"Original 25-watt Celestion amp, this is a little bit more gritty, and we want a little more breakup out of that. If you don't see a microphone in front of it it's on but it's for the stage sound. This whole thing fills up this whole side of the stage. We don't obviously mic everything because we've got twelve different cabinets. You don't need twelve different microphones going everywhere. That's kind of silly! What we do is we pick and choose what really sounds good for certain things," says Joe Perry's guitar tech. (These are the speakers used inside the Marshall cabs.)more
these current production, made in china 25 watt greenbacks will do if you don't have any old G12M's around.... there are plenty of better clones on the market these days, but I got my pair of current production greenbacks for free, so I use 'em in my sealed 2x12 for the time being. They are a little louder and harsher than even the black backed G12M of the 70s and exhibit a nasal upper midrange compression when driven hard that even the 90s UK-made Ms didn't exhibit to this degree (and pulsonic coned M's don't have AT ALL, its a Kurt Mueller cone thing). But overall they are okay. I don't mind them and they have a different flavor than my usual blue/G12H pairing. Keeps life interesting and there are much worse british voiced speakers out there.
UPDATE: I had sold 2 of these and kept one paired with a vintage alnico speaker. I recently blew that one out with 15 to 20 watts of power. A UK greenback can take its full 25 and then some. It doesn't just have a voicecoil rub, it is BLOWN. Low farting/growling sounds only. So that's where the difference between UK and Chinese celestions is. Durability. I docked a star for the poor power handling.
