Einstein Footswitching Modes - Jack and Wire Gauge Question

[davenotes]

I'm trying to execute what I understand is a relatively simple mod to allow me to footswitch between modes on Channel 1. I want to make sure I'm using the right input jack type and right wire gauge before I solder:

1. Stereo Input Jack: I am planning to drill a new stereo input jack into the back of the amp next to the Channel / Master input jack. The jack hardware that I plan to use is the S-H501-PC-S ... it's a stereo jack, metal nut, CLIFF, 6 PC MOUNT FOR MARSHALL pictured below. If anyone knows if this won't work please let me know. I decided not to use one of my existing speaker output jacks for fear of breaking something and also want to leave that jack available.

2. Wire Gauge: I'm planning to use 3 separate lead wires that are each color coded. 22 gauge, solid tinned copper, pictured below. They look fairly thin, but I think they would work. I saw one picture of someone's mod that used a very thick black wire that had 3 legs inside of it. I found one at a computer supply store that had 8 thin legs inside it, pictured below. Wondering what direction I should go.

Any help / thoughts?

I would use a midi jack instead and run two wires from the toggle, one supply (12V off a relay), ground and also one off the channel switch.
This way you could have a pedal which switches almost everything (modes, channel) without the need of an additional power supply by using just a standard midi cable.
Don't worry about the wire diameter. It doesn't matter. Super low currents and voltage here . . .

Thanks,

Follow-up Question on Traditional Jack Mod: So if I were to go the simple route and just use my "master" jack in the back to switch between modes, is there a recommended way to break the contacts between the green board and the gold jack contact flaps? Also where do I solder the third leg of my wire if there are only two gold jack contact flaps and not three?

Follow-up Question on Midi Jack Mod: It doesn't seem a basic 5 pin Midi jack would work for everything including channel, master, reverb switching, but I'm guessing I would need like an 8+ midi jack. I'm guessing that PIN #1 should be connected to the power 12 V relay and then the ground be touched to the amp case for the ground?

Forgive me for my basic questions ... i'm an amp tech noob. Wondering if Diezel has tutorials on how to do either of these mods in a recommended fashion where I can get all my questions answered. The website only talks more about biasing for different tubes. Any help?

Well, either you run multiple cables or create one yourself. Using a midi-5-PIN plus a stereo should solve your dilemma - or just buy a midi pedal and a control unit from axess electronics, thats the most simplee solution.
I'd stay away from modding the existing switching jacks on the PCB. Too much hassle.
