I had a 55-01 and sold it awhile back. I miss that bass. I changed out the stock pre for a NTMB and it didn't change the tone at all, just added better pots. Someday I will buy another.
Huh, made a world of difference to mine. Got rid of the brassy edge & warmed it up... the aggressive growl of the stock soaps remains, which isnt necessarily a bad thing.
OH yea, BTW... I probably fit here just fine... but honestly, I am looking at making some sort of 5-StRing change.
