Roger Mayer Concorde and Treble Booster

The Concorde+ Treble Booster, housed in the new Vision Series enclosure, uses both silicon and germanium transistors in a unique configuration to obtain the best tone qualities from the marriage. When Roger first started designing pedals in 1961 he produced a treble booster that was tried and used by many of his friends, including Jimmy Page, who played in local bands. The circuit configuration was a standard textbook example but required careful attention to biasing and selection of transistors to obtain the best from this simple circuit. There were many subsequent commercial versions of this type of circuit produced in the sixties that were not available at the time Roger first designed his and today Roger's been asked to produce a more flexible version of his early design. The modern clones of the ultra simple treble boosters lack in flexibility and Roger believes they are of very limited use. The Concorde+ uses a unique approach of combining a low noise class A silicon drive circuit with passive tone shaping to drive a fully optimised germanium treble booster. This results in giving the simple circuit new life and explores its sonic boundaries to the maximum. It is now possible to add drive and distortion with EQ before the treble booster section. It is also possible to set the silicon drive section to drive the treble booster section much harder than any guitar pickup could ever do without any added distortion but with the added feature of having EQ prior to the treble booster. So if you want the qualities of soft germanium type distortion overload characteristics that this circuit will produce or you want to explore the more radical germanium distortion possibilities the Concorde+ will deliver. The front panel controls of DRIVE, TONE and OUTPUT control the many tonal variations that help bring the humble treble booster forward to the future.
Works and sounds perfect. Super clean condition.
