I'm playing a 100 bucks 1978 Peavey Backstage 30 and it sounds like a JMP Marshall. Insane bang for the buck!! Paul Weller of the Jam used these in the 1970s.
Gear:
1978 Peavey Backstage 30 1x10 combo with the stock CTS Speaker.
2008 Gibson Les Paul R9 with a Seymour Duncan Alnico 2 Pro in the bridge
The Jam 1979 Live
