I've finally gotten around to assembling a project guitar from an old Pacifica neck and a PRS type body bought from fleabay... and have to say - that the GFS Mini 59's I bought for it are way better than I expected... certainly as good if not better than any mini HB's I've ever used...
The bridge model is especially good... just slightly overwound at 8.8k it has a tight, focused response with very balanced tone... thing I like about it is it's not 'too anything'... not too trebley, middy or bassy... just very responsive and the neck is a little warm for my liking but I have yet to shove a bit more foam under it to get it closer to the strings (they mount like P-90 types) before making a final decision on it... what's even more impressive is that I forgot to earth the bridge and there doesn't seem to be any ill effects from this... even in single coil mode... extraordinary!
I have also used a GFS AB-1 type bridge and stop tail and have to say that I am impressed with the quality of these as well... they feel a decent weight, are plated well and fit together very well with very little play... so... top marks to GFS for providing decent quality stuff for a very good price!!!
