Is it a 4" soundhole? If it isn't, it could limit your choices. I'm using a Baggs M1 active in my old L-00 (4"soundhole), but I also installed a simple switchable treble bleed tone control to take off the bright edge if necessary.
Why go with a sound hole pickup, when you can get a K&K PWM for $100? It’s easy to install. I put one in my 00 12-fret, and love it.
