imo the smaller Hagstrom in post #1 sounds just like a regular Bisonic, at least in Guild basses. Someone here, possibly N. Miller (? forgive me please if that is not right), i belive reported they played a Hagstrom bass with that pickup, and said it didn't really sound like a Bisonic...assuming we were talking about the same pickup...but someone had posted a video a while back of a Starfire bass with one of those, and it sounded like a Bisonic to me.
Also the bass in post #1 has been for sale for many many years on CL. guess the guy really is not budging much on the price, but he appears to have done some HW this time, and has come down a little on asking, so seems more motivated.
Have to report also, previously when this was listed, there was very faint numbers visible on the back, like someone wrote something like a phone number on a piece of paper, with a magic marker, and was using the back of the bass as a desk, and it bled thru, or something like that. Previously, the seller was quite upfront about the numbers on the back with photos, etc. so, he may have had it buffed out since it looks pretty good in the photo now, and there is no mention of it. it may have been no big deal and an easy fix, the numbers were super faint. it could have been an ancient school inventory number or something. anyway it wouldnt stop me or affect value much for me, and appears to have been addressed. just in case anyone is serious on this, thought i'd mention that in the event there is a cosmetic blem or repair on the back of any kind, it wouldnt be such a surprise.
