Cab and Mics

The cab used is a German 1*12 front-loaded and ported. While it may lack some low-end extension (below 100 HZ), it deliver a very punchy and authoritative sound. The speaker is a Celestion® G12T75, a very popular guitar speaker released in the 80’s. Marshall have been using them for years in their cabs. This speaker is really interesting, with a scooped medium range and a treble section that I personally enjoy more than the one of the Vintage 30 : I often use a 12T75 IR when practicing with high-gain sound with headphones.

Below a few samples based on a partial cover of War is coming, from Six Feet Under (https://www.youtube.com/watch?v=u5KXDAZNXus)

  • 2 guitar tracks panned hard left and right (Seymour Duncan SH4)
  • same IR left and right
  • No EQ post IR (HPF only)
  • The final track is lightly compressed with an opto compressor and very lightly equ’ed.
  • Overdrive and amp : TH3 Overloud with a Tube Nine overdrive and an England Burnsphere, lead channel

A few notes

  • With a bass heavy amp or sim, the low-end can become boomy and muddy : in this case, lower the bass on your amp / adjust your resonance / use a HPF and eventually cut the 120 HZ frequency by 1 to 3 DB.
  • The 6L6 power amp used for IR capture tend to scoop a little bit the 250-700/800 HZ area : if you raise it by 1 to 2 or 3 DB, you may get closer to the actual sound of this speaker.
  • the IRs are recorded with 2 different preamps and converters : the default preamp is a tube preamp, the -L suffix is a different setting on this tube preamp, and the “b” versions are recorded with a transistor based preamp (more clarity in the 7500-10000 HZ area).
