Well I've done that. It worked. But then I like using metal can 2N2222As in Muffs. :-) In fact my favourite Muff right now is based on a Skreddy Pink Flesh but with 2N2222As and no clippers on the third gain stage. It's almost a muddy OD at low gain - and incredibly touch responsive. One of the most fun pedals I've built.
I have some 2N1308s and have been thinking of using them to build a similar Muff. It's a bit like a Supa Tone Bender except I leave the clipping diodes off the wrong tranny. :-) And I have used 2N1308s in things like the Red Rooster which calls for Ge. They work but don't sound as fat. Still a good sound though.
I forgot the 2N1308 are GE, I confused them with the 2N1711 that are in the EQD Dirt Transmitter. I am honestly wondering how I am still somewhat sane with all these 2N's around. Anyway, I was asking this question BECAUSE of the 2N1711.
For all NPN GE applications I ordered some Soviet MP38's.
Can confirm about the 2222s in Muffs, I have a Black Russian build with 2222s and D223As that rips. High-gain transistors are usually called for in Muffs but you'd be surprised what you can do with the low-gainers.
Well, I've seen differences I remember when I first started building pedals I tried a BC108C Sunface and I couldnt get it to work right. Last week I found those BC108C's and turns out they have like 600+ Hfe, no wonder it didnt work right.
