before and after the blackface modification?
Obviously, many Silverface amp owners do make the modification,
but do all 100% like the mod? Any complaints?
Thanks for your responses. Toppscore.
Mine was a 1968. If the amp is in good working order there is no really good reason to mod it. The mods necessary to blackface are very easy and quick to do, but not really necessary. I believe it's the AA270 but YMMV. As for the sound, it sounds great stock. It's literally as close as you get to a blackface with a factory silver faceplate. The only really worthy BF mods to that amp are to the BIAS circuit, making it easier to tweak the bias to your liking.
