This is a hand-soldered point-to-point Marshall Super Lead 50W guitar head assembled into a Marshall 1987S Super Lead re-issue chassis and case. In 1988 the 1959 and 1987 Super Lead amps were reissued for the first time. These first reissues were manufactured only in 1988. The parts are from Metropoulos Amplification and I did the soldering by myself "with a little help from my friends". Special thanks to Sam Vilo, Mikko Kankaanpää and Matti Kari for their advice and support.
