i prefer seventies tube amps...but i have played a crate blue-voodoo and it was'nt really that bad....why anyone would buy a marshall is beyond me though.
I partially agree with this assessment. Older Marshall amps had excellent build quality, especially the ones made from 1974 to roughly early 1984 until advent of the horizontal input JCM 800 series. These amps featured PCB / Flying lead construction which allowed them a bit more tonal consistancy. The advent of the horizontal inputs also was the advent of the inputs and control pots mounted directly on the PCB, which lessens the roadworthyness of the amps design. Their quality continued to decline further in 1986, when they changed the PSU design that they had used essentially since 1967 to a less robust and cheaper design.
Current designs feature flimsy PCB construction with clipping diodes ( IE a built in fuzzbox) to simulate tube driven high gain, and 12AX7's mounted directly to the cheap PCB. The circuit path is also much more cluttered and much more complex, than the 1959/1987 and 2203/2204 model designs. The tonality of the earlier designs was partly due to the simplicity of the circuit they copied from tweed era Fenders as well as the componentry and the way that it was all laid out in the chassis, coupled with the transformers. --The newer ones have more in common with a cheap VCR as far as componentry and circuit layout/ complexity is concerned.
Marshall does make so called reissues of their old designs, but they are not the same as their old amps, unless one has the cash to shell out on their PTP circuit Hand Wired series.
Marshall has also shifted it's focus from quality tube amplification to budget transistorised gear to cash in on their name. --Their 'MG' series is made in various locations in east Asia. I've seen these manufactured in Korea, China, and even Vietnam.
As a person who has owned 2 Marshall amps, I have to admit that the Celestion speaker/ open back Marshall combo is a horribly matched setup, especially the fairly common 50 watt models. The only Marshall combo that I played through that had decent tone was a 100 watt 4140 that was equipped with red basket McKenzie speakers. --Incedentally, this was also the only Marshall that I played through that sounded good at less than ridiculously loud volumes.
The 50 watt JMP equipped with Celestion 12-65's that I had sounded horrible on it's own, but pretty good into a 4x12 sealed back cabinet. Sadly, like all Marshalls with the exception of the 4140, it only sounded good when it was incredibly loud.
That being said, part of the pricing on Marshall amps in North America has to do with the fact that they are imported from the UK, and hence carry shipment and border entry premiums. --Fender, Mesa, and other popular North American amps command similar price premiums in the UK and EU.
Another part has to do with the supply and demand of the Vintage instrument market for the amps made from 1962 to approximately 1987, with the emphasis on 60's models, primarily on the 1962 to 1968 models with the Plexiglas/Perspex control panel, which are arguably the best sounding amps that Marshall made.
However, if you need an old style Marshall amp, you can either buy a preassembled amp or a DIY kit from
these guys. --Be forwarned though , if you build the amp yourself, you have to hand tune the circuit yourself, and it may never sound exactly like a Marshall.
