Marshall JMP50 turret board
« on: June 11, 2010, 05:06:59 pm »
I had a customer bring in a 70's JMP50 Bass version that someone had done a hack job on trying to convert it to the lead version and I laid out and installed a new turret board to drop in place of the original pcb.  I thought I would post the PDF file of the board and mask for anyone who wants to download it but the file limitations of the board prevent that.  So, attached is a somewhat blurry gif file.  The extra row of turrets on the rectifier end are for the different PT taps which are in the 70's model.  If anyone is interested in the PDF file which can be printed to scale  a little easier, email me.

 The dimensions of the board are 3 1/8" x 12"  The 6 red holes line up with the 70's model stand off bolts.

Guides on your quest for tone.
 Oh yeah, and I'm usually just kidding so don't take me too seriously.
