My 335 style arch top has suffered from loose pots for 15 years. Previously, I didn’t have the right tools to tighten them properly without risking scratches to the finish. No matter what I did, the pots would come loose again with the seasonal cycles of dry winters and humid summers.
This tool made the job so easy—I wish I had bought it earlier. The steel feels like proper tool-grade steel, and it's well worth the price over cheaper copies.
