Client wants me to add a Tone control similar to this (pic) to his archtop. where can I get one? Thx!

Let me start with this; I'm trying to find the root cause of difficult fret wire installation of two different SM fret wires. I've spent a lot of time gathering dimensions and experimenting with techniques wich could cause the problem. I enlisted the help of a colleague who arrived at a similar poor performance. His solution was to glue the fret ends/ beat the frets in. My "rather" is to find the root cause so I don't have to go thr…

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…

I am retopping a guitar and while it's open I want to reduce the mass of the back braces. Since the sides are in the way, I can't figure out how to cleanly cut the excess brace wood away; anything I've tried involves the handle hitting the sides and preventing a controlled, clean cut. Is there a tool - say a "pull finger plane" - that I can pull from the edge to the middle of each brace to facilitate this?

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…

Guitar neck topology is worth going microscopic. 🔬🦠 After building my starting surface from a wireframe network in the sketch environment; a system of 4-degree control point spline rails, tangent to projected isoparametric curves along the shaft — I can convert the NURBS surface to a T-Spline and start cleaning up the artifacts left behind by the original loft. In this demo I’m turning on Box Display, which feels strange at first because…

Hi everyone, I'm Martino from Hub of Acoustics, a collaborative project created by luthiers for luthiers. Our goal is to explore and teach acoustic principles that are directly relevant to instrument making. In 2026, we’ll be running four courses in different parts of the world, all focused on giving luthiers practical tools to better understand and control the acoustics of their instruments. We’re excited to introduce our very…

Back at tinkering with the new Isoparametric Curve tool in Fusion. Scroll down to PICTURES LETS GO! If you want to skip this little walk through Autodesk Fusion memory lane, clearing up some of the UI conFusion. Why something so seemingly basic, is just being added today. 2009- Autodesk Inventor, hybrid modelling experiment, parametric and direct CAD in one hybrid system. 2011- Autodesk acquires T Splines Inc. an organic modeller still in…

I had a feeling I should have updated Fusion before 3D Club... Todays New update introduced Project Isoparametric Curves "Isoparametric curves in the Sketch environment, adding new ways to extract surface U and V curves for more controlled lofts, rails, and surface transitions" ...The meridians on the shaft surface seen in the attached photo. I still haven't fully grasped how to align these between faces, attached is a quick…

Hello, I am building a bass VI for a customer. As with a Fender Bass VI he wants a control plate with 4 slide switches. 1 on/off switch for each of the 3 pickups, but with the 4the switch he wants to control the phase of the middle pickup. Any suggestions as how I should wire that? thanks!
