fuzzrite type circuit & low sustain with humbuckers

[soma89]

I know fuzzrite circuits arent known for there sustain but ive noticed that on my humbucker equipped tele, the fuzz sustains for a very short time.
I could even switch to the single coil on the same guitar and hear that same note ring, when i already heard it die with the bucker. Weird.

Anybody else notice this? The circuit i used is one that of  a Conrad fuzz..very similar to a fuzzrite.
