Big Muff clone frying MAX1044 in another pedal?

[john.hostetter]

Hi eveyone. I recently built Dean's Stereo Tremolo at GGG:
http://www.generalguitargadgets.com/projects/26-tremolo/143-stereo-tremolo

I added a discrete input buffer, pulldown resistors, and changed R3 and R4 to 220k and R9 and R10 to 8k2 for more output volume.

I just got it working and plugged it into my pedal chain. It sounded great, except that when I flipped on my Big Muff clone (located on one channel after the Stereo Tremolo split) it sounded weak and trebley. Thinking that the input buffer in the tremolo was the culprit, I plopped the Big Muff down right in front of the tremolo, just before the signal split. My tremolo immediately stopped working. After fooling with it for an hour, I realized that the MAX1044 was fried. It's back up and running now but I'm afraid to put it in my signal chain.

Is it possible the Big Muff somehow fried the charge pump on the tremolo?
If so, are there any solutions to this?
Output buffer?

I forgot to add: I am daisy chaining my 9v power using a OneSpot power supply.

Thanks for the help!

The only way that the Charge pump would die is if it was over voltaged or something shorted out inside (against the case etc).
It doesn't matter where it is in the chain.

I guess it must be shorting out inside then. Tonight I put it back in the chain and it worked perfectly (regardless of Big Muff placement). When we finished a session I unplugged all of the power sources to my pedals. When I was ready to fire them up again, as I plugged the daisy-chained power source into the tremolo I heard a nasty "frying" noise (I know not how else to describe it...it sounded like a sci-fi zap-gun?) come out of my amp. Needless to say, the pedal didn't work. I am really confused as to why this 1spot is frying my MAX1044s. I even brought my DMM over tonight and tried to detect voltage spiking: NONE.

I'll keep experimenting, I have about 10 MAXs left.

Thanks for your help!
