In this video I compare 5 Booster Pedals from BSM Pedals. I'm playing them through a 1963 Vox AC30 Head and a 1968 Marshall 4x12 model 1982A. I'm using both Fender Strat (1973) and Gibson Les Paul Custom (2010). The pedals are:
BSM RM - Based on 1965-1969 Dallas Rangemaster for a Clapton or Tony Iommi tone.
BSM DM-T - Based on unspecified late 1960s Germanium booster. Sounds like Brian May to me.
BSM RW-F - Inspired by Ron Woods early 70s Humbucker tone
BSM RPA - Based on Ritchie Blackmore's tone around 1974 on for instance on California jam where he got extra push from the preamp in the Aiwa tape recorder he used for the echo.
BSM Model Studio 75 - Based on the guitar tone on Rainbow's first album.
