Amplified Music Products AMP BH 420 - Jaco Pastorius last head amp

"Jaco used an Acoustic 360 bass amp for most of his career. in all these years, even tho he was offered numerous products no charge from many manufacturers, he always used the 360 in concert. In 1985 he finally found something he liked better while visiting Hartke Systems in New Jersey, the Model BH-420 AMP bass head. It was only after he received the amp that he learned that the same person designed both the Acoustic 360 and the AMP BH-420. That person is my partner here in this business, Russ Allee ... one of the best." - Roger F. Smith - AMP Vice president - 1988
