Hi guys, it's my first post here. First of all, english is not my first language, so I'm sorry for any mistake or its a bit rough. Recently I have a Sterling Maj200xsm from a costumer that has tunning issues with the tremolo. Any of you has experience with this model? I made a full set up and I checked the nut, saddles, springs, and dont found the trouble. Sometimes there are no issues at all, then the 2º and 3º string goes higher, then…

I am a retired dentist. One saying we had was, “You can’t fix what you can’t see.” And another was, “The day you start working with magnification will be the best and worst day of your practice.” The worst because you will see what you have been missing, and the best because you will never miss it again. So even though I have my Dan E. Model visor loupes, and my retired dental loupes on throughout the day, sometimes, it’s not enough. I pi…

Dialled in the Beta, much further. Now at v1.1.0 Echoing Christopher Alexander’s argument in the first half of “Notes on the Synthesis of Form” here. Parametric, Semi-Lattice Structures. Centres within Centres, interacting to form the whole. A living structure. Because of the dimension of time, and feature hierarchy, and methodology we end up with a Centre Oriented Semi-lattice Hyper-graph, or COSH for short. This will be available on the…

Greetings fellow Looths! I recently received a request from a customer to replicate Kurt Cobains 59 Martin, starting with a Sigma DM3. I have pasted the customers email to me below. While I have been a looth hobbyist for many years, I just recently opened my official business, Finger Lakes Guitar Works, and am just getting off the ground and a good flow of repair work is already coming in. While I feel 100% confident in my abilities to…

I did a pretty big update to my web tools last week. These are updated from the older versions I had up on celestialinstruments.com. There’s an updated FFT tool now, plus mode detection for guitars and plates, wolf note detection, played-note energy transfer, monopole mobility, plate thickness calculation, and 1/2/3/4 DOF modeling that can be prefilled from FFT data. The part I’m most excited about is being able to fit a measured guitar re…

Technically this is a repair, but I thought there would be some crossover with building, so I posted here as well. A 1950s Gretsch Town & Country Rancher 6021 is missing the two braces on either side of the sound hole (see photo). Because this is such a wide instrument (17” lower bout), I’m thinking that installing those missing braces will help with the stability of the top in addition to repairing the cracked/loose ladder braces. The…

I was finally able to model something like a Gibson L7 top plate! Now I'm trying to build my f-holes... My only reference is the Benedetto archtop book, where it puts a few rules of thumb about how the f-holes should be placed. My question is, how precise are we talking here? One of the rules of thumb is that the bridge intersects at the midway point of the f-holes. Does this imply that the f-holes are at a certain location on the plate,…
