Re: SA Standard Tremelo Vs. RG Fixed
The SA trems (both SAT30 and SAT-Pro) are good trems -- IMHO, they are on par with the Wilkinson VS-series (VS50 and VS100) which they are clearly modeled after. As with any non-locking trem, using some graphite or other lube (Big Bend Nut Sauce) on the nut and saddles makes a big difference. Locking tuners take it yet another step. Fettouhi, the SAT trems will NOT switch out with a Wilkinson due to non-standard stud spacing.
As I've mentioned in other threads, I think the SA series has been underestimated and overlooked, especially the Japanese made SA1260 and the SA420X (both discontinued). The 420 differs from all others in the SA line in having a piezo bridge and an Ultra neck. I also have an SA160 which I travel and perform with -- I absolutely love that guitar. But yes: the stock pickups on the SAs truly bite (except for the 1260 and 420, both of which had V-series pups).
Ibanez237 -- just out of curiosity... since you mentioned you like 22-fret necks, and you don't use the trem much, why did you rule out the SZ series?
