Celestion G12T-75 Speaker IRs & DSRs – High Gain Clarity and Control

Also referred to by many as the Celestion T75, the G12T-75 offers a combination of assertiveness and great clarity that will appeal to those looking for robust modern tone, as well as decades of heritage to its name.

The Celestion G12T-75 is available as both IRs and DSRs, the latter of which is for us exclusively with our ground-breaking SpeakerMix Pro plugin.

Let’s dive into the tone of the G12T-75 and what you can expect from this range of speaker responses.

Celestion G12T-75 – Origins and Tone

The Celestion G12T-75 was originally conceived in the ’80s, as a more powerful ‘hot rodded’ version of the G12M Greenback, ideally suited to the high gain amps that were becoming more common around that time.

It’s hard to say whether the G12T-75 helped to influence the development of a more modern, industrial sound that characterised 80’s metal, or whether it was the other way around; but either way, it has become firmly established in the Celestion firmament, proving itself to be far more than just a speaker of its time.

Its punchy low end, aggressive mids and balanced highs have been incorporated by successive generations of metal artists from the 80’s through to today..

As you might expect, the G12T-75 is much favoured among professional guitarists looking for a full-on, heavy, but modern, tone for metal or rock. Here are just a few Celestion Partners in Tone who specifically look to the G12T-75 to achieve their distinctive sounds:

  • Yngwie Malmsteen – “I like the Celestion G12T-75 speaker because it is very fluid and complements the violin-like tone and feel of my guitar playing.”
  • Joe Satriani
  • Dave Murray, Adrian Smith and Janick Gers of Iron Maiden
  • Jon Donais of Shadows Fall (used with Vintage 30s)– “Celestion make the best hard rock heavy metal speakers on the planet. I wouldn’t put anything else in my cabinets.”

Celestion G12T-75 Speaker IRs & DSRs

The tone of the G12T-75 is now available for you to download as impulse responses or dynamic speaker responses, in five different cabinet options (1×12 closed and open back, 2×12 closed and open back, and 4×12 closed back) with three microphone options (Shure SM57, Royer R-121, Sennheiser MD421, and Neumann TLM 107 room mics).

Used primarily for heavy rock and modern metal, T75s are often combined within a 4×12 cabinet with other speakers, most often Vintage 30s or Greenbacks.

By adding the G12T-75 to your speaker response collection you can achieve a similar effect by mixing different speaker IRs to get the balance you want between warm vintage tone and something more primal.

Above all, the G12T-75 IRs and DSRs will appeal to anyone who enjoys mixing up their tone with a touch of the unconventional or rebellious. Enjoy on its own for some hardcore, high-volume grunge– or use it to complement the tone of one of your other favourite speakers for an unexpected tonal twist.
