I think most people on here will have tried one of their models. I've tried a few myself including LP, strat, and tele copies. All of which were fantastic guitars for the money, with a fit and finish to rival far more expensive competitors. Obviously all the hardware is of a very high quality and is all deisnged by Trev Wilkinson (as are the guitars themselves i believe).
I have not tried the Advance series but i would happily hazard a guess that they would be of an even higher quality than the standard models.
