Celestion Impulse Response Mixes for John Petrucci’s Guitar Universe

We have provided three unique IR mixes that can be ported directly into your modelling hardware or DAW software, delivering breathtakingly realistic guitar speaker tone!

Creamback H Heavy Mix A

Starting with a closed back 1×12 IR for a full-on Creamback H tone, we blended in the rear mic from the open back 1×12 cab to round out the low end. Finally, to add girth and density we dropped in a Royer R-121 used on the closed 4×12 cab. The result is very dark and full; recommended for seriously heavy sounds.

Creamback Impossible 8-Mic Mix

Combining the weight of a Creamback M in a 4×12 cab, with the precision of a Creamback H in a closed back 1×12, the Impossible 8-Mic Mix simultaneously uses all three spot mics as well as the room mic for each cab! The result is another great hard rock tone that’s dark enough to command attention with a high gain amp setting, with a little added brightness and punch for lead lines that cut through.

“Gods of Thunder” Mix

First, all three spot mics (Royer R-121, Sennheiser MD421 and Shure SM57) were “simultaneously” located in the Dark 2 position of a G12-65 4×12 cab and mixed together to deliver a sound of both colossal weight and thrilling detail…. and then we took the mix to another level!

Next up a Royer 121 mic on a G12H-75 Creamback 4×12 cab, again in the Dark 2 location, adding supplementary low end and turning the G12-65 darkness into rolling thunder. An SM57 at the rear of a Creamback H 1×12 cab and a G12-65 4×12 room mic complete the mix by adding ambience, space and three dimensional complexity for a tone that’s big enough to fill the halls of Valhalla!
