In my first serious band one of the guys had this model HH cab. We all went to Music Ground near Doncaster to buy some new gear, and the owner opened the shop for us in the evening to try stuff out. We ended up with an HH PA system (200 watt mixer and a pair of Pro 2x12 cabs), an HH 2x12 guitar combo and an HH bass rig ( 100 watt head and this cab).
Seem to remember that although reasonably heavy the cab was quite easy to manoeuvre, and a great design with the clip off front. We used it for everything at some point - bass, keys and guitar, and it sounded fantastic. Think 215BL maybe stood for bass/lead? Anyway, great cab, and GLWTS.
