If you visited the Seymour Duncan web page recently, you might have seen the above notice. The TB version of all humbuckers are currently unavailable. No, they are not discontinued. There is currently a supply issue for raw materials contributing to the parts production of this model. Do understand that this will translate into supply shortages at the distributors’ end. Simply put, you won’t see them at your local dealers’ for some time – at least some weeks (might go into months with winter & COVID compounding the situation).
