Scaling a Guitar Amp Business with CNC: KSR Amps & ShopSabre
In this episode of Out & About with ShopSabre, we head to Ohio to visit KSR Amps. What started in a basement as a passion for fixing vacuum tube guitar amplifiers has evolved into a massive, full-scale manufacturing facility—and ShopSabre CNC machines are at the heart of their production.
The founder of KSR Amps breaks down his entire manufacturing journey, explaining why he specifically chose ShopSabre’s PC-based controllers for maximum file flexibility over embedded controls. We get an inside look at his shop floor, where his original ShopSabre 4896 runs dedicated aluminum chassis production, while his massive IS 510 handles the woodworking, easily fitting two 5×5 sheets of Baltic Birch simultaneously to cut dual speaker cabinets at once.
If you are on the fence about investing in a CNC router or wondering which upgrades are truly worth the money, this video breaks down exactly why you should never skimp on an Automatic Tool Changer (ATC), a vacuum table, or pop-up alignment pins.
