Well... Yes it's a Schaller Tremolo 2000 on the white strat.
Both of them are flat floating mounted with 3 aligned springs.
- The tuning stability is very good on both, the Schaller is little more "soft and flexible" or "smooth" when you use it.
- The build quality is perfect on both too. I notice the Schaller is quite heavy, with a big steel (or brass ?) block awesome good sustain...
- The sound... Mhhh difficult to say because they are mounted on two very different tone wood... but I feel the Wilkinson is little more warm sounding...The Schaller is clearer with better sound string separation.
I have Schaller locking and staggered tuner on the white strat and no tuning problem at all... The korina have Gotoh SG381 HAP staggered tuner, and I only have sometime the G string going out of tune when I heavily use the tremolo ; maybe because its not locking tuners...
Finally I slightly prefer the Schaller for the sound and feel, but it is not standard mounting with the pickguard (I cut it 5mm near the trem logo) So it's better on rear routing bodies :icon_thumright:
And sorry if I made writing mistake I'm French... Pffffiou I speak a lot ; I got have a beer now :icon_jokercolor:
