1982 Marshall JCM800-2203 Black, Very Good, $1,375.00

Offered for sale; 1982 Marshall JCM800 2203 serial number 05951P. This amp is in very good condition, fully functional, cosmetically there are some nicks and marks here and there showing history of being played and enjoyed.

There was one minor mod. Someone cleanly installed an input directly to the power amp. Maybe he had a Marshall or ADA preamp. Not very useful these days and very easy to restore, we removed the jack and leads to the power amp.

“The all-valve JCM800 2203 is one of the most highly respected 100W Marshall heads in the company's long history. Evolving from the legendary Plexi head, it was one of the first Marshall amps to feature a master volume control. The essence of simplicity, the JCM800 is a one-channel, all-valve amp with no reverb or effects. Its easy control panel, distinctive roar, and larger-than-life edge immediately set the standard by which all other rock amps were judged and it remained the industry benchmark throughout the entire 16 years of its production life.”

Featuring 3-12AX7 pre-amp tubes, 4-6550 output tubes with a solid-state rectifier. The front panel utilizes pre-amp volume, master volume, treble, middle, bass and presence controls.

A common topic of discussion at the time is their use of 6550 output tubes for North America rather than EL34s. The EL34 is used more these days and has a warmer midrange. All things being equal (and they’re not) the 6550 has a wider frequency response less midrange. This, in my opinion makes the amp more aggressive. This is a generalization because there are a bunch of exceptions between tube brands new and NOS. 6550s have a lower & tighter bass response than EL34s. There is nothing foggy/blurred about them at all. Think tight, punchy and lots of headroom. EL34s have more compression and forward midrange presentation. 6550s are just ballsier.

Dispensing screaming classic-rock tones with a solid Marshall pedigree, surprising versatility, and all at what remains a very accessible price on the vintage market. If you say this amp is too loud for the clubs you’re playing in, I say play in a different club. The power and tone of this amp is necessary to life.

Why buy a reissue when you can have an original!

*Please note: we do our best giving descriptions of used pieces. We have found it impossible to describe every mark on an instrument or amp that is not in the "mint" category. Also, what's important to you may not be important to someone else. For example, you may say, "I don't care what it looks like as long as it plays or sounds well." Another person may say, "Body cosmetics are very important to me so tell me about every scratch, nick and blemish." So, please ask the questions that are most important to you. If you ask they will be answered. They are free and there's no limit. Additional photos can also be made available.
