I opened up my 1975 Bassman 100 the other day just for shits and giggles, and took a few pics. This made me think it would be really cool to see gutshots of different amps that UG users own.

Rules:
1. Don't spam too much, if you have a question or comment go ahead, but other than that don't post unless it is a gutshot.
2. Only post pictures you took yourself. We all know how to google and I don't want this thread full of stock images.
3. Read below.

DISCLAIMER: If you are unsure of how to open up your amp safely DO NOT DO IT. Amplifiers, and most electronics have capacitors in them that can store a charge long after they have been uplugged. If you go poking around and don't know what to avoid you could be electrocuted (that means killed, not shocked.) Also if you are unsure whether or not it will void your warranty, assume it will. I don't want to hear anyone complaining that I made you mess something up or injure yourself...

^Wow, no kidding. Thanks Ming, great additions. This is already shaping up a lot better than I expected.

Edit: Ming, what power tubes are in that Gibson? Those sockets look huge but it may just be the pic.

The Club Royale sounds as good as it looks too. The mids knob is crazy on this amp.
Around 9 o'clock, it is like a Fender. Noon and it's like a Vox. 3 and higher, you are getting into 18 watt Marshall territory.

I run an a/b/y set up. I use an AC15 and the CR, which is set up kind of Fender-ish.

VOX Night Train:





getting a re-tube while its taken apart Pretty neat wiring, its the first time I've had it apart to look at it really.

I'll try to get one of the XXX up later on...just not motivated to take it out of its road case right now I might also have some shots of a B-52 chassis that I built a box for, as well as a modded Valve Jr. If photobucket ever starts working right for me again, I believe they're all on there.

me either....I'd like someone with a mark IV short body post some gutshots I bet that thing is packed!

I think this is a really cool idea. It fun to see the handwired amps. It always seems like they were trying to spell something with the way they place the resistors.

like gregs J-20.

Bah, no time to strip down the Mesa tonight, so I'll keep this thread bumped until then with the Marshall.
1962 BB reissue (I think).

Now that I think about it, I don't actually know what the hell this thing is.
Any Marshall experts around? I've had it since I was younger, and it's just sort of hung around since then...
Clearly some kind of re-issue bluesbreaker in a 2x12 combo, maybe a jtm45 type of circuit?!

EDIT: durrr, now that I actually look at it, it says JMP44.

WTF is that?!

Shows how much I know about Marshalls, right?

And yeah, I just cleaned it up a bit, it hasn't been out of it's chassis for years.

I play it once every, um, I dunno?
So what's up with JMP44 on the board? What's that mean?

Anyway, this thing has been a prime candidate for some mods for a while now, any ideas?
I've never swapped in a turret board for PCB, that's number one on the list, what else do these like? (please speak in Fender-ese, I don't speak brit... )

Dude... could you post a picture of the entire amp please... I was not even aware that wide bodied MkIVs existed.

Hey 311, post some Splawn guts.


I really only have 2 shots and they won't give you what you really want. Erock posted his in the Only Thread for Splawn Amplification.


Rutch - I'd ask al112987, Roc8995, or maybe Gabel.

Actually, I was just trying to see if it was PCB or turret board and if it was PCB was it like Marshall type PCB or Soldano/Fuchs type PCB. Erock's pic cleared that up though.

Depends what you want it to sound like... some common mods on an amp like that

some will mod it to JTM45 spec and take out the tremelo channel and just have the normal/bright channel set up. but yeah, replace the pcb with turret board. unfortunately on the older BB reissues, there isn't enough space to go to KT66s, but 5881s do just fine in that amp.

otherwise, a popular thing to do on the reissues is to replace the OT with something a little closer to vintage spec.

if you want to move the amp itself into a different direction modding a JTM45 into something like a JTM50 or early 1986 model isn't too hard. Increase filtering, shared to split cathode, swap the tube rectifier for a SS plug in, switch to a 50 watter OT and run EL34s. Will give you more of that 50 watt plexi sound.

Maybe in the next couple of days i'll open up my Mark IV to take pictures. Its needed some rewiring/soldering and the fuse has been changed. Should be interesting to compare to that other Mark IV... Even though it was a widebody.

I didn't even know they made widebody Mark IVs. 2x12?

wow figured theres be more Marshall gutshots in this thread, i`d love to see what a 800 or 900 looks like inside. not sure if i wanna start pulling my amp apart, $1000 dollar amp that i can`t replace HAHA

as for that mesa shot, thats really cool looking, but i see now why the amp builder i know hates mesa and calls them SS amps with tubes, get him talking bout mesa or randall and he goes off on this rant HAHA, it`s funny.. he HATES them with a passion, he`s a cool old guy who`s a hand wired purist, he wont even touch my Marshall

Thanks!!!

Right now, it is having a few problems. I've been putting off working on it.

My guitar teacher gave it to me for free. He is in his early 80's and doesn't use it anymore. It was originally a 4x10 combo. He is a very small guy and had a hard time carrying it. So he made it into just a head. Its a shame, but still coo.
#37
I'll post some more pics of the mark IV later as I'm at work right now. Its a 1x12 combo. the only difference between the wide body and the short is that the graphic eq switch and the mid gain/harmonics switch is on the front instead of the back. I believe the short head is 17" long and the wide body is 22".
