Overall, a great value.
By Randy
I installed this in an Epiphone EB-3, so some routing & pickguard modification was required. The pole spacing is perfect, and the included spacer is necessary to get it a little closer to the strings: except in this case, the oversize design (of the spacer) won't work, as the pickup is up against the neck, so I will be making a custom one which is the same size as the pickup frame. The frame was attached to the pickup itself with only a ground wire, which made it a little difficult to work with until I realized, thanks to a certain bass forum, that the raised black surround was actually a silicone caulk that had separated from the pickup. I may repair that at some point, but it works fine now, and has a great clarity to it: I've read that the vintage versions respond well to dynamics, and this version seems to share that characteristic. It's not especially hot, but I'm sure the response will improve after I raise it up on the spacer. I'm very happy with my purchase, and the great looks are definitely a large part of its appeal.

great pu for narrow spacing basses
I use both the Novak Bi-Sonic and this one and they look nearly identical. Main difference is this Guild pu comes narrow spacing only. The Novak comes both narrow and Fender spacing but is over twice the price.

Classic is Back in Vougue
By Mark Groody
On a whim I put this pickup with a Bartolini 3 band in an Ibanez Artcore Long Scale with some Thomasik-Infeld flats.... Bang! Jack Casady's 68' Crown of Creation and Bless It's Pointed Little Head sound. These work well with the ACG filter pre's for the Lesh sound. I play all styles and use different basses, Alembic, Smith etc., but when called to recreate that old S.F. sound for tribute bands, everybody gets chills.

Sounds as great as it looks!

I build bass guitars and use these in one of my models. I own a Hammon Darkstar, so I was initially skeptical this pickup could even come close to the warm, full range, hot output of the Hammon. I installed these in my shortscale bass and had it strung up with both rounds and flats and I have to say I am very impressed with these reissues. They are a great value and I will continue to use them.

Most beautiful tone!

Bought a pair of these with the sole purpose of rewinding them. After much testing & reworking I came up with an acceptable combination that really rocks the house, yet can smooth out and nail that woody, mellow Starfire bass tone that the 60's Guild basses were famous for. I scatter wound with #41 straight enamel. 7.4k for the neck pickup, 12.35k for the bridge. I also switched to AlNiCo V magnets with a 3/4 charge. I potted these with a 50/50 mix of paraffin & beeswax.
