1019

Hi,
I am looking for some advice /valuation for a JTM45 rig which I have owned for over 40 years and hardly used. I have never had any work done on it and it has not been switched on for over 4 years when it was working perfectly. As far as I am aware all parts are original.

Details:
JTM45 II SER NO: 1019 marstran.com dates it 64/65
(Picture of Ser # 1015 almost identical but with white piping)
There are some cosmetic issues only:
· Missing leather carry handle
· Front panel defaced by a bodged DIY stand alone mixer unit which was in place when purchased.
· Original silver block logo was missing but a very good reproduction was obtained and now in place.

Matching Cab:
4 x 12 Goodman speakers. (Rare)
Brown Bluesbreaker grille cloth (Rare)

May be interested in selling to a good home but would never split the rig (UK)

if I PM you my email address could you email me some more pics of the cab in high res? showing insides and speakers? close ups of the grill material and logo, handles etc? i could give you a valuation but not based on those pics. there are a lot of fakes out there with brown pinstripe grills. cant say ive ever seen an original one before so i am very intrigued.

probably a bass rig if it has the goodmans speakers.

whereabouts in UK are you?

metromutt

WoW, that's some rare amp and cab you have there.

Can you post any more pics of that mixer section, that's the weirdest mod I've ever seen anyone do! and you say this was done before you had it 40years ago!

Value wise the cab looks neat but George will give you his expertise on that and the amp if it weren't modded would be worth thousands but it's really difficult to judge. Your best bet is to get great pics done of both cab and amp and sell on ebay worldwide plus contact a few dealers, who'll probably already be watching ebay or even this ad! imo don't be to quick to sell, just advertise it well and see what comes in.

If you can post pics internally of that mixer section and the circuit that would be brill

george76

get in touch with me via PM, i know some good contacts that can help you out with the finer details, and possibly also help you sell it for a good price if thats what you intend to do.

i wouldnt be too hasty to put it on ebay. most serious buyers for this stuff would run a mile from ebay sellers. too many fakes & fraudsters out there and a lot of unreliable people when it comes to packing safely etc.

also a lot of collectors dont like to buy items that have been exposed for the world to see. dont ask me why.

those are some 'serious vintage' marshall pieces (assuming legit and you really have owned them yourself for 40 years) so be very careful how you go about things.

Wow. Too bad about the mods. But still, wow. You could probably remove that pretty easily, patch up the holes, and at it would look fine. Brown bluesbreaker cabs are very rare, and that looks to be in great shape. But most importantly, how does it sound? If you haven't powered on in four years you should probably take it to a tech to power up slowly, especially if the filter caps are original. Or else the magic smoke might get out.

Rockbert

Because then they can't make lowball offers. Once the owner gets it out there they learn the real value.

metromutt

Are you still out there 1019 ?

Don't know if a dealer or collector has nabbed you yet, but I'm sure Uncle Jim in the big room upstairs would wish you to share some pics of that amp and it's mixer section with masses. Hope you can call back in at least for an update.

1019

Pics for you Metromutt. Big Jim also saw his wonderful creation before he departed.

Many thanks for posting the pics. Did JM make a comment on the mixer?

My guess is that you could increase the value of the rig significantly by having the headbox restored. Given that the holes are drilled in the front face and not the chassis, I would expect you can have this done without leaving any trace of that "damage".

I'm no expert on specific numbers, but have seen far more commonplace heads selling for close to $10,000 USD. I would expect your rig, after repairs with that beautiful cab and the Goodman's could easily approach or exceed $20,000.

However, please DO NOT power up the amp after having let it sit for 4 years. As mentioned before, filter caps don't like that and if you have originals in there, they should be reformed if necessary. Between the filters and the headbox repairs, you would do best to only take your amazing piece of history to only the top craftsmen in their trade. Do not hand over your amp to somebody who is ready to stick a new set of JJ's in there without doing everything in his power to preserve the original components.

Good luck and please let us know how things turn out if you decide to get things restored.

Restore it and sell it to some douchebag collector (probably can't even play an instrument) for $20k.
Buy a YJM100 and spend the remaining $18k on hookers and Krug.

What a Numbnutt to deface such a beautiful example.
Do you have shots of the guts as it is printed on back - Lead but has 2 inputs suggesting a PA.

Without the drilled holes , in that condition if the circuit board is untouched
the Head is worth approx $13,000 with the holes ? $10,000

Cab approx $5000

But to get the fairest price Ebay will attract the bids. Opening it to t Worldwide Market is the Best way to achieve Max $ believe me.

Also it should have KT-66 Valves in there.

the Head is worth approx $13,000 plus , with the holes ? $10,000 plus

Cab approx $5000

But to get the Fairest Price Ebay will attract the bids. Opening it up to a Worldwide Market is the Best way to achieve Max $.... believe me !

Dealers will stitch you up.

metromutt

To be fair '1019' bought the amp like this and according to him in 1972. Judging by the added volume knobs and aging of the jack sockets I'd say this had been done in the late '60's so this amp would of been an standard used marshall and probably worth half maybe less than a new 68 SL!!! so someone probably couldn't afford a new marshall PA amp and converted their old jtm45

Not sure what you mean when you say "printed on back - Lead but has 2 inputs a a PA would. ?

strat59

Sorry (for the double post) and NO inferrence on 1019. I was meaning who ever did that to it way back in the day. I agree as you say they weren't Valuable Vintage pieces back then so mods etc were of no concern to the owners.

*** If you look at the rear White Panel you will see near the Serial # , LEAD
printed on the panel signifying a Lead Amp , but it has 2 x rear inputs that only the PA amps had. All Lead and Bass heads have 1 x input on the rear in that period. My Avatar is Eric Claptons old JTM-45 Block Logo and it is a 2 input PA amp.

Just curious to see some pics of the circuit board if possible to confirm. Anything is possible with Marshall back then but if some pics are avail would be interesting to see.

1019

I have posted a couple of more pictures for interested parties. Although I said in my first post that I had never had any work done on it, I was reminded by an expert that I did have the mains socket replaced in the early 90s. This was a genuine oversight, I have never had anything else done to the circuit or other components since purchasing it in 1971.

Thanks for the pics, it clears up the PA question for strat59

Might be worth deleting that pic of the el34 LEAD chassis you post earlier on it the thread?

george76

Your cab valuation is way off target. Having seen more pics of the cab I am certain it is NOT a marshall cabinet. Chipboard contruction, wrong tolex, tolex cut differently to a normal marshall on the inside. the goodmans speakers have blue chassis consistent with selmer speakers from the period. only the actual badge and grill material appear to be 'right'.

the jury is out on whether or not marshall actually used brown pinstripe. personally i have only seen dodgy music ground examples and MG are known to have contributed to the doyle book (& other publications).

i think that cab is a home build or a converted selmer or something with a marshall badge slapped on it.

metromutt

Never really gave the cab much though, but that sounds like a shocker, chipboard Do you think the logo and cloth are everyday replicas?
Was the OP aware of this? can't see him getting that cab in '71 built like that.

george76

looks like a genuine 60's script logo but has probably just been stuck on there in the late 60's. he said the amp head also had a script logo on it when he first bought the amp in 71.

the grill looks like genuine pinstripe cloth from the 60's, not repro. its just the rest of the cab that is very dubious in my opinion.

there are/were a few versions of the pinstripe cloth. selmer used a blue coloured version, and there is a cream and brown park version. also there is this brown stuff.

the cab looks very selmer to me. or maybe just some oddball british cab maker that is not very well known. if that grill material was readily available in the 60's it could just be a home made cab with a marshall badge on it.

1019

Thank you Metromutt. The picture I posted 26th May showing a lead chasis is NOT my amp. I have no idea how this uploaded. I have attached the picture I intended. When I find a way of deleting the earlier one I will.

Regarding the cabinet, George76 has seen detail pictures, it takes an expert to recognise that things may not be all they seem. There was no intention to mislead on my part (The head however has been confirmed as genuine). One theory that has been put forward (known to George76) is that the cab may have been a Marshall prototype. Inside the cabinet is a label presumably filled in by the cabinet builders. It is known that Jim Marshall did instruct factory workers in the 60's to put labels in their work as a form of quality control (in fact Jim actually confirmed this to me when I met him briefly a few years ago). I have attached a picture of the label, if anyone can provide info on "Ser No 1610 - 80watt - Chad Tony" it would be a great help.

The serial is ballpark correct for a 1965 cab. My 65 cab (grey pinstripe with block logo) is also 4 digits starting with a 1. but is on a small silver badge on the back of the cab. not on a sticker inside.

I think what Jim might have been referring to when you met him was the penciled in signatures that you sometimes find inside cabs. Quite common to see those, Jims own signature crops up from time to time. but they are done in pencil on the inside of the cab, not on a sticker.

Another thing is that closed back marshall 4x12 cabs are not usually painted black inside, only the open back column style PA cabs are usually painted.

make of it what you will, maybe someone else can shed some light on it, but my opinion is that it is not a marshall going from the pics ive seen.

strat59

That label & Board it's stuck to are not period correct. The board is chip board , is that the rear panel ? Builders would sometimes sign inside the cab back in the day with pencil usually on the sides of the cab.

Beautifully clean example that amp !!!
