I bought this for an extension cab to use with my Milkman Amp. Couldn;t be happier with this speaker, has all the vintage Fender tones I was hoping for. The 40 watt rating was exactly what I needed. This speaker is destined to be THE replacement speaker for any vintage or reissue in need of accurate vintage tone!! The folks at AP treated me well, great price and quick shipping, much appreciated!!

The BEST choice ever. It transformed my 1970 Fender Deluxe Reverb amp into the BEST sounding single 12" speaker amp that I've owned. Nothing can even come close to the magic that George Allessandro has put into this speaker His description of this speaker is spot on. I've played Vox amps with Celestions and Fenders with Jensens, but NONE of them sound as GREAT as the GA-SC64. If you love your amp, but might not liking the sound of it anymore, change your speaker to this and you'll fall right back in love with it again. Don't buy a reissue when you have a vintage. Don't get it reconed when you can get BETTER/BEST.
