Dating your marshall amp
Since several models can share one chassis type (for example, the early brown 5G7 Bandmaster, 5G5 Pro and 5G12 Concert), this kind of interpretation is inaccurate.
Post a link of the desired amp on the “Ebay Watch Post”, so we can help analyzing it. I’ll concentrate on “how they sound”, “how they look like” and also “how to tell them apart”. It was made as a head and as a combo (known as the “Bluesbreaker” combo).Many tube amplifiers will have a tube chart within the amp itself.This may also be helpful when dating a vintage tube guitar amplifier.You can end up buying something that is not what you expected or even something that is damaged or modded beyond repair.So, always keep your eyes open for “fishy” deals, look for information, and always ask for high definition photos (especially from the interior of the amps – the circuit, the tubes and transformers) to make sure everything is right.It was basically a copy of the 1959 Fender Bassman. In 1965, the plexiglass faceplates were introduced.This is the reason why Marshalls of this early era (up to 1968) are known as “Plexis”.Resonance and Presence are equipped with master controls.Even though the head and combo both house 28 controls and eight LED switches on their front panels, they're incredibly simple to understand because of the extremely logical layout.Each of the four channels has the usual suspects when it comes to controls - Volume, Bass, Middle, Treble and Gain--accounting for 20 of the 28 controls right away.Take away the four reverb controls and you're only left with 4 Master controls--2 Master Volumes plus Resonance and Presence.
