Cab and Mics

The cab used is a Zilla® Fatboy (2*12) loaded with a Celestion® G12K100 and a Celestion® Vintage 30. This collection contains the Vintage 30 IRs. The Zilla® Fatboy is a very good and balanced 2*12 custom cab, made to order by Zilla Cabs : check ZillaCabs website at https://www.zillacabs.com.

This collection is named version “III” as it is the 3rd setup iteration that I use for this cab : it is using only a 6L6 power amp section together with a tube preamp and a different A/D converter than the collection previously released. 39 IRs files are provided. This version is different and sounds better than the previous one, with a more balanced tone and a stronger low-end section. See the usage notes at the end of this page.

A few notes

  • The proximity effect was fully used, without an aggressive low-cut : most of these IRs present a generous and present low-end (50-120 HZ) but less important than for the G12K100 speakers. 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 (P10 -12 – 15 – 20) present the most balanced tone
