Ive been looking around for a another Weissenborn guitar. After playing one at Westwood music in Los Angeles, I by no doubt wanted to get an Iseman Weissenborn. I talked with Mark and Matt a few times on the phone and they nailed it. I love my all Hawaiian Koa Iseman. The craftsmanship is very clean and I had no complaints with their work. Can I say CLEAN all the way around.They were the very nice to talk with and were very patient with me. It sounds so sweet and warm. The koa is amazing!! Aloha guys for your time and building my dream guitar.
