I grew up with that sound... super deep... pushing UP on everything else..Steppenwolf! The album "Steppenwolf" knocks you out. Hootckie Kootchie Man has the most perfect sound!! Desperation begins with one of the best bass hooks ever. I must add here that digital does not do justice to the original. Who was palying bass when. How was this sound maintained? Was is John Kay's ears? Were these Ricks with flats? Was the bass injected into THE ABC board that's now in the hall of fame?? Info please!!
