Rock: well recorded bass...60s/70s


whatz up with bass on most rock recordings? is it that hard to get a decent bass sound? must be...as most bass sounds are either a)muddy or b)razor thin...however the bass I found on Santana Abraxas is outstanding though...very dimensional...with a reach out and touch quality...any other recordings that might have this quality?

About Hugh Banton of Van Der Graaf Generator from Wikipedia:

"In 1975 he began building a custom organ based on a Hammond but with added electronic oscillators to closely approximate a full pipe organ sound, with bass notes down to 16 Hz played through 24-inch subwoofers."

I am pretty sure this must be the organ used on "Still Life" as I mentioned in an earlier post. Its as clean, low and prominent as anything I have heard on even classical organ recordings. Probably things going on there at very low frequency that only the very best systems could register.
Buy Magical Mystery Tour in Mono by The Beatles. Gobs of bass,listening to.the remaster from the box set. If you don't hear of feel the bass 8n this recording something is off in your analog front end. NUFF SAID.
