Possibly New (New-to-me at least) Effect Indicator Idea

I was taking a shower this morning (take a minute to visualize that) and a thought popped into my head.  I'm trying to move away from the crappy 3pdt's I've been buying and want to work with some of those heavy duty 2pdt's I've heard so much about.  I was planning on experimenting with buffered bypass or maybe the millennium bypass and I had another idea.

It's not fully fleshed out but the basis of it is:

Some sort of super basic signal generator going through an opamp gain stage and then to a simple rectifier diode and then an LED to ground.  Then I could configure the stomp switch to switch in or out a gain setting resistor that would boost the sine wave or what ever comes out of the signal generator high enough to turn the LED on or cut it enough to turn the LED off.  Or there could be a bypass mute that grounds both the effect and the signal to the LED in bypass.

This would of course require some experimentation and I doubt it has any benefits over normal bypass circuits but it sounded promising in my head.

Thoughts?

Criticisms?

Look how Scott Swartz implemented the indicator LED in the AD-3208 delay.

The design uses a DPDT bypass switch.

Edit:
The schematic and the board have a slight difference that I don't think matters. The indicator switch (JFET) and the 1N914 connect to "S" not "P".
I just designed a new fuzz circuit! It almost sounds a little different than the last fifty fuzz circuits I designed! ;)
