The JP15 is still available in three finishes. As of 2018 the new finish is Trans Black and comes loaded with matte black hardware. According to NAMM 2018 the JPX, JP12, JP13 and JPXVI are officially discontinued, but the website still lists the JPXVI. Could it be that there was a change of heart, or have they not removed it yet? That, I cannot answer.
Yeah, honestly I felt it was almost overdue. The huge number of JP models was honestly really confusing, and the differences subtle. This really streamlines the product line.
Yeah unfortunately MM discontinued them. It’s sad because some of us would love to have those models with some finish options. I feel the JP13 was very modern looking with that silver finish and chrome hardware. The over the top finishes on the JP15 are too much for my taste.
