Re: is this a good trem?
There are two variants of the TRS trem: the original TRS, which is made in Japan; and the TRS-II, which is made in Korea. The original TRS is of significantly better construction than the TRS-II. It has a harder baseplate, although the studs are still kind of soft. I have the TRS-7 (Takeuchi, MIJ) on my RG7420, and while it's not great, it stays in tune and gets the job done. It does feel significantly stiffer than an Edge trem. Perhaps others can chime in with their experience, but make sure you differentiate between the Japanese-made original TRS, and the Korean-made TRS-II.
