It is essentially a copy of the well-known BSS AR133. I can't know what differences it has in sound since I don't have the BSS to compare, but from reviews I read on Thomman (although I bought it from Richard), it is very close. However, for half the price, it is decent, it is a quality construction and personally, I use it for electric-classical guitar and I am very satisfied. I didn't give it five stars because obviously there are much better and more expensive D.I.s, but for someone who doesn't have or doesn't want to spend a lot, it is a very good choice.
