No job is too small or too big for Guitar String Manufacturing (GSM). Generally, other string companies' private label quantity requirements are large requiring you to invest a ton of money into the packaging. That can use up a lot of your capital just to get your company off the ground.
Our low minimum order quantity limits, along with quick turnaround, enable you to operate with low inventory and minimal financial investment. Once your brand starts to take off, we will grow with you! There is no need to throw tens of thousands of dollars into your new string business. Start comfortably, and we will grow together.
More importantly, the differentiator between string companies is the type of material they use, the way the strings are constructed, and the machines used to produce a final product. Not all strings are the same for this reason. Each manufacturer has its recipe when manufacturing a string. There is the core-to-wrap configuration, a maintained pitch angle in which the wrap is applied, the speed at which the wrap spins, and the machinists' long-term expertise in manufacturing musical strings.
Core-to-wrap coupling (the way the wrap is applied to the core ) is a huge factor. You cannot just spin wrap wire on a core and hope it sounds good. The way the wrap is applied to the core is critical to the strings sustain, projection, and tone longevity. Our one-off custom ball end machines ensure the right twist-loc around the ball is applied. Without this, a string can either come off at the ball or slip which causes tuning problems. Each string is inspected three times, then hand coiled and placed into its envelope.
GSM has had long-term relationships with raw materials suppliers that span over 40 years. Although technology has changed, USA alloy materials have become better and more reliable. Every string that comes off the production line is made by a machinist one by one. That machinist controls and maintains the consistency from string to string.
