As a L42 fan, Mark used Jaydee along with the Ashley Pangborn which are very Alembic influenced, the Ashley also makes an appearance in the video for 'Lessons in Love'
Mark began using Alembics when they were supporting Steve Winwood in San Franscisco and a rep for Alembic came up to him and asked if they could build him a bass..this was in 1987.
He moved on from them after L42 disbanded in 1994 using a variety of basses including Fender J basses and finally going back to Status which he uses now.
He still has the Alembics..on a histroical note, his basses were the first to have the hyperbright LED's installed.
The two SII's he has are coco bolo and a really nice quilted maple along with some medium scale SI's
