Muzzle with very low response

Hi, I am bulding a muzzle and it seems to work ok with the paralel output mod. The problem is that when the effect is on the volume drops drastically.
Also the led seems to change colour but red is always on, it is like change de red to orange.

Also the that4301 ic heats a little. I have some continuity between pins 8/9 wich are GND and pin 10 wich is -9V, is that normal?
 
I turned the led and now it works well, but the pedal is still dropping volume a lot, also the chip after a while starts to heat.

What resistance are you reading between Pin 10 and GND?

I don't believe the 4301 should be getting warm.
 
I had solved the low response, I found 2 resistors swaped.. my bad!
It seems to work well now, but the 4301 IC is still warming a little and had continuity at pins 9 &10 with a reading resistance of -236 with negative tester stick in pin 9 and poisitive in pin 10.
With positive in pin 9 and negative in pin 10 it does not have continuity
