We’re continuing our best IR series with a deep dive into where to find the best bass impulse responses online in 2023. Similar to guitar cab impulse responses, bass impulse responses are digital captures of a bass cabinet, speaker, microphone, microphone placement, and the acoustic space in which it’s being recorded.

Impulse responses are captured and saved in .WAV format (or similar proprietary formats for specific hardware like Kemper or Axe FX) that can then be loaded in a DAW with an IR loader plugin or in a modeling bass impulse response pedal or amp. Bass IRs can be quickly changed, combined, or swapped out to completely change and dial in your tone. They are ideal for DIY musicians on a budget but are also widely used by popular recording artists and producers in professional music studios around the world.

If you’re brand new to impulse responses, check out the What Are Impulse Responses section in our best guitar impulse responses article for a more in-depth discussion on what IRs are and how they are made.

We’ve previously discussed DynIR and by Two Notes Audio Engineering in our best impulse responses for metal blog post. Before we dive in, it’s important to note that DynIR cabinets are only compatible with Two Notes Torpedo hardware and software.

DynIR technology isn’t built with the standard single IR files or collections but instead is a proprietary technology designed to accurately simulate amps and speakers. Two Notes proudly boasts that you’d need 160,000 studio-grade IR files to replicate a single DynIR Cab. Well, we’re not sure how they arrived at that number but we’re here to say that their DynIR Bass Cabinets are nothing short of impressive. With bass cabinet options based on popular cabs like Mesa Boogie, Ashdown, Markbass, and Hartke, you’d be hard-pressed not to find a tone perfect for your mix. DynIR Cabinets include multiple microphones based on studio-grade mics like Sennheiser, Shure, AKG, Yamaha, and Telefunken.

Bass IRs FAQs

What is the best bass impulse response?

The best bass impulse response is going to be entirely up to you and your tone preferences! However, if you’re looking for guaranteed quality paid bass impulse responses, then go with Celestion Plus or any of the other IR makers on our best-paid bass IRs list. There are also quality-free bass IR options by Panda Sound, Whisper Studios, and others!

How do you make a bass sound deeper?

Bass tones can be made to sound deeper using a variety of EQ settings along with using specific bass impulse responses. Low-passing your bass will cut out any of the higher frequencies that may add unwanted crispiness to your tone. Selecting a popular bass impulse response based on a cabinet known for a fuller tone can also make your bass sound fatter.

The actual bass instrument—including the wood, pickups, and strings—can also dictate whether you can get a deeper, fatter tone.

What do I need to use impulse responses?

Bass impulse responses can be loaded inside a DAW with an IR loader plugin. You can combine them with a bass amp plugin like Amplitube to recreate a full digital bass rig inside your DAW.

Bass IRs can also be used in modeling pedals like the Boss GT-1000 or in modeling amps like the Kemper.
