Hi,

"Plexi" is the nickname given to Marshall amp heads model 1959 that have the
clear perspex (a.k.a plexiglass) fascia to the control panel with a gold
backing sheet showing through as opposed to the metal plates of the later
models.

The sound can best be heard on early Free albums. The late great Paul
Kossoff had two stacks running on an A/B switch. One stack was on half
power, the other was on full steam ahead. A forerunner of the dual channel
amp, I guess.

Other notable users of the plexi are Angus Young of AC/DC and Eddie Van
Halen before he went all "5150". A guitar, a lead, a monster tone.

The only problem is that to get that renowned Marshall crunch, the amp has
to be run at or near full power. Have you ever stood in front of a Marshall
stack on full bore? That's why so many of us old timers are going deef, s s
s sonny! ;)

cheers,

Tridders :o)

Thought for the day: Why is it that you can't make other words out of the
word "anagram" ?
