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.
