Chances are you already know Celestion's amazing cabinet speakers, and they've already meticulously created accurate and natural-sounding IRs of their most popular models. Impulse IR Loader comes pre-loaded with 12 of the finest, official Celestion digital IRs, hand picked from what TC Electronic believes to be the best IRs on the market. You can also download even more official Celestion IRs from their website.

For Impulse IR Loader’s slots 13 to 20 TC Electronic added 8 custom-made Pedal Platform IRs. This means that you become DI-ready and can play without bringing your amp and cabs.

TC Electronic created these IRs using both an amp and a cab, in order to give you that particular sound through a PA system or at home when recording direct through an audio interface. Whatever the case, make sure to place the Impulse IR Loader after your drive pedals in the signal chain to transform your pedalboard into a DI ready guitar rig.

A common woe for acoustic guitar players is trying to get a half-way decent tone when plugging guitars with piezo pickups into PA systems. To address this, Impulse IR Loader comes preloaded with Acoustic Guitar IRs in slots 21 to 25. Simply place it in front of your pedal chain, and load an acoustic IR to take your piezo pickup from dull to full.

The footswitch can operate in two different modes. Use A/B mode to toggle between two predefined IR’s. For example, you could have your favorite speaker IR for clean tone loaded as A and another for overdrive/distortion loaded as B for swift and effortless speaker swaps.

If you prefer to use Impulse IR Loader as a traditional effects pedal, you can set it to true bypass mode and simply punch it in or out when hitting the footswitch. True bypass switching ensures that it can take a permanent residence on your board without affecting your tone when not in use. To toggle the two modes on the fly during performance, simply press and hold the footswitch for a few seconds.

Impulse IR Loader is ready to take on IRs of up to 200 ms in length. In short, the longer the IR, the more details are flowing your way, giving you cab, amp, and acoustic IRs that resemble the real deal with unparalleled accuracy.

As a final touch, you can access a Global Compensation EQ with low-shelf and high-frequency filters for easy and natural integration with your various setups. It may sound like a small thing, but it's a minuscule detail with a monumental impact. Press both small-arrow buttons simultaneously and get instant access to quickly adjust the low-shelf and high-frequency filters with the single level knob.
