No price negotiations. No bulk purchase discounts (shipping discounts). Please refrain from individual negotiations. Please purchase directly without waiting for a response. I aim to ship within 24 hours, so I will not send comments until the item is shipped. Thank you for your understanding. *I do not issue receipts. Set of 4, unused. VOX-type aluminum machined number knobs. Size: Outer diameter max. approx. 25.0mm, height approx. 16.9mm. Shaft hole approx. 6.1mm, type that fixes the shaft with a 2mm hex wrench, so it can be used with both USA and Japanese pots. (Wrench not included, please prepare your own) Use for repairs and customization of vacuum tube amplifiers, tube amplifiers, stereos, antique radios, audio equipment, guitar amplifiers, and effectors, as well as for dressing up bizarre guitars. Images 5 and 6 are reference images for size comparison. *If you let me know in the comment section before purchasing, I can change to "Yu-Yu Mercari Mail Yu-Packet" (anonymous shipping) for an additional 50 yen.
