Re: Check this axe/ID the bridge
The bridge is a licensed floyd, definitely not an ibanez design. Unfortunately it looks to be of rather poor quality too, seeing as the metal the screws are made of is pretty raw, and both knife edges are flat (Something most trems avoid doing, since it allows the bridge to shift left and right.)
Looking up Bradley guitars seems to point to them being a poor to middling copy guitar maker, but it only mentions them copying gibson designs, not anything like that guitar, so this may be an own brand model.
Regardless, if it plays nicely, I have no reason to believe its not a perfectly servicable 7 string, though I would look into getting that bridge replaced with a higher quality model asap.
