Dating old marshall amps
This led to the development of the one hundred watt head. For cost reasons Marshall started to use EL34 Power Amp Valves which made the amplifiers even more aggressive.
It also led to the creation of the 4 x 12 inch speaker cabinet. In the 1970s they started to create guitar amplifiers with master volume controls.
Of course, it’s easy to think of Marshall amps starting with the famous stack, but Jim Marshall had been building separate heads and speakers (and later, combo amps) since the early ’60s.
Marshall’s original inspiration was the Fender Bassman, which may have been a difficult amp for the average guitarist to obtain in England in the early ’60s, when the nation was still in the throes of post-World War II rationing (as Dave Marsh wrote in In July, 1960, Marshall, having developed his reputation as a regularly gigging drummer and drum teacher, opened a musical equipment store at 76 Uxbridge Road in the Hanwell section of West London, which would come to be frequented by some of England’s top guitarists.
and Bob’s your uncle; Marshall keeps on supplying its sought-after tube amps to Jones and Crossland for Birmingham and Northern England.
For the first several years of production, most Park amps followed Marshall designs very closely, and the larger heads are therefore comparable to the evolution in Marshall JTM45, plexi, and metal-panel heads from the mid ’60s to the early ’70s.
Along with his shop repairman and an EMI technician they set about developing an amplifier around the Fender Bassman. By using KT66 valves rather than 6L6 for the power amp stage they created a more aggressive sound. Favoured by guitar players such as Eric Clapton it found its way on to some pretty famous recordings.
It started to create a strong demand with guitarists like Pete Townsend of the Who.
The body is a textured, rubberised case somewhere between an amp case and a tyre.We might not expect anyone to give much of a hoot for an amplifier with “Park” on its badge – a brand that has also graced budget-grade solidstate amps from Asia for the past couple of decades – except for the fact that any player or amp collector in the know is hip to the fact that a Park from around 1965 to around 1980 really is just a Marshall by another name, and often one with a nifty twist.This situation has set up the unusual circumstance that the sub-brand Park amps from the golden years, the point-to-point amps made from the mid ’60s until around 1974, often fetch a little more on the vintage market than their Marshall counterparts.There is nothing more impressive at a gig, equipment wise anyway, than a full Marshall Stack. As they were being imported they were extremely expensive, so Jim Marshall set about creating a more affordable guitar amp that would serve up the British guitar players. Marshall started to make more tweaks to their amplifiers. In the early 1960s had a shop in London selling drums and accessories.
They are the most recognisable brand of guitar amp on the planet. Marshall Amps are now based in Bletchley, Milton Keynes, England. After pressure from touring guitarists looking for a particular sound, Jim set about creating his own.
