here's mine

As there is no true bypass when using 4CM, I am using a Little Lehle to bypass the front end. The M13 is used in scene mode and switches also my amp (Steavens Poundcake Mk3) which has a switchable loop that is also midi controlled.

Ergo I can take the M13 in and out of my signal chain by just hitting a program on it, and have additional flexibility of taking in and out pedals before the amp with the Lehle.

That's pretty cool man!  I've gone a similar route with using external ODs and distortion with my M13, but I don't have anything like the Gig Rig.  So do you control the M13 with the Gig Rig?

Hmmm...why is there no true bypass using 4CM?

Yes, the two boxes on the lower left are my DIY expression pedals.  They are pretty easy to build.  I have both a momentary and a latching (on/off) switch in each box, one mono jack and a 10k ohm reister wired between each switch and the single jack.  All the parts are from Radio Shack.  I plan on rebuilding them with decent enclosures and switches at some point,  Here is a gut shot.....

They were quite inexpensive to build.  The switches were a couple bucks a piece, the jacks were a couple bucks for the two, the resistors were $1 for five and the enclosures were less than $3 each.  And just about any wire will do for the connections.  They took me about ten minutes or so to build.  If you already have an iron you should give it a shot.  I really like mine.  I can even use them for the pitch glide effect.  They work great for kicking up delay feedback levels for controllable self-oscillation stuff.

It is not bother at all.  My expression pedals have two different switches which are wired to the same jack.  One of them is a momentary switch, which is only engaged when it is pressed down, like a tap tempo switch.  The second is an on/off switch.  The wiring in the box is the same for both.  The only difference is the swtich itself.  I bought one of each switch for each box to increase the functionality.

And in practice, yes it is like the heal/toe.  You can set the levels for whatever you like for the on and off positions. In other words, it doesn't have to be all the way on/all the way off.  For example, I use the momentary switches primarily to increase the feedback level of both the Analog w/Mod and LoRes delays.  This gives me the ability to push the delay into self oscillation.  The off position is set to my normal feedback level and the on position is set to about 95%.  I use the latching switches to change speed settings on tremolo/phaser/vibrato effects.  Off is set to a slower speed and on is set to a higher speed.  For one of my tremelo settings the off position is set to about 40% and the on position is set to about 80%.  I also use the momentary switch for pitch gliding.  I set the off position to 0.0 and the on position to 24.  This gives me the two octave rise.  Does that help?
