Or...

Hi,

I'm thinking of changing the stock "VHT Chromeback" in my VHT 1X12 combo.  I have a 335 clone with low-output humbuckers, and I play entirely clean blues. 

The amp sounds very good.  The only thing wrong is that the tone is not very (don't know the right word) complex (?) rich (?).  I don't want anything jangly or sharp/piercing, which is sometimes what people mean by "chime" I think.  Just a little bit of added interest, if possible. 

Who I would sound like if I were 10,000 better: Otis Rush, the three Kings, etc.  Otis Rush sometimes used mini-humbuckers to get a tone that I like (although, obviously, no speaker is going to turn my humbuckers into minis -- I mention this only as a reference).

Do I need a 2X12 to achieve that?
