There are 3 different metric threads offered on toggle switches.
1. This unit is M3.5 x .6 (roughly 1/8") thread, fits most Epi LP and similar guitars 2. M4.0 x .7 (roughly 5/32") thread for many Japanese, Chinese, Taiwanese & other import guitars 3. M3.0 x .5 ( roughly 7/64") thread for many Chinese and other import guitars
It is very difficult to match all of these details up with specific models, we will help you anyway we can, but it is up to you to determine which know you need. If you do get the incorrect knob, please let us know, we do not have every color for every thread, but we do carry many of the combinations used in the market.
