The C8R is the little gem in the Jensen Vintage series. It delivers a solid compact tone that defies its size. Extremely versatile, it finds application in small home and student amplifiers; but with a microphone in front, it is capable of transferring on tape some of the biggest tones ever. Not by chance, the vintage Fender® Champ® amplifiers produced with the C8R speaker are treasured by many players as a great studio tool.
