So, the other day I was playing my PWE EH3 through my oldest 2x12, an EarCandy buzzbomb that I used to love the dickens out of. It has a pair of Guytron BigTone 55 speakers in it. I kept wondering why this amp sounded so bad through it since the BigTone speakers are meant to be in the flavor of a V30, which Ted has said is the speaker he uses most with the EH3. Wondering why this cab, which always used to be my favorite, sounded bad, I proceeded to pull the speakers and make sure the leads were still good, not corroded, etc. Put the speaker back in after everything checked out, checked my DMM to make sure the ohms rating was correct, and the cab still sounded bad. Very buzzy (no pun intended), harsh upper midrange that can't be dialed out, sort of like a really nasty treble response overall. When I compared it to my beat to hell VHT/Fryette Fatbottom with well broken-in P50Es, there was no contest. The VHT cab was far better. I then, on a whim, grabbed a microfiber cloth and cleaned the dust off the paper cones for both speakers. To my surprise, NOW the cab sounds like I remember: punchy, great woody midrange, no annoying frequencies. So, my question to y'all is, would a bunch of dust piled on the cones over the years really have that big of an affect on the tone?
