Hey ....well I saw Tim in Carson City , NV back a few months ago and even though he was playing electric guitar he stopped and said " I have brought a guest with me ! " amd he pulled out the Nylon String stlye guitar but it looked as if it had bronze strings . It's not his D-35 or D-28(12) But I think it's a Martin because I saw one just like it in the Martin cat. I have looked every-where and can't find the answer ...do you guys know ??? Cheers !
