THIS IS IT! The amp that defines classic rock ﾖ the Marshall 100 Watt Super Lead Plexiglas head of the late ﾒ60s, re-issued in all its glory. To ensure tonal authenticity we searched for an amp from this period that epitomised this model. We gave this amp to our guitar playing research & development experts and they developed a replica that was so exact we couldnﾒt tell them apart. As previously mentioned, the only modern concession made was to add a tonally transparent Series Effects Loop with a true bypass switching option for the purist.
