Cab Pack 13: ML USA Bulb 4x12 UltraRes contains 227 User Cab IRs produced for Fractal Audio Systems by Mikko Logrén from ML Sound Lab in collaboration with Misha Mansoor from the band Periphery. You can find IR mixes made by Misha Mansoor in the ML Misha Mixes folder which also includes IR mixes from Cab Pack 7: USA Trad 4x12 UltraRes and Cab Pack 8: Brit TV 4x12 UltraRes.

This collection includes separate IRs of all four speakers of the cabinet to give you the full variety of its tones. This Pack also includes the Alloy IR Mix Collection, with intentional inter-microphone phasing to add the unique but pleasant character we expect when using multiple microphones on a real guitar cabinet.

Time aligning IRs is usually being done by using minimum phase transformation (MPT) which deletes all phase information from the IRs. This affects the sound, feel and dynamics of IRs. This Cab Pack includes raw IRs (RAW) for Cab‐Lab which retain all phase information and can be time aligned in Cab‐Lab 3.

User Cabs may be easily uploaded to your Axe-Fx II or AX8 using Fractal-Bot, Axe-Edit, or Cab-Lab. This pack also includes the high resolution .IR files required to create your own original multi-mic UltraRes™ mixes in Cab-Lab.

Please remember: It is illegal to share Cab Mixes containing these or any commercial IRs.


Cab Pack 13 features one speaker cab: the ML USA Bulb 4x12, based on a Mesa™ 4x12 Recto® Standard OS cabinet.

Microphones used include:

  • Shure™ SM57
  • Royer™ R121
  • Sennheiser™ e906
  • Sennheiser™ MD421

Each microphone was used on each speaker of the cabinet. They were positioned in a variety of locations, listening and measuring to find "sweet spots". Different speakers are marked with letters A (bottom left speaker), B (bottom right speaker), C (top right speaker) and D (top left speaker). The numbers mentioned after the letters describe different variations of the mic position. The Alloy folder includes mixed IRs with real life phase that we are used to hearing when using multiple microphones on a real guitar cabinet. The Ace folder includes our personal picks of the best material in this collection.

This Cab Pack was produced and engineered by Mikko Logrén of ML Sound Lab.
