The Celestion G12K-100 – also known as the Celestion K100 – is regarded by many as our ‘Monster of Rock’. And if you’re familiar with our speaker range, you’ll know that’s up against some pretty stiff competition!
So, let’s delve into the tone of the G12K-100 and consider where this speaker response might be the perfect fit for your Celestion speaker IR or DSR collection.
The Monster Tones of the G12K-100
The Celestion G12K-100 was born in the ’80s, when rock and heavy metal guitarists were looking for ever more power and heft from their speakers. We were happy to oblige created by bringing together a G12T-75 with our heaviest ceramic magnet.
The result was a modern speaker which retained all the clarity and control of the T75, but with the addition of a tighter low end and a more relaxed treble. It adds up to a very powerful, full-bodied tone with a gritty, industrial feel in all the right places, especially on heavy, distorted playing, perfect for contemporary rock and metal genres. But the G12K-100 isn’t just about the heavy stuff – it delivers great tone right across the frequency spectrum and often finds use in small boutique combos bringing warm, melodic clean tones, with tons of midrange character, and plenty of articulation for fast, accurate country picking.
While the K100 may not be quite as widely known as other Celestion metal speakers such as the Vintage 30 or the T75, there are a number of prominent players who have at one time or another made the G12K-100 an integral part of their tone, either on its own or combined with V30s:
Kerry King – Slayer
Stephen Carpenter – Deftones
Graham Pinney – SikTh
Celestion G12K-100 Speaker IRs & DSRs
The Celestion G12K-100 speaker responses have been sampled in 5 different cabinet configurations: a 1×12 open back, 1×12 closed back, 2×12 open back, 2×12 closed back and 4×12 closed back.
The sound from each cabinet has been captured using three microphones widely used in the music industry – a Royer R-121, a Sennheiser MD421 and a Shure SM57. Each mic has been placed in six different locations – with an additional rear location for the open back cabinets. Each cab has also been sampled using a Neumann TLM 107 room mic, which can be used on its own or mixed with any other microphone to help create a fuller sound as required.
If you’re looking for traditional high gain sound, using the K100 4×12 cabinet will likely be your obvious choice if you just want to get great, heavy tone. Choose the Dark or Dark2 mic positions to maximise the low end or, if you’re using them in a mix with other guitars, you might want to try out the Thin or Bright options to help it cut through a little better.
You can mix the G12K-100 impulse response with any IRs in our range, of course, but here are a few suggestions if you’re wondering where to start:
Vintage 30 – In the analogue world, combining V30’s and K100’s in the same cabinet is a very popular option. The K100’s helps to thicken out the bottom end and add some grit, while the V30’s contribute their warmer vintage tone.
G12T-75 – Cut from the same cloth, the T75 and K100 are going to give you a subtly different tonal twist while keeping things tight and modern.
Greenback – Rated at 25W, it’s rare to find these in the same cabinet as the 100W G12K. But if you love Greenback tone and want something heavier, mixing in some K100 could be just what you need.
