I had an old one and loved the sound. I posted this photo on my Facebook page a while back and received these comments:
I loved my old 360 (c.1970)....huge sound--warm and LOUD....great back in the pre-monitor days.
saw Chicago in 1970 at W/S Convention Center..had to have that 360..."Hall of Fame" amp...a tank...but mine never quite sounded like Jaco's (must have been defective)..
Both comments were from players I really admire. Sold it several years back. My buddy John Mergili
www.mergili.com restored the cabinet and amp for me. The preamp sounded killer.
