Re: Recommended trems
There's nothing wrong with the Edge IIIs. That's just crap spewed, most of the time by morons who are just regurgitating what they've heard online, ususally by another moron. I have an Edge III, and have had ZERO problem with it, and I beat on it. I might have to check the tuning, once in a while, during a set, and usually it's still in, but other than that, it's solid (I do alot of reverse dives and regular dives, so, yeah, the trem and strings are getting put through the course).
I will say this: Some people are put of by the slip-in trem arm. I have NEVER lost the trem arm by it coming out of the socket. Once, the retainer got a little bit loose (I like an arm that stay where you put it). I merely tightened it, ever so slightly, and all was well, again. That could be chalked up to the unit settling in, though, as it was in the first 9 months of decent use. The unit IS lighter than, say, the Edge trem, which is my all-time favorite trem unit. However, I haven't had any problems with failed parts, stripped threads, cracked saddles or blocks, etc..
Now, for the other unit, you mentioned, the speedloader trems. If you are talking about the generic ones, like they sell on Evilbay, they are single-locking, and thus will not hold tune as well as a double-locking trem (in theory, at least), because, now there is a place for slack-storage of the strings. I say "In Theory", because I had Kahler trems on my Charvels and one of my strats, which are single-locking, and had no tuning problems with them, either, and they had behind-the-nut locking nuts, to boot. Additionally, I have not had the opportunity to try one of those "speedloader" trems out, but I'd be willing to bet they don't stay in, all that well. If I was on a budget, and wasn't playing regular gigs, maybe just bedroom playing, I might think about one on a guitar, till I could afford something else, but for a main guitar, on stage, I'll stay with my Edge III or something else.
I'd stay clear of the TRS IIs. I had an Ibanez that had one on it, for about a day, till I could take it back. Wouldn't stay in tune to save it's life! I hear the TRS is better, but like I said, that just what I hear.
Just my 2 cents....
