BOSS KATANA Head vs Marshall 2203 JMP

In this test I enlisted the skills of Mr Andro Martinez (Gang of Brothers) to compare a BOSS Katana 100 Head with his late 1970’s Marshall 2203 JMP amp, both into the same cab. The test was recorded using just an iPhone, to try and show the sound and vibe in the room with no audio post production. AMP1: Marshall 2203 Master Volume JMP AMP2: BOSS Katana 100 (CRUNCH mode) CAB: 1980’s Marshall 1960A cab w/Celestion G12M Blackback speakers. Recorded on: iPhone 6S (internal mic)
