Interesting he is back using Jaydee basses. The accusations i have read about him over the years, cite him as taking endosements just for the money. But i would doubt if Jaydee, being a small family business would provide any financial incentive to him to use their basses. I presume he is using them for the sound and nostalgia. According to the Jaydee facebook page Mark has a new bass which is a replica of his first Jaydee. Glad you enjoyed the concert.
