I know one thing.
Last saturday, I had a gig. A new sound man ( which we don't usually have ) did the sound during the concert. All he said to me after the show was:
"- hey man, that's how Bass should sound like, I never heard a better Bass Tone than yours, and I have been doing this for a long time."
I was running my Lakland DJ4 through my Little Mark 2 and 104HF cabinet. Nuff said.
Lakland has been my choice since I grabbed one.
I have been getting similar comments on my DJ4 - people used to compliment my playing, but NOT the sound....now I get more "sound" compliments and not as many "playing " compliemnts....hummmmm......
