Joe Perry's Marshall Bluesbreaker and Majors
Beneath the U.S. flag is a 1965 Marshall Bluesbreaker with 5881 tubes and four 10" speakers. Foster says it cuts well so they use it if he's not cutting through on a given night. The Marshall Majors beneath it are two 1970 200-watt heads with KT88 tubes. He uses the top one and keeps the bottom as a spare. They find the amp to be a little dark, so it's used in conjunction with an MXR 10-Band EQ to boost the 125 and 1K frequencies.
