I ordered a 112 extension cab from Jeff Earl at J Designs and just received the finished product. Jeff was extremely patient with my extensive (and I'm sure tedious) decision making process about what woods to use, piping, grille cloth and several other details. He followed my instructions to a "T" and I have to say that I have never seen such impeccable workmanship in a speaker cab.The workmanship is crisp, clean and flawless. I put a Weber 12F150 in it and it sounds incredible with my Fargen BB 30 head. I got the BB in a trade for another head with a fellow TGP-er so this is my first dealing with Jeff. He matched the head cab exactly (which he also happened to build). Both are rock solid. Jeff's integrity as a builder, business man and human being is on par with the best of his peers if not a few notches above. As you can tell, I am one happy camper. It's just that I am so often disappointed with gear that I have custom ordered that I feel the need to give credit where credit is due, especially when my expectations are not only met but exceeded. Once again, thank you Jeff!
