Brilliant guitar at this price. My one was only let down by the tuning machines, with some being very difficult or jumping that makes tuning possible but not easy. Suggest you budget for another set, but even with that cost added still a good value guitar that could cost you twice as much elsewhere or possibly even more. (You can also contact Thomann's good Customer Service who will always try to resolve.)
The Roswell pickups are good and should not regarded as a no name low quality as they are not. Certainly here in the UK they are available from some dealers as an aftermarket replacement. From what I can determine Roswell have been making pickups for other brands for a number of years and have only in recent years decided to market under their own brand. The only thing is whether the type of music you play fits well with these pickups. I think most who likes blues, classic or hard rock, etc or like me plays a bit of easy jazz as well will. However not being a shredder a thrash metal player cannot comment on that aspect. Having had to, over the decades, coil tap/split my guitars that is an additional benefit these days on many guitars including this one.
The fretboard was well finished, no fret sprout with good intonation out of the box. The fret ends were nicely finished.
Yes they could be more rounded and polished, thouhg that is more of a personal preference than requirement, but they don't catch your hands. The neck for me was great; not being too thick or too narrow. The neck was also straight and did not require any truss rod adjustment. Not a big job if required but nice when you don't have to, particularly if you were a new player and don't have the experience. The nut looks plastic as a lot of low to medium price guitars are these days though it does the job well. If you want you can always buy a bone, graphite, Tusq, etc and replace it. Or you could just buy a much more expensive guitar but that would appear to be an overkill just to get a preferred nut.
The bridge and stop tail piece are chrome plated cast, and do their job well. They are much better than some I have seen on less expensive guitars over the years.
Overall a good instrument and I will have no hesitation in buying one of the other Harley Benton guitars especially at the prices that they are offered at. However if you are looking for a high resale price then you are unlikely to ever get that with a HB guitar, but if looking for a good instrument that will last and be good got gigging then look no further. If you are into brand status along with a good resale price then look elsewhere and expect to pay a hell of a lot more.
