So...I've used a TruArc SerpenTune Aluminum bridge for wounded G for a year or so. I've been very happy with it, the intonation works great, there are no sharp edges for your palm, the smooth finish both looks and feels great. When I first ordered this bridge I ordered another one at the same time: a Titanium SerpenTune for plain G. My original fine idea was to have two Gretsches with different string sets, but since that I've had no opportunity to get me another guitar, for the obvious reason: no monney. But as our band business ceased not so long ago because of lack of a drummer, I got an idea that it would be time to try the Titanium bridge on my sole guitar. So I did, with stunning results... Compared to the Alu bridge, Titanium is really something different, as I've heard it to be described by somebody. The Aluminum does sound brighter and I liked that, but Titanium sounds so much richer, giving much more of those natural sounding middle range details, along with added harmonics. And warmth, without going overly warm. That's how I would describe it. The sustain is just incredible, too. The guitar rings longer now than it did with the Alu bridge. Even with the same old wounded G strings, that I used at the time of the bridge change. I wanted to compare just the bridge materials first, without changing new strings. Although Titanium is much heavier than Alu, it does not seem to kill the sustain the way my previous SS bridges have done. SS sounded colder at the same time. Of these last two facts I can't say if it's the SS vs Ti material, or make, which was different. I just love the outcome! Titanium does not sound as 'rockabilly' as Aluminum perhaps, but it gives you more possibilities to change your tone with the pup switches and amp controls. I've had a few two hour playing sessions on my own after that (oh, you poor neighbours) and am still very excited to play even more. Titanium is really something else! Here are some random pics, with the elementary cork sniffer content, too . But honestly, I just meant to give a few practical hints for other guitar geeks. When you put something like that under the bigsby arm when loosening the strings, you won't have problems with the loose arm or off jumping bigsby spring.
