The ANVIL IR Pack by JST is a collection of strategically captured impulse responses brought to you by Joel Wanasek and Joey Sturgis Tones.

Not sure what an impulse response is? Click here.

With ANVIL, we’ve done the hard work for you by going through all the speaker and mic combinations, finding the ones that stand out, testing them in mixes, and then processing them so that you can quickly click, and get the perfect tone for your mix.


  • 125 fully mixed and processed IRs delivered as WAV files (5 Cleans, 5 Leads, 25 Rhythms, 90 Raw).
  • Can be loaded directly into any Toneforge plugin.
  • Phase matched mic positions per speaker cab for accurate blending of many mic/IR combinations.
  • Long length recorded and mixed IRs in 48khz/24 bit for incredibly authentic cab sounds.
  • Compatible with most modelers.

Whether you’re going for crushing rhythms, ripping leads, or modern clean tones, the ANVIL IR pack has the right Impulse Response to get your guitars sounding awesome.

These impulse responses are great for:

  • Creating tones from scratch
