They are 2.1mm, which is the industry standard. I just tried a number of those jacks on the PSA-120 plug I have here at the warehouse, and they all seemed to fit just fine. They are a tight fit (on purpose), so you may just need to push a little harder than you think. It's also just possible you've received a defective jack. Maybe a bent pin, or something else could be causing the issue. In that case, take some detailed photos and reach out to customer service for a replacement: https://nextgenguitars.ca/pages/conta...
