I have two questions regarding an old Acoustic 370 bass amp head and the new Acoustic B600H bass amp head. I own an Acoustic 370 head I bought new in 1975. It is in need of repair but I cannot find anybody who can fix it or get compatible parts. It has lots of power but the sound is very distorted. Does anybody know where I could possibly get parts for this amp? Otherwise, I would possibly be interested in selling it for parts if somebody needs one. I recently tried out the new Acoustic B600H head and I must say I was quite impressed with it. It actually sounded better than the old Acoustic heads and even better than any of the new Ampeg or other heads I tried out. Does anybody had positive experiences with this head? I heard they are made in Asia but many electronics are now and I was wondering how the quality is. They do have a 3 year warranty.
