SO.........I bought this Fender '63 Reissue Reverb unit. By the time it gets to me, it has a few problems O.K., I'm giving the guy the benefit of the doubt that it got bounced around in shipping. Anyway, one of the springs broke off......I'm looking for replacements & I can go with the direct replacement 2-spring tank or for a couple bucks more, get the 3-spring version. My question is....is there a noticeable difference between 2 & 3 springs? It's only a matter of a few dollars difference, so the cost isn't a factor...but is there a major sound difference? I would imagine the 3 spring has a fuller rounder sound, but what the hell do I know???????
