When it comes to cabinet emulation, impulse responses (IRs) provide digital snapshots of a real speaker, mic’d up in a real space. Having IRs at the appropriate point in your signal chain enables you to send realistic sound to front-of-house or for recording.

TC’s Impulse IR Loader – a tiny pedal the same size of the company’s mini-pedals such as the Ditto looper – aims to simplify and facilitate that function. The pedal offers 25 built-in IRs alongside 74 empty slots for loading your own IRs of up to 200ms in length. It also has EQ in the form of low-shelf and high-frequency filters.
