I'm very honored to be the first guitarist who's able to check those new kind of bar bridges made by our member Dave-B. He sends me the uncommon ebano bridge and an aluminum version. Both are prototypes so the final bridges may look different. Ebano bridge in 9.5", aluminum bridge in 12" radius. Check those digits Dave's got the great idea to combine the advantages of a bar bridge with the perfect intonation of a TOM: based on the individual aspects from your guitar he's building a unique bridge especially made for you. Please read more details here: http://www.gretsch-talk.com/threads/nbd-bar-bridge-with-perfect-intonation.164274/ He builds a 9.5" radius ebano bridge for my Guild and a 12" radius aluminum bridge for my Hot Rod (based on their individual details). Both bridges are slotted for 10/46 strings. Part 1: The ebano bridge Ebano bridge Ebano is a man made material invented by Rocklite with similar or identical features like ebony. It is made from wood but it's pretty hard and tight. This bridge is black like charcoal and it's a featherweight about only 10 grams! It fits like a glove on the bridge base of my Guild and it sits close and fat on the thumbwheels, thanks to the plain and bigger bottom of the bridge. It doesn't rock noticeable (but I use bigger thumbwheels on the Guild). The bridge is awesome worked and perfectly slotted, it looks and feels like a piece of art. The radius matches the neck radius of the guitar 1:1. On the Guild Intonation is spot on. I've made a little mistake by sending the measurements because the floating bridge was a bit disaligned. Anyways: E: 100% A: 100% D: 95% G: 90% b: 100% e: 100%. The intonation speaks for itself. The bridge intonates as good as a well adjusted TOM! It's self-evident that a well intonating guitar sounds a lot better, no? Tone is paramount! I always thought a wooden bridge sounds pure jazzy and, hmm, somewhat "matte"- nope! The ebano bridge sounds transparent, open and very, very lively! It adds some warm midrange without cutting high frequencies and it allows the tone to clip in sweet overtones. The Guild is a great sounding guitar but with some icepick heights sometimes (there are some nasty high mids from the Franz pkups that always forced me to roll back the volume a bit): they're gone! There are no sitar tones, no buzz, no nothing but pure tone. I'm deeply in love with this tone. Playability is super comfortable, no sharp edges so palm muting is a pleasure. Tuning stability is perfect. No matter how hard I use the Guildsby, the guitar stays in tune like it should. I'm really impressed. I've played an aluminum Tru Arc, a stainless Compton and of course the stock TOM on my Guild- none of them came close to this bridge. The only aspect that makes me think is the more modern look of this really black piece on an oldskool guitar, but maybe I only have to get used to it. And I'll have to see if the ebano withstands string tension and Bigsby use. But I think so! The dBridges got an uncommon, innovative look, they are something else, really! No need to tell ya that this bridge stays on my guitar Stay tuned for Part 2 of my dBridges-review next time!
