Celestion G10 Greenback Impulse Response – The 10-inch Guitar Speaker That Thinks It’s a 12!

The latest guitar speaker to join our ever-expanding rank of IRs is the 10-inch speaker that thinks it’s a 12 – the Celestion G10 Greenback!

Celestion G10 Greenback Tone

Developed to recapture the legendary, familiar rock sound of Celestion’s 1970s 10-inch guitar speakers, the G10 Greenback’s ceramic magnet delivers the distinctive throaty growl and satisfying meaty low-end that’s reminiscent of its 12” counterpart.

You can expect a complex, enthralling mid-range and smooth, vintage top-end that remains sonically faithful to the classic sound of early ‘70s Celestion  10s, with the G10 Greenback adding real class to small cab combos. When combined in a 4×10 configuration, it gives rise to a raunchy, full-bodied tone, rich in low-end thump.

Five Decades of Rock & Blues

For the guitar players out there fond of historical accuracy, the term ‘Greenback’ is a generic term for several of our best-selling guitar speakers, including the G12H and G12M, that were originally released in the late ‘60s and ‘70s. What each of this Greenback family have in common is a ceramic magnet and classic green magnet cover. And collectively, while different models and cones provide their own unique tone, over the past five decades or more, the Celestion Greenback family has become a British icon of rock and blues.

The Celestion G10 Greenback resulted from a desire to replicate the tones from some of the 10-inch speakers built in the early 1970s. With focused lows, warm, ‘vintage’ treble and a bit more bass than you’d expect from a 10” guitar speaker, the resultant sound was more than a little reminiscent of the tone of a G12M: the infamous 12” Greenback.

The Celestion G10 Greenback speaker has now been meticulously captured by our expert sound engineers in a world-class room and captured as a speaker Impulse Response available for you to download today!

We recorded the G10 Greenback IR using three classic, pro-quality mics – the Sennheiser MD421, the Shure SM57 and the Royer R-121 ribbon mic. Each of these mics were placed in six unique positions around the speaker, titled with the IR files as Thin, Fat, Balanced, Bright, Dark and Dark 2. An additional rear mic position was also used for recording the open back cabinets.

These positions are all fully adjustable by the user when using the speaker impulse response files within your DAW, IR plugin or amp modeller. In addition to the three studio mics included with this IR pack, a Neumann TLM107 room mic was also used to offer the user to a huge range of tonal options.
