Looks like SGD, transistor facing me pins down. I didn't see much, must be a general purpose Fet These came out of some Multi effect units I've been repairing, cheep switches are cool!!!
Looked like a well designed multi circuit box, except the 'fall apart' switches I think 3 of 5 of these multi effect units [a friend of mine got in on a bulk order] had a failed switch within the first 6 mo. Thanks for the help guys! You'll find those in the buffer sections of a lot of older Boss pedals as well as in the switching circuitry. Decent enough FET, I only keep a stock for repairing Boss and Ibanez pedals cos it's easier with a straight swap on the pinout.
I bought some many years ago to built and experiment with Boss type switching instead of true bypass. When I noticed they were also used as buffers, I began to use them in preamp circuits and found they had good specs. Having some FETs with different pinouts is what started me on using a 4 pins socket in my circuits to be able to use any pinout.
Fewer broken transistor legs? I thought I might want to try some of the found k30a's SMF 2.
