GIBSON SGs
Cool guitar! Are there "good ones" and "bad ones"? Give me some advice on what sort of SG I should look for OR avoid!
The one I loved was made in the 80's. All the newer ones I picked up didn't feel as good. People versed in guitar lore can recount the rise and fall of Gibson quality but I understand it fell off over the decades.
That said, tone is at least 95% pickups and 5% wood etc. So if you pick up an electric guitar you vibe with as a Gibson it will probably already sound pretty good. Then it's just a question of encountering an object that inspires your hands .

My first nice guitar was 1968 SG Special that I loved. Had a headstock repair but was real solid and just had that wonderful SG P90s sound.
On tour I broke the headstock on my Les Paul and needed a cost effective replacement. Went to GC and grabbed a 2005 "faded" SG for $500, it is was FINE, especially for the money.
Later in life I got a 2010 SG Classic which was the nicest modern version. I had tried others, but that particular one sounded really good. I got it used on craigslist, the owner said it was dead stock.
Went awhile SG-less as any modern SG just didnt feel/sound right to me. A 2018 Standard popped up for the right price and took a gamble, and as far as standards went it was really great. Played good, sounded like how I picture an SG to sound. I dunno if 2018 was a good year or whatever, but that SG was a quality instrument.

I have a 73 SG Special and I hate it. Feels like a toy, G string doesn't stay in tune for more than 3 seconds. Neck is really soft and can be bent all over too easily, making the tuning even worse. Terrible guitar. I need to sell it.

I agree with both answers, FWIW. The fuse is there to protect the big stuff from getting killed due to a failure. So something has gone wrong and you need to figure out what it is. This will mean replacing the fuse and attempting to turn it back on, but with parts removed to try and trace out what the problem is/was. This would, *generally*, mean removing all of the tubes and turn it back on. If the fuse pops, its something internal that has failed, if it doesnt it was a bad tube that caused the fuse to blow initially. Start reinserting preamp tubes and turning it on to see if the fuse blows. If you get all the way through that, start inserting power tubes (in pairs, into the correct sockets) and testing till you find what makes the fuse blow.
This method will likely result in one going through more fuses than they need to. For repeated use without wasting fuses, use a lightbulb limiter to show when the amp is drawing too much current. Google it to build one, very easy.
Also Tyler's point about which fuse will help to further isolate the problem area!
Excellent advice. Clearly written, thank you.
It's the fuse found on the front of the amp near the power and standby switches.
Months later update:
I used the above strategy and concluded fuses were blowing with and without tubes- an ominous sign.
Our bass player finally got it to a tech:" blown caps, needs new inductor eqs, some tubes went bad". I can't help but wonder if this catastrophe is due to poor impedance matching with a cab, a bad speaker cable, or how one bad part could blow up the chain before the fuse shut it down.
It's like when a nice car breaks down: I want answers. I'm thinking it wouldn't be unheard of for him to take the 16ohm output and plug it into our 8ohm cab, or use a guitar cable for a speaker cable.
Dude is thinking of joining the solid state persuasion.

Potentially interested in buying an amp but it's a trek away. Dude sent photos of the internals.
Anything to worry about here? (also, what's the orange stuff on the PCB?)

Caps aren't bulging, so that's good. The crud on the board is dust/dirt/fuzz. You could clean it off with distilled water and let it dry thoroughly before powering it on, if you cared. Doesn't look like enough to cause a problem.

follow up question but do those caps seem like they're....REALLY close to the tubes? Maybe that's camera perspective, IDK but is that normal? I feel like every time I've gone inside an amp chassis or seen gut shots they're at least an inch or so away

So you're co-signing me buying another amp?
Thanks dude!

Yeah, it's not ideal, and probably shortens the service life of the caps. Those are preamp tubes though, so they're not kicking off nearly as much heat as the output tubes are.
Modern caps would be a bit smaller in size given the same value & voltage rating, so the distance would increase a bit if it was recapped. I'd also use 105 C rated caps in these positions, rather than the standard 85 C parts.

If I was going to sell my Moog Prodigy and Rogue and just have one newer Moog, which do you think I should go with? Matriarch? Grandmother? Sub 25?
It's mostly just for messing around at home, and I'm not really much of a keyboard player tbh so I'm trying to slim down the synths I picked up over the last few years.
