Gas 4x12 K100 is the Choptones Supercab IR Library created by capturing a Diezel* 4x12 with Celestion* G12-K100 speakers.

Gas 4x12 K100 is an extensive and systematic capture created with 12 microphones, 8 to 16 positions for each microphone and multiple Mic preamps, or a total of over 300 IRs. The cabinet has a straight front, closed back,  solid African Okoume construction, and is very powerful with a tight low-end. Its huge speaker has an enormous magnet and subsequently, a huge tone. The G12-K100 is great for modern high gain tones with massive bottoms, focused mid-ranges, and modern top-ends.

The captures were performed with a motorized mic stand in order to have consistent measurements across libraries.

The microphones used during the capturing session are:

• AKG* C414
• Audio Technica* 2035
• Audix* i5
• Beyerdynamic* M160
• Electrovoice* RE20
• Neumann* U87
• Royer* 121
• Sennheiser* MD21
• Sennheiser* MD421
• Sennheiser* MD441
• Shure* SM7
• Shure* SM57

Every microphone was moved to four different horizontal positions (Cap, Cap Edge, Cone and Cone Edge) and two distances, for a total of eight IRs each.

For some microphones, the set of eight measurements was repeated with the microphone off axis (45 deg).

All of the measurement sets were repeated twice with two different Mic preamps: a Neve* 1073 and a German preamp.

MADE FOR THE SUPERCABINET
This library was created for the TH-U Supercabinet that allows you to:

• Graphically browse the IRs in the library
• Blend multiple IRs and create totally custom and huge stereo guitar tones
• Compose new cabinet tones with the unique Multiband mode
• Export your crafted IRs in .wav format for use with all major hardware modelers and software IR loaders
