This month we chronicle the titans of the tremolo bar, from the brilliant minds who concocted its mechanics – like Paul Bigsby, Floyd Rose, and Ned Steinberger – to the players who hooked us on its intoxicating effects. And what about the other tremolo – the pulsating electrical effect from amps and pedals? Yeah, we delve into that, too. We also interview Dream Theater's John Petrucci and North Mississippi Allstars' Luther Dickinson, plus explore the life and legacy of legendary jazz instructor Ted Greene. For bassists, we visit Warwick's annual Bass Camp to bring you advice and insights from players such as Victor Wooten, Jonas Hellborg, and TM Stevens. Our guitar and bass gear reviews this month include the PRS S2 Custom 24, TC Electronic PolyTune 2, Guild Starfire hollowbody bass, the Hayden Mini Mofo, BearFoot Model G, NS Design CR5 Radius bass, and more.
