This was a #2 bridge that was lowered to #1 specs. It was originally designed to be externally mounted, but I used it internally (my guitar already had the hole in the top). You can use it either way. If you use it externally, the endpin jack attached to the tailpiece with Velcro (included). A new Dell Arte bigtone combo like this sells for $265. I am firm at $135 including shipping (domestic). Paypal preferred. This would be ideal for a Gitane or the like.
