* sound samples coming soon *

A famed late 60's British circuit that was only produced for two years. It just may be the holy grail of low-wattage British combos, providing classic attitude and aggressive growl, but at lower wattage than the larger famous combos. It has developed a cult like following in the past few years and has numerous web sites dedicated to it's circuitry, photos and modifications. The Concord series is for the player who wants good volume, moderate headroom, distortion, grind and punch in a small portable package. Available in Heads and Combo's in 18 and 36 watts, It utilizes EL84/6BQ5 output tubes and an EZ-81 or optional GZ34 tube rectifier. It's a two channel amp with Tremolo or Bass Middle Treble available on the second channel with an optional master volume.
