Making a jack jig for Fender amps.

If you've ever tried to replace the jacks on a Fender amplifier you know that it's tight working inside  that area particularly next to the chassis wall.

Here's a handy time saver that makes me wonder why I didn't do this earlier.

Get yourself a flat piece of aluminum. I used the cover for a discarded project box. Bend a right angle in it for stability's sake.

Lay out and drill 2 5/16 diameter holes that are 7/8 center to center.

Put your two new jacks in as shown. Install and solder the two 68k resistors and the 1 meg resistor as shown in my shop sketch.

Install and go have a coffee with all the time you just saved.
