Forum member nicholaspaul had previously replaced the middle pickup in his Concord with a Samick brand but found it unsatisfactory.
He then offered us his recommendation for a GFS replacement:
“I just installed a GFS Alnico Boutique pickup in the middle position, replacing the Samick p/u.
It puts back the chime that the Samick obviously didn’t have and balances out the other two very nicely.
I know many people hate them, but I put in a phase switch too. I can now get some amazing piezo-type strumming tones out of it.
If anyone else is looking to replace their pickups, I can highly recommend GFS. Great prices, fantastic sound.”
