You might have a better chance of getting this upvoted if you included some more information about it, such as why somebody might want to build this over one of the other dozens of Muff derivatives — otherwise it's JAM *Just another Muff.

Looks to me like you could build this on just about any Muff board by McGyvering the tone section to come after the recovery section.
Nonetheless, personally, I'd like to see The Sweet turned into a PCB, because I'd like to build a Bass Sweet without the circuit wrangling on a stock Muff board and also don't want to resort to an etch, perf or vero.
(Bass Sweet has same layout but different component values.)
Frantone - The Sweet
?I hear some people have found one at DIY Musikding but I can't. Any help? I can supply gut shots if people are intrested!

I don't think anyone has found anything on the FS25444 - it is absolutely unique to this pedal (or is a remarked something else).
Tagboard effects suggests it looks like the 2N5133 or ME4003 as it is in the old TO106 case style - so I was thinking about using NOS 2N5133
Effects Layouts suggests rounding up the usual suspects in place of the FS (whatever the heck): 2N5088, MPSA18, BC549C, etc.

Adjust to taste is always best, anyway.

Bumping an old thread for more Frantone goodness. Reading through the FSB post above it looks like folks may have found a sweet (sorry, pun intended) spot with a low-gain NPN option in Q4. The comments mentioned a 2N3563 at ~70 hfe but maybe a 2N3903 would be a good alternative?

I'll definitely give that a try... I've got another etched board lying around... and something in the pipeline as well...

Dunno - it might be a rebadged NTE...
Only reference to an FS25444 transistor I've seen is on a couple of aviation sites, but there was no data sheet.
More likely that the NTE is a rebadged FS
Doubtful, but maybe. The NTE2544 has an hfe of 1k-2k! Could push a 8 inch speaker with that thing
I doubt it matters much. It's just makeup gain for the tone stack anyway.
