Celestion G12M Greenback

The Celestion G12M Greenback has been the staple of classic rock tone for the past 30+ years now. It has been used successfully on recordings throughout the years ranging from Hendrix to Loudness. The Greenback comes in 12’’ format with a 25 watt power rating, 8 or 16 ohm configuration and a ceramic magnet.

The Greenback is the standard when it comes to that old school early speaker breakup tone. It has a lower wattage rating, and it’s a lot easier to push into speaker distortion than the higher wattage speakers. While some types of music don’t want this, that speaker distortion is part of its charm.

First of all, the speaker I’m reviewing is actually the Chinese one. There are about 5 or more Greenbacks on the market, and they all sound different. The Heritage, Classic, Pre-Rola, etc. all have different sounds going for them. There are different camps that argue as to which is better, but that’s not really part of this review. I’m just going to describe my personal feelings towards the standard Chinese version that you can find in the Marshall 1960TV cabs.

These speakers have a little bit of a bite to them, but they’re fairly pleasant in sound. They work awesome with Marshalls, but they can also work pretty well with a cranked 5150. One thing people worry about is the wattage, but in reality, these can handle closer to 30 watts per speaker, so there’s no real issue when running these with a higher wattage amp such as the 5150. Not only do they sound great, but they record fairly easily, too. If you ever get the chance to try out one of those Marshall cabs with the Greenbacks in them, I highly recommend trying them out. It’s probably my second favorite speaker out there.

I use a 2 X 12 cab for a Pop-Punk-Rock style very year 70-80 and we find ourselves grain of his own in this period especially in the part Punk rock well recess.

This is the British Its a pure state, a sound that quickly crunch has its low level but what makes its charm, slightly soiled with supports medium and low gloss but not too bulky which will deserve to be légèrememt raised by more bass EQ to come tickle sound very 70 if it sticks Fuzz there.

Personally I love, I have tried other HP JENSEN, CELESTON, EMINEMCE and you just know what we want, because for me, they each have their Reference and style of its own V30 for rock metalheads, the EVM12L for hard real big sound and JENSEN P12Q which seems more suitable for the Reference JENSEN C12K is ideal because in a way but in a 4X12 or 2X12 Solo.

Penssez 2 min amp already equipped with its HP technicians with skills, it stuck in the HP amps that made their success so it is not for nothing, so with regard to the greenback, we find in the Marshall Bluesbreaker, the Blackstar Artisan15 well recess AC30 and AC15 eternal which are still equipped.

End of argument ...

I mounted it in my HP Fender Deluxe Reverb for britaniser and warm up a bit. I use a transistor fuzz circuit and combining with Jensen C12K home provides a great thing with humbuckers but slamming into the very acute with single coil. I first replaced by a C12K Weber 12F150. Overdriven sounds are better defined but still sharp slap (the C12K and 12F150 are finally close enough). The Greenback is awesome! It softened the treble without tarnishing the grain. Mediums give a lot of "dog" and character and can move better in the mix with a color really british. The bass are not invasive (much better, we always put too!). Low power handling (25W) so the volume gaffe! I connected a power attenuator to protect it and it allows the output stage of the amplifier to work earlier. In short, great for HP and attractive grain genuine rock'n'roll!
