⭕ 1966-67 Marshall Bluesbreaker 2ND Series Logo.made famous by Eric Clapton when he played with John Mayall and the Bluesbreakers.Very versatile amp, and that is why they are so great for studio or stage. From awesome blues-rock, violin tones, and the room shaking low end of a vintage plexi, to the shimmering and harmonically articulate clean tones.Bluebreakers take pedals (or echoplexes) well and with its power is capable of a lot of heavy high gain modern tones as well, with or without pedals and effects.Big enough for any gig, small enough to rock your home studioThe chassis looks great, original transformers, one has a code, looks like 1202 113 (or 118?) and I cannot find a code on the other old tranny.Original choke in fine shape.The white panel says Super Tremolo, and the amp is designated as a LEAD amp (not a bass or PA).Serial no. 67XX.It has great old KT-66 power tubes, one (1) Mullard ECC83/12AX7 preamp tube, one (1) rare Winged C ECC83 pre-amp tube, one (1) Sovtek pre-amp tube, one (1) Edicron ECC83 pre-amp tube, and Sovtek 5AR4 rectifier tube. European 3 prong cord. Of course you select different voltage from 105-115, 200-210, 220-230, 240-250 volts; I like both, sounds fantastic either way.
