Legendary Tones - Celestion Heritage Series

legendarytones.com

The Celestion Heritage Series G12M and G12H Greenbacks are faithful reissues of the iconic speakers from the '60s, capturing the original's legendary midrange crunch and tonal characteristics. The G12M shines with its creamy compression and full-bodied tone, making it ideal for classic rock and blues. Meanwhile, the G12H boasts a louder, more neutral sound with stronger high-end response, suiting harder rock styles. Both models deliver on their promise to emulate the vintage sound, providing a fantastic alternative to scarce originals. Celestion's attention to detail ensures these speakers are a worthy investment for tone purists.

Don't re-invent the wheel.

Their presence on countless classic records have made them the golden standard of rock/metal guitar tone. It's nigh impossible to improve upon greenbacks. Mine are older late 80's UK made examples that have broken in magically over the years. My favorite speaker of all time.

Verified via Premier Guitar

Just like in our 2013 Rundown with the Hives, Carlstroem is still bringing the might with a one-two amp punch. He’s using a Divided by 13 JJN 50/100 that runs into an Orange PPC412 equipped with Celestion Vintage 30s (last time he was running Celestion Heritage Greenbacks in a different cab) and a Fender Vibro-King that pumps through three 25-watt alnico Jensen P10R-Fs. The amps’ controls and circuitry are shielded with foil because they and the Epiphone are sensitive to interference. (And an Orange Custom Shop 50 lurks in the background, as a backup for either amp.)
