SWR REDHEAD Details
Welcome to the party! 2008 marks the twentieth anniversary of a love affair between bassists and the most influential (and most imitated) bass combo amplifier in history – the SWR Redhead. The original Redhead revolutionized bass guitar amplification by combining SWR’s crystal-clear full-range tube preamp with a robust solid-state power platform into a rock solid, yet easily portable 2X10 cabinet. Loaded with two state-of-the-art 10” speakers and a high frequency horn, the Redhead sounded simply phenomenal and offered unprecedented patching options designed to meet the needs of discerning bassists, whether playing live or in the studio. Twenty years later, its features are far more than just relevant – they remain industry standards.
In celebration of this 20th anniversary, SWR once again raises the bar, and introduces the newly redesigned Redhead bass amplifier. Embodying more than just a face lift, the new Redhead design incorporates innovative and attractive new features that will make you fall in love all over again.
