You might struggle with that, please correct me if I'm wrong, but a quick google has that RE-135 at ~£600 new. For that money, unless you find someone incredibly desperate for a random no-name guitar, on a bass forum, you're maybe looking at best at a second hand 4 string Rock Bass, you're probably not going to find a GPS model at that price in the year 2025, certainly not a 6er or something. Maybe if you're super lucky, you could find a Corvette STD 4 string, I've seen a few of those floating around in the £600-£800 price range on reverb in the past, but I doubt the people shifting those are gonna be interested in your guitar.
