Roger Mayer Concorde+
When I first started designing pedals in 1961 I produced a Treble Booster that was tried and used by my friends including Jimmy Page who then played in local bands. The circuit configuration I used 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 produced in the 1960's of this type of circuit that followed after the time I first designed mine and now I have designed and produced a much more flexible and enhanced version of my early design. The modern clones produced today of the ultra simple 1960 type treble boosters lack in flexibility and in my opinion are of very limited use. The Concorde + however departs from the clones and 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 or 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 oblige. The front panels controls of Drive, Tone and Output control the many tone variations and brings the humble treble booster forward to the future.The Concorde+ comes in a brand new enclosure design with many added extras to help the modern musician. Many players demand a package that is more modern, flexible and pedal board friendly and will welcome the additional features.

Features: The Concorde+ has three outputs, a true hard wire output plus two buffered outputs that can drive long cable lengths with no high frequency loss. These two buffered outputs are identical and are disconnected when the hard wire output is being used. This means that you have a choice for all possible performance or equipment situations whether you feel a true hard wire output or buffered outputs will perform best. In general the low output impedance of the buffer gives a lower noise floor and a more punchy sound but now it's so easy to hear the difference and make a real decision that is based on fact not hype. Connection protocol:It uses the standard negative centre pin connection protocol used by many leading manufacturers. Specifications: 9 volt DC. Regulated output is recommended. Current rating: 50mA or more. |
