HRM FootSwitch
Most of you have probably already done this but here's a footswitch schematic for an HRM with OD,PAB and MidBoost that lets you link Mid and/or PAB to the OD footswitch.

Relay, linkers and power supply
Here is my slightly different version (showing the PS, and 1 of 3 relays) to do the same with no need for the DPDT switch or resistors. (not trying to upstage you Henry )
BTW - the resistors aren't needed because it works out that the internal resistance of the type of relays I use double as current limiting to keep the LED's happy. May not be the case with other configurations, so beware.

Its the same circuit as mine without the DPDT - I used it beacuase initially I was trying to do it without the diodes. I would make 2 changes to yours, 1. use a 15V zener to compensate for all three relays on at once and the dimming of the LEDs.
2. Put the resistors in - the last thing you need on a gig is for an LED to burn out and have no footswitch. (leave it on for a couple of days straight if you don't believe me).

Re: HRM FootSwitch
Why do you need to footswitch the mid boost?

whe you want it fatter for solos but not on the clean within the same tune.

Re: HRM FootSwitch
I was kidding, the pedal link is sweet!
I generally either have it on or off depending on the guitar I'm playing, but that's just me.
