The Marshall 2204 fame came at a time when the famous amplifier company had recently switched gears from the vintage “Plexi” style heads to the more modern looking JCM style. The first series in this group was the JCM 800, which differed dramatically from the earlier Marshall amps in that it had a much bigger “Marshall” logo and grill cloth along the amp head face, rather than the hard, opaque plexi that adorned the earlier models. (See Musical Instruments Guitars for more information).

But the first 2204 heads and combos were introduced in the 1970s while Marshall was in its JMP phase (pre JCM). Sonically there isn’t much difference between the JMP and JCM 800 versions of this amp – though some purist might disagree, based on subtle nuances. The reality is that the 2204 was pure, raw Marshall tone – the kind of sound the shaped the rock musical landscape for generations.

Rumor has it that Marshall Amplifiers had struck a deal with a new distributor, and thus had the flexibility to change the design. But what is true is that the crazy “new” look of amps like the Marshall 2204 has held strong to this day, as it became the standard design scheme not just for Marshall, but for every other amplifier manufacturer that came along.

Marshall 2204: Tone

The Marshall 2204 has the unique, distinctive Marshall roar that only a full-blown tube amp can create, though you’ll have to crank the master volume up quite a bit to get it. That’s because it was designed to churn tone out of the preamp and power tubes, and without juicing all of them, you’ll be missing out.

One criticism of the 2204 is that it only has one tone, and this is very true. However, it is a great, full, authentic warm tone that sounds great as a roar or even cleaned up a little bit. This is by no means an amplifier for someone who wants crazy versatility, rather it’s the perfect choice for the type of guitarists who know exactly what they want and are unwilling to settle for electronically modulated sounds. This is the real Marshall sound, the type you can’t recreate with stomp boxes or computer programs.

Marshall 2204: Simple

The 2204 is a simple one channel design. There are no effects loops, channel switcher pedals or anything of the sort. This is a one-trick pony that does its trick very, very well.

Marshall did include the customary tone adjustment knobs to personalize the sound, including; Treble, Mids, Bass, Presence, and one knob each to control the output of the master power tubes and the pre amp tubes. It sounds basic by today’s standards, but these simple knobs can hand carve a personalized tone quickly and easily, and you’ll always find new sounds by experimenting with new settings.

Marshall 2204: Value

You can still find plenty of these amplifiers on the open market, and usually at a very affordable price. When you consider the quality of tone you’re getting for the price, it’s hard not to see the Marshall 2204 Guitar Amplifier as one of the best choices available.
