MARSH G12M GREENBACK 8-OHM 4x12 - XR IR PACK

This XR IR pack is based on our Marshall™ 4x12 basketweave cab loaded with 8-ohm ’90s 6402 cone G12M Greenback speakers, rather than the 16-ohm Greenbacks Marshall normally puts in their 4x12 cabs.

The 6402 is the last of the truly great Greenback cones, and at 8 ohms rather than the traditional 16, it trades a little aggressiveness for smoothness in the upper mids. The 8-ohm version is what you find in a 2x12 AC30, not in a Marshall 4x12 — so we tracked down a clean set and built this cab around them. If you have ever wondered why a Mesa™ 4x12 sounds different from most other V30-loaded cabs, part of the answer is speaker impedance: Mesa uses 8-ohm V30s where most cab makers use 16-ohm, and a tube amp driving an 8-ohm load runs on a different output transformer tap, which changes the tone and takes some of the aggressive edge off in favor of a smoother cut. 

This pack puts that same 8-ohm behavior behind Greenbacks in a straight basketweave cab — a combination you won’t find in another Marshall 4x12!



This pack includes 9 different dynamic, condenser, tube, and ribbon microphones in 4 different positions across the speaker in single-mic and multi-mic blend configurations. 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.

 

 

This IR pack is a part of our new XR IR Collection [XR = extreme realism], which is 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 that we have ever created. When compared to the real mic’d cab using the same amp, it is difficult to discern any difference. We are proud to say these IRs deliver the truest representation of a cab in tone, feel, breakup quality, and harmonic information when pushed. Unlike our previous tone-matched IRs, these IRs are universal and can be used on any platform that can load IRs and are not dependent on using specific amp settings to sound correct. A Tone Factor Starters folder with 10 hand-selected IRs from the pack is included to help you get started quickly.
