Zeus Pickups on Instagram: "Get yourself a knob puller! This thing makes your life so much easier! Makes removing knobs a breeze, plus you will never have to worry about damaging your finish when you remove a knob! I don't know if you can buy these. I found the model on thingiverse so we are not allowed to sell them. But we will give them away as a bonus with every pickup order. Ony more ideas for 3d printed guitar goodies? :)"
