The amp behind the PRS HX 100 (later renamed the HDRX 100) is thought to be one of the touring Marshalls Jimi Hendrix played live at Woodstock '69 — serial SL/A 10045.
I was fortunate enough to get my hands on an HX100 before the rebrand to the HDRX100. The head was captured full tilt into a Two Notes Torpedo Captor X loadbox and Profiled using a handful of custom cab IRs. All clips were recorded raw using a MIM Strat.
Let me know what you think. If you're interested, you can pick up the PRS HX100 Kemper Pack at my site for $2.99.
