I own the head & combo versions of both the Heartbreaker & the DC 10. [/b]Both amps have excellent sounds. The HB has the option of changing power tubes, EL 34's, 6V6's and 6L6's. Silicon or Tube rectifiers,tweed power, either channel can be clean or dirty, the Bold/Curvaceous switch is a nice adjustment. All of these things really help shape the sound and versatility of the HB, it's really great for Blues/ Jazz , Classic Rock , R&B, Funk & Country. Not a Hi Gain Firebreather. The DC 10 has a really nice aggressive Lead channel, it does the "Marshall thing" much better than a Marshall. In fact I sold my modded Marshalls after owning the DC 10 for a while...didn't need them anymore. I really like the DC 10's clean channel it's as clean a Fender, it has a gain boost that's great for edgier clean tones, . DC 10 does it all Hard Rock , Metal , Blues / Jazz , Country, R&B...you name it , and does it well! It's my favorite amp, if I could only have 1 amp, it would be the DC 10 (I have over 60 amps)! I hope that this helps you. 8) 8) 8)
