I lstened to a pretty good comparison of the stock speaker vs 4 other 10 inch eminmence speakers including the RC and the copperhead on the Gear page, and the stock speaker sounded best to me and 4 or 5 other people who responded. I saw a vid of Don Anderson doing The thrill is gone. I downloaded a backing track and fired up the SCXD. Voice 13, reverb/delay, treble 0 and bass 10. Used my LP standard, 335 and GT, even tried a CV50s Strat. All sounded amazing.
Of course it might be my aging ears. LOL.
Every time I fire this thing up it just amazes me. Oh and I tried a little boost from my Fulldrive II by Fulltone and it kicked ***.
Not sure now what to do about a speaker swap.
