Talk:Marshall Amplification

message: We need to really cut down on the number of sections.  I've added in pertinent information on the JCM 800 series (mysteriously ommited along with the original JMP) and some famous examples of their use.  However, I've boldly cut a great deal of information regarding the technical minutia regarding the specs of the amp series.  If you've played or own a Marshall, you know it's a Sispysian ordeal to describe each and every switch and feature of each amp.  All we need is an encyclopedia worthy description of it's NOTEWORTHY features.  For example, the TSL has three channels that go "clean, crunch, ultra" and the DSL has only two.  We dont' need to know about each "Deep" switch" or individual reverb tank nuance.  We need to know what the company and it's amps are about.  Even the section as edited is frankly too long and too long winded. Mooshimanx 19:52, 1 May 2007 (UTC)
thread_title: Article cleanup

message: Hey guys,
I just started a section on the JCM 2000 series of amplifiers. It would be good if everybody could contribute by chooseing an amplifer series and making a section out of it. I believe that this will make the "Marshall amplifer" article in general more comprehensive

message: It's well known that Yngwie does actually use as many as 31 full stacks. I'd agree that most bands do use dummy cabinets but Yngwie isn't the sort of person to do things by half.

thread_title:  Marshall Stack 

message: There is much POV-ness, coupled with some awkward phrasing in the article. 
Specifically, the mention of much demand for cutting edge and vintage amplifiers. I'd say demand for innovation from Marshall is on the wane, at best. This can be corellated with the general public distaste for the Mode Four, while the Handwired series is garnering tons of praise (and probably selling relatively well). Not to mention the dozen or so smaller companies all vying for the crown of best copy of a Plexi/JTM45/18watt etc etc.
Also, I take issue with the Bluesbreaker being considered Marshall's most famous amplifier- I'd say the Plexi-era stack has far surpassed the Bluesbreaker in visibility to the general public. And surely, sales of JCM-800/900s have far outstripped probably everything they shipped in the entirety of the 1960s.
The circuitry certainly changed from Plexi -> Aluminum. From Marshalls press release for the Handwired amps:
"The so-called 'Plexi' era (late 1965 to July 1969) was named because of the Plexiglas material used on the model 1959's front panel. It ended when the company changed its front panel material from Plexiglas to brushed aluminum. During this relatively short period, many small but often significant circuit changes were made and the majority of them were in response to artists continually asking for the amps to be more aggressive sounding. After exhaustive research tracking the exact timeline of these changes and also finding many untouched examples of them, a pre-July 1969 SL/A head was chosen as being 'the one' to duplicate."
:That doesn't imply a change between Plexi and Ali panel. That implies a change within the Plexi. All of the changes were evolutionary. There is more of a misconception that the so-called 'Plexi-era' came to an abrupt halt when they switched to the aluminium panel. There is as much variation within the Plexi-era as there was between late Plexi and early Aluminium panel amps. The circuit is fairly consistent for non master volume 1959 heads from their first Plexi appearance to 1980. Even the change from handwired to PCB was gradual (if that makes sense). 
I don't know if it was a weird joke, but Dudley Moore worked for Marshall? I'd love to see a citation for this, as it would be news to me.
The history is a little skewed, there were master volume JMP models prior to the JCMs in the very late 70s. Slash, for instance, played an 800, and had a signature model- but the article implies he played a plexi-era amp. In fact, JCM-800s are every bit, if not more relevant than the current JCM-2000 series. I realize the model sections are a work in progress, just wanted to point that out. It's notable that Marshall actually reissued the JCM-800 amps some 15 years after discontinuing them. If that's not testament to their rapid quasi-vintage appeal I don't know what is.
The paragraph about Valvestate amps is criminally POV-ed, and reads like an advertisement. Yeah, no doy a single 12ax7 can last for years- nothing 'revolutionary' about a tube gain stage coupled to a solid state power amp- such designs have been around since at least the mid 70s. Frankly, the AVT amps are pretty much the exclusive domain of beginners and kids, and have a very poor reputation among professional players. I dont think the section should be wiped out, but really rephrased and elaborated on only in proportion with their more notable products.
Thought I'd solicit some feedback before going ahead and editing.

thread_title:  POV, errors and etc comments 

message: Apparently, the Vox Company of Great Britain invented them in 1964 for use by The Beatles on tour - not that the extra power really helped them to be heard over tens of thousands of screaming teenagers, of course. This is referred to in passing in the Wikipedia article on Vox and claims made in both articles need fact-checking for accuracy.PJtP (talk) 05:49, 1 January 2012 (UTC)
replies: text: Some back history. In a Guitar Player Magazine interview with John Entwistle he stated that he was using a 50W Marshall head and a 4x12 cabinet in late 1964/early 1965. He kept the 4x12  Marshall cabinet but in May 1965 he and Townshend both switched to Vox-AC 100 heads (Townshend using a Vox cabinet as well) because, as Entwistle says in the interview, "Vox aleady had one out." And, to support that statement about Vox, in The Beatles' Anthology video George Harrison clearly states that the band had to switch to Vox custom built 100 watt amps early in the Beatlemania years just so that they could try and hear themselves (they still couldn't) But in Harrison's wording he isn't saying Vox invented them... just that they built some specifically for The Beatles to use. This means Vox first started making 100W amps for them around 1964. Both Entwistle and Townshend switched to Marshall 100 watt heads in November 1965. Their switch was to Marshall's JTM100 Super Lead Tremolo heads... 1959 models (Marshall's earliest prototypes of that amp JTM45s rebuilt as 100s) So if The Beatles were given 100W amps and later, as Entwistle stated, he and Pete switched to Vox AC100s because "they had them out" he was being truthful... Vox DID 'have them out'... they had them out for The Beatles. Having them out and inventing them are 2 different claims. The Who are credited with 'the Marshall Stack' in 1965 because they plunked 100W Marshall heads on top of custom 8x12 Marshall speaker cabinets. They didn't 'invent' the 100W head... just the idea of having multiple heads sitting on top of multiple cabinets towering high enough for 8 speakers. And the heads they were given were first built and tested in 1959. Which precedes Vox specifically making 100W amps for the Beatles by about 4-5 years. By early 1967 both Entwisle and Townshend are using Sound City 100W amp heads in England with Pete using Sunn 100W amp heads when touring in the U.S.(probably to save on carting all that gear across the pond). So by this time it looks like just about everyone has no problems with putting out 100W amps for Pete to burn up. But back to his first pairing of Marshall head and custom 8x12 cabs... his 1959 prototype model Marshalls were the amps used. Did Marshall invent them? I am still digging through stacks of old mags/catalogues from the 1960s/70s.But so far I can't find reference anywhere claiming a 100 watt build before 1959.</S>I will keep looking though. Mr Pyles (talk) 06:34, 1 January 2012 (UTC)
replies: text: I can correct myself already.... the 1959, as I thought I was reading in the interview, was not a year at all. Just a model number. Tricky Marshall. I did find another Entwistle interview from just before his death where he contradicts himself about getting the Vox amp and states 'we told Jim Marshall to make 100W heads because no one else made them' Which was clearly incorrect in that interview because, supported by many photos, The Who did use Vox 100W heads before using Marshall 100W Super Leads... 3 1959 JTM45s rebuilt specifically/supposedly by request and first used by both Pete and John in November 1965... which is after The Beatles were given their 100W Vox amps. Lots of interviews with Jim Marshall have him claiming he gave The Who 3 100 watt heads because "they asked for them and no one else made them" But this would not be corect since Paul McCartney got his 100W Vox in 1964 (Lennon and Harrison getting theirs a little while later). More reading to be done to solidify this one. Mr Pyles (talk) 07:03, 1 January 2012 (UTC)
thread_title: Marshall company did not invent the 100-watt guitar amplifier

message: This line can't be correct
In the mid-1970s, Marshall introduced the "master volume" ("MV") series, which was initially called the "JMP",
The JMP amps were avalible in the early 70's without master volume. Some one should change this. Izzy007 21:06, 9 July 2007 (UTC)
replies: text: I agree, this is a far too common assumption and reposted right across the internet. The JMP series reflect a timeframe, not the Master Volume. I personally own a non-master volume SuperLead from 1979 that is a JMP. The front configuration is the same and indeed much of the circuit/chassis is very much like the Plexi and earlier JTMs.  —Preceding unsigned comment added by 78.16.43.176 (talk) 20:16, 26 October 2008 (UTC)

message: This is clearly out of context, and I am trusting to somebody more knowledgeable than me as to wiki editing.
The change from a 6L6 tube to a KT-66 is impossible, without changing the output wattage, all of the Transformers, and the tube biasing networks. I believe that the correct component should be the british KT-88, that with just a small number of circuit routingd can be used in place of the US 6L6 tube. A kt88 is closely related to either a 6L6, or a 6550 (thereabouts). The KT-66 is actually a lower wattage, lower gain tube much more equivalent to the (US naming convention) 6V6.  — Preceding unsigned comment added by Obsoehollerith (talk • contribs) 01:13, 6 April 2012 (UTC)

message: Until we have reliable sources that clarify the status of the Amplification Division, we need to hold off making bold changes to the article. Marshall amps are notable, the overall group probably is not. So it may be that material about the corporation has to go as it would be wrong to turn this article into a marketing vehicle.
