Hi to all singletrack guitar and amp afficianados.
I previously posted on a guitar thread, where some wise words were provided re. what I need to look at to have a functioning amp after years of storage.
To expand....I've a Marshall 100w Super Lead amp, and 4x12 cab.
The amp itself is from 1969/1970, based on the serial number and some other t'internet searches. I've had it since the early 1980s (about '83 or '84, 2nd hand when I got it) and its languished in my parents spare room ever since I failed to be bigger and better than EVH, and embarked on a sensible career in engineering instead of becoming a rock idol.
Cab is flat (not angled) tweed cloth fronted, and I'm pretty sure from memory it has Celestion speakers (I'll whip the back off to confirm)
I've decided its just going to be ludicrously raucous as.well space-consumpling, and in all reality I'm not going to be invited to stand in in Judas Priest or Metallica when someone needs a day off.
I'm utterly out of touch with the electrical music equipment world these days.
So tonthe crunch - any words of wisdom.or advice of how / where / what 'avenues' to use (and avoid) to sell, etc.
(Simple searches on the web suggest these could be worth a few shillings (or even the price of a mid range full susser ! In fact even an empty shell of one was up for £750 ! So I'm wanting to avoid being ripped off like someone selling an early Ming dynasty vase for £1.50 at a car boot.
Any advice of how / where / what 'avenues' to use (and avoid) to sell ? E.g. music equipment shops doing bought-and-sold these days ? (The ones I frequented in my yoof are long gone)
1) Don't turn it on if it has been sitting for a while. Get a tech to give it a once over first. Valve amps like to be used and get grumpy if left alone...
2) Ask on the amps section of thefretboard.co.uk for an estimated value. There are some people there that really know there stuff.
Second recommendation for introducing yourself on:
https://www.thefretboard.co.uk/
Ask for opinions on value, but they also have a very active classifieds section that may come in handy later.
There are many scams on Reverb. (I would avoid it, personally).
Many thanks for that.
I've actually checked it works already 🙈 but will heed the advice and probably not do that again !
(I'm aware of the capacitors possibly drying up after all the years. Funnily that in my day job I'm familiar with modern-day thin film ('self healing') capacitors having a capability of fail (not self heal !!) and in the wrong circumstances give off a highly explosive gas, which in confined quarters can be rather bad to be close to).
Back in the day this amp was pretty reliable (despite all the memories of valve radios and TVs always being on the blink) - one of two blown input fuses in the active time I was using it - if the 'on' was 'on' (rather than just in standby or better still fully off) when plugging in to the mains, sometimes the amp's fuse would pop. But otherwise no problems.
Popped in to say the www.the fretboard.com 🙂

Maybe check eBay for sold listing to get an idea on price
Only problem with the fretboard is they all talk about buying all the stuff all the time. I've ended up with loads of stuff when I should have spent the money on time and practicing. Careful you don't sell one thing and end up with tonnes of other stuff
do some research, or rather do some research on the speakers - I bought a cab years ago with 4 green backs celestions in, turns out they were 1960s originals - sold three of them, sold the cab separately and at the time bought a mesa boogie amp and cab, and guitar.

As for reverb, we'll I've never had a problem buying or selling on there. I use it a lot. Just remember they take a fee.
You could set up a demolition business......or go deaf, stick a Rickenbacker through the cab and not write a book. 🙂
Definitely get an amp tech to check it over
If you can't be bothered selling it privately and dealing with that hassle, loads of specialist dealers would buy it from you for a good price. There's a great guy near me that buys from all over the UK and he'll even sell on your behalf and obviously takes a commission but it might be an easier route than dealing with the time wasters on Reverb etc

There's a QA label on the inside with a date of Dec 1969.
Also for the 4x12" cab, speakers and cones all seem original, the stamping code dates to Oct 1968 on all 4 speakers, and cone stamping indicates original cones too.





Time to get myself a 1959 Gibson Les Paul to go with it...

Is the correct answer 🙂
Any signatures inside the cab or head? I believe Jim Marshall used to sign a lot of the 60s ones himself
I have no idea how much that's worth, other than 'alot'..
If you're Manchester or NW based, talk to Richard Henry in Stockport, it's crazy how many people he knows (he facilitated the sale of the Greeny burst to Kirk Hamnett!) and he sells stuff on commission
Interesting thread .... Please continue to keep us updated
...doesn't go up to 11!
Worth about a tenner! 🙂
I can't even begin to imagine how loud it is. The most I've played through was my old Roland JC77 which was solid state but super loud albeit totally clean. A full cranked valve 100w Super Lead is hearing damage stuff!
Looks like the head is a mk1 JMP Super Lead. A quick look on Reverb has a few of these (head only) going from between £2500 to £4500. Yours is at the rattier end of that spectrum, although it might fetch more if it cleans up well.
The Cab looks like a 1982B which is, er, a good one. Here's one on Reverb for £4k.

Bear in mind that A) Reverb asking prices are not sold prices, which can often be far less and B) it's only worth a lot to the right buyer (a Boomer guitar nerd with deep pockets) so selling via an intermediary might work for you.
Anyway, that's a very cool thing. I'd love a go on it!

I've had a look at what the old hand-wireds go for on leboncoin. 1500-3500e depending on condition, yours looks like the lower end but might clean up. I've got a JCM 2000TSL which has the inferior printed circuits that happily haven't gone porous (late serial number so hopefully they won't). Even with the 25W power reduction button pressed it's silly loud.
Get yourself signed up for the Marshall Forum. I sold an old 2x12” cab on there a few years ago. Great advice and a great community.
