolini preamp with volume,blend,mid (pull-push), and stacked bass-treble pots. Thanks!

    you may want to change the title to Bartolini preamp..
    also you probably get a pretty quick and dependable answer if you post this in the Roscoe forum.. Gard and company are extremely helpful

    Only last week I got the 5.2 version which is the same but separate treble and bass.

    I made a quick wiring schematic before installing it!

    On the mid push pull there are also 2 x 47K resistors on the switch - on the right (turning this pic 90 degrees clockwise) from the top to the middle and bottom to middle, middle being where the wiper connects. They are there to prevent switch 'pop' I believe.
