Singer/Bassist with Deep voice

Peter Steele of Type O Negative.

Sadly, Peter is dead, but he had a great, very deep voice. Check him out.

 

Jerry Only was fairly deep (not Danzig deep though).

 

Another dead hero: Mark Sandman from the band Morphine.

 

Beck.

 

One of the best singers ever was the late James Dewar from Robin Trower. Not always deep, but he had that underlying depth and gravel.

Robin Trower - A Little Bit Of Sympathy

Not a bass player, but Victor Brox (he was Caiaphas in the Jesus Christ Superstar soundtrack) has a deeper voice.

Tom Araya. lots of bass mids and treble

 

Larry Graham has a nice low baritone.

 

Was lou reed a bassist in Velvet?

 

No, John Cale and Doug Yule played bass in the Velvet Underground and neither had a particularly deep voice, though Cale's voice was rather monotone sounding, in a cool way.

 

+1 on James Dewar too- one of the greatest , most soulful, most underrated blues-rock singers of all time in my book.

 

+ 100000000000

I wish Peter was still alive. TON = great band

 

Also not a bass player, but Dave Gahan from Depeche Mode rocked a baritone, and actually got more melodic with his singing as the group went on. Songs that have what I'm talking about:

Rush, I Feel You, World in my Eyes, It's No Good

 

Peter Steele obviously the go-to for deep voiced bass player...however, if you want to hear power, emotion, tone and melody at near infrasonic levels, you should really listen to Mark Lanegan.
Not a bass player but needs to be heard.

Seriously.

 

+1
Best metal vocals ever!

 

I came here to say the same, he's a huge loss to music IMO

 

Greg Lake has a deeper voice
