Does anyone has opinions on this pickup?
The pickup, Dimarzio Fred.
well... ive got the dimarzio FRED as a middle pickup on my les paul, inbetween 2 Seymour Duncan Alnico 2's. it is traditionally used as a bridge pickup by Joe Satriani, who the pickup was created for. as a middle pickup it is very similar to the Seymour's i have, but with a fair bit more bite, and output. good sustain, which is why it is a good match with the Seymours. i'd get the pickup, its very much the nuts.
sounds a bit too much like satch, IMO- you can get a similar tone by using a normal bridge pickup with a half-cocked wah... if you ask me it's limiting the versatility of your pickup for no good reason. Of course, YMMV etc. and it's only my opinion.
I have a Mo'Joe (higher output Fred) and I highly recommend this pickup. Harmonics and sustain are insane. Go for it, you won't regret it.
