Back in the day in my teens I was listening to Joe Pass and Wes Montgomery a lot; before that I was listening to what I would call now the more 'simple' jazz players (but still very valid), like Barney Kessell or Johnny Smith; I learnt a lot of voicings from Johnny Smith records. Now, I listen to the old blues players; that's what you'd hear in my house if there was music on. It would be Albert Collins or Albert King.
