I got myself a Mark III Combo when I graduated law school. Imbuya cab with the cane grill. Weighed a ton. I later added a matching Thiele cab. I played it for years. Also had the “holy grail” Mark IIC+ head. But when I started playing Alembics, it seemed they just didn’t get along with the Boogies. My Electrum, then Series I, just seemed to sound better through a Fender voiced amp. Eventually sold all my Boogies, including a TA-15.
