The Kendrick Roughneck is a Texas blues amplifier from Gerald Weber's Kendrick Amplifiers, designed to deliver the raw, cutting tone associated with Stevie Ray Vaughan-style Texas blues. Kendrick amps are hand-built in Texas with careful attention to the vintage American circuit designs that defined the blues-rock tone of the 1950s and 1960s. The Roughneck is favored by blues players for its dynamic response and authentic Texas tone.
