Motorola HEP 53 Fuzz

A friend of mine is a parts junky like I am, and he hooked me up with a few old school transistors for me to goof around with in my fuzz pedal. I'm still looking for pinouts for one group, but out of the others, I really liked the sound of the Motorola HEP 53. I can't put a date on this transistor, much to my chagrin — but it looks like it was something bought in the early 80s. With a maximum hFE of 85 (though I'm getting around 30, measured), it's a pretty good candidate for a classic fuzz sound — and here's a totally lousy recording (the SM58 is hanging in front of the speaker because I was too lazy to go out and get my mic stand). This is my Les Paul, bridge pickup, volume max, tone rolled all the way out:
