I sold my E120 recently (replaced it in its 1X12 SSP cab with a neo Celestion Copperback to cut the weight). I still have my K120 in my other SSP 1X12 cab (plus a D120 in my FYG JG Special Reverb combo, but we needn't consider that speaker now). Both speakers are great choices for Jerry tone. The K120, to me, is perhaps a tad warmer, the E120 perhaps a bit clearer and more immediate. Among the pluses of the E120 is it's virtually impossible to overpower/blow with the guitar amps we typically use. But it is a freaking anchor!

Jerry would be the first to tell us, "I never spent my life copying anyone."
