Cab and Mics

The cab used is a Mesa Boogie® Recto 2*12 loaded with its original Celestion® Vintage 30. This cab is viewed by many as one of the best cabs for metal sound. …. And it is not that easy to capture 😉

This collection is part of the 6L6 Serie II collections : it is using only a 6L6 power amp section together with a tube preamp. 19 IRs files are provided in this version.

A few notes

  • The proximity effect was fully used, without an aggressive low-cut : the positions 12 to 20 present a generous and present low-end (50-120 HZ). Adjust your HPF to your taste.
  • 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 DB, you may get closer to the actual sound of this speaker (ie under WOS 360 HZ + 1 or 2 DB, 800 HZ +1 or 2 DB)
  • the IRs are recorded with a tube preamp
  • cap edge and cone (p12 – 15 – 20) present the most balanced tone
