In this video I shape the tone of a cranked 1967 Marshall Bluesbreaker (JTM45) using just to volume pot on the guitar (Gibson Les Paul 1959 Standard Reissue with Wizz pickups). I'm pushing the amp with a treble booster like Clapton did on the Beano album. This amp, believe it or not, does Marshall tones from Clapton to Van Halen and Slash.
