Sound Advice
For a typical late 60s tone keep your amp’s gain light with just a hint of break up. Back then, without the benefit of preamp gain controls, players like Eric Clapton and Jimi Hendrix would max out the volume and EQ on their amps so that a combination of power amp and speaker distortion was achieved – and at truly awe inspiring volume levels. Modelling amp users can of course emulate this without causing an undue breach of the peace. Use fuzz distortion for dirtier solo sounds and dial in spring reverb for ambience.
