Jim Marshall, July 29, 1923 – April 5, 2012

Start with a Bassman
Separate amp from speakers
Use four 12-inches

Close cabinet back
Add higher-gain pre-amp valves
Post-volume filter

Overdrive sooner
Treble frequencies boosted
Voilà! The Marshall

Townshend, Entwistle
Stacked ’em — the world got louder
Cream, Hendrix echoed

Dozens of models
Followed — famed followers, too
Too many to count

Ideas have lives
As do great sounds and moments
Decay and sustain

Marshall, the amp king
Lived to 11, times 8
Rest in non peace, Jim
