You're better served getting the proper "2 spring" (actually a 4-spring) tank. But if ya gotta chop, chop the middle one (pair) in your 3 (6) spring tank.
There are quite a few people (particularly on FleaBay) touting the 6 spring tank as an upgrade for your Fender.
Don't do it -- unless you're willing to mod the reverb circuit these tanks will have wayyy too much dwell. They work great in a reverb circuit with a dwell control though
PS: He can't turn it down because all his amp has is a mix control. The problem is the strength of the driving signal - fixed in most amps.
Thanks Todd..I took the middle one out and that helped me control it.a little better.I think I'm gonna order a 4 spring short delay from accutronic rather than the long delay....
