SAMPLE XR IRs â A few sample IRs from our '76 Marshall G12M Blackback 4x12A XR IR Pack, so you can hear how different the cab sounds across mic types, positions, blends, and processing options. đ
Download the complete XR IR Pack below on ToneFactor.co, featuring dynamic, condenser, and ribbon mic IRs in multiple positions, along with expertly crafted mic blends and optional outboard gear processing for maximum tonal versatility. âĄď¸
This XR IR pack is based on our vintage 1976 Marshall⢠angled 4x12 cab loaded with Celestion⢠G12M Blackback speakers, featuring their original â1777â Kurt Mueller 75 Hz cones.
This cab has a bright, in-your-face voice, with an immediate pick attack and a clear upper-mid range. Power chords stay tight and defined, and leads jump right out of the mix. An excellent speaker and cab for anything from classic rock to modern high-gain tones.
This IR pack is part of our XR IR Collection [XR = extreme realism], the result of countless hours of IR experimentation, development, and A/B testing. The XR Collection is our latest and most accurate line of impulse responses we have ever created. When compared to the real mic'd cab using the same amp, it is difficult to discern any difference. These IRs deliver the truest representation of a cab in tone, feel, breakup quality, and harmonic information when pushed. They are universal, can be used on any platform that loads IRs, and are not dependent on specific amp settings to sound correct.
MIC POSITIONS
Each mic was captured in 4 positions across the speaker: 1 = Center Cap (brightest), 2 = Inner Cone, 3 = Mid Cone, 4 = Outer Cone (most low-end). Positions 2 and 3 tend to be the most balanced. Start with a position 3 IR for a balanced tone, then try 2 for brighter or 4 for warmer.
Each single-mic IR includes 3 variations: Unaltered Mic, Enhanced, and Top Boost, giving you raw and studio-refined tonal options for the ultimate IR experience.
