Marshall 1959 SLP Handwired and Vintage Series Front Panels

Postby **Mats A** » 06 Apr 2015, 01:54

I wonder the Handwired 1959 SLP has JMP on the front panel and the Vintage Series has MKII. I´ve seen the original 1959 SLP with JMP but did it ever have MKII on the front panel? Also the Handwired wich i believe should be a slightly older SLP than the Vintage Series SLP has Volume 1 and Volume 2 while the Vintage Series has High Treble Loudness 1 and Normal Loudness 2 wich i believe is the older way of writing it.

Just having a stab at it with an educated guess is the handwired version is based on the circuitry between 67-69, the vintage series 68-69.. So my guess would those amps issued in 67 had the aesthetics of the handwired and the later amps looked like the vintage series.. I'm sure some of the guys with collections would know more, cue Matt and sigi ;)

Well Pleximaster maybe you know?

1959HW is a replica of a '69 100W amp : JMP-vol1-vol2 is spot on, the SLP is a bit of a pastiche of old Marshalls (with same trannies as 2203x), MKII and Loudness I and II comes from JTM era, I think they did it to have a part they can use also with JTM45 reissue (just adding the "JTM45" logo on the right).

From what Surf wrote and what they said at the factory the HW and SLP have the same transformers.

Are they different amps? I thought they were similar but one was pcb and the other hw?

1959HW = laydown PT
1959SLP = standup PT (smaller than the HW)

different sounds... HW is brighter (and louder) but its the SLP that has a slightly middier tone than the originals IMHO

So the hw is closest to the original?

yes, comparing the HW to an original '69, but it all depends on the plexi tone you are after and how you play it. If you use pedals the tone difference will be a lot less (except loudness, the HW is a beast). If you are searching 70s tones better the used market... a '67 plexi sounds very different from the 2 we are talking about...
but in the end once recorded the differences will be minimal.
Hope it helps

I believe the amps in 69 differed. The HW got if i remember correctly a log pot on the middle control just because when they tested different Plexis for the reissue they thought an amp that had that sounded the best. But that type of pot is not what they usually used in the Plexi at that timme. They were probably out of that pot at the time and used what they had.

I guess amps were not yet made using modern industrial processes back then so components and manufacture were not 100% the same for all amps made... In a way that makes them even mord special... A bit like guitars... Wood quality varies and the ones made traditionnally depend on made them...

I use both of them. Hard to tell the difference between the two.

So i figure they sound the same. Seen that video from the Marshall Factory where he says the HW and the SLP are the same. The components in the HW is just made to look old. The fx loop on the SLP is a good thing.
