A Player's Perspective on Recording Guitar and Bass
As a guitarist and bassist who has spent many (many!) hours in both home and professional studios, I understand the critical role an audio interface plays in capturing the tone you are looking for.
For guitarists, modern recording techniques often involve multiple tracks to create a full sound. The standard approach includes recording the same part at least twice, panning one take to the left and another to the right, which creates that massive stereo image you hear in professional recordings. Some sessions might even require four or more layers, combining different guitars, amps, or microphone positions to achieve the desired tone.
Therefore, having an interface that maintains consistent sound quality across multiple takes is crucial.
Since I’m primarily a bass player, I can say that recording brings its own set of challenges and requirements. A common professional technique involves recording at least two separate tracks: a clean DI (Direct Input) signal that captures the pure tone of the instrument, and an processed track with effects or amp simulation (or not). Moreover, during mixing, these tracks are often split into separate frequency bands – typically isolating the low end (below 200Hz) from the mid and high frequencies.
Consequently, your audio interface needs to handle these multiple signal paths while maintaining exceptional clarity in the low end.
What I’ve learned through experience is that the quality of your audio interface directly impacts several critical aspects of recording:
- The noise floor of your recordings (especially important for high-gain guitar tones)
- The accuracy of your bass frequencies
- The ability to reamp signals
- The overall “feel” of playing through the interface while monitoring
- The flexibility to experiment with different signal chains and routing options
Most importantly, your choice of an audio interface for guitar affects not just the recording quality, but also your workflow efficiency. These interfaces combine high-quality audio performance with guitar-centric and a dedicated app for full control of your gear.
In this guide, I’ll share my hands-on experience with IK Multimedia’s AXE I/O series, breaking down how each model handles these real-world recording scenarios and help you to choose the best audio interface for guitar.

Overview: During our recordings, the AXE I/O proved itself as the best audio interface for guitar. The Z-TONE circuit, just like the previous models, exceeds expectations – it genuinely transforms your guitar’s tone from sharp and precise to thick and bold with a simple twist of a knob. Think of it as having multiple pickup characters in one interface, amazing for bass.
The PURE preamp delivered crystal-clear recordings of acoustic guitars and bass, while the JFET mode adds a nice warmth tone that made electric guitars sing through high-gain amp simulations.
It offers direct monitoring and phantom power 48v, like the other 2 models of the series and the AXE I/O Control Panel allow you to to manage inputs and outputs, assign routing and controller inputs.
What was really cool was the dedicated Amp Out with ground loop protection – reamping has never been this noise-free and straightforward.

The Control Panel application: Your Command Center
Finding the perfect tone on your audio interface for guitar is easy with the AXE I/O Control Panel app, which significantly enhances your recording workflow.
The Control Panel features two main sections that give you precise control over your hardware. In the Interface tab, you can manage all your inputs and outputs, enable phantom power for condenser microphones, and adjust the ground lift to eliminate unwanted noise – particularly useful when recording high-gain guitar tones. You can also set your sample rate, configure direct monitoring for zero-latency recording, and adjust output volumes, all from a single screen.
For players who use expression pedals or footswitches, the Controller tab is particularly valuable. You can configure up to two external controllers, setting everything from MIDI channels and CC# to minimum and maximum values.
This means you could, for example, use an expression pedal to control your virtual wah effect in real-time, or use footswitches to change presets while recording. Moreover, on the AXE I/O model, you can customize the behavior of the Preset knob, making it easy to scroll through your amp simulations without touching your computer.
How to Choose the Best Audio Interface for Guitar
When selecting the best audio interface for guitar recording, consider these crucial factors:
- Input Quality Matters Therefore, look for interfaces with dedicated guitar inputs featuring high impedance (Hi-Z) circuits. The AXE series stands out with its Z-TONE impedance control, which can dramatically affect your tone.
- Preamp Character Most importantly, consider whether you want a transparent sound or some analog coloration. For instance, the JFET mode on these interfaces adds subtle warmth similar to vintage equipment.
- Resolution and Conversion Consequently, aim for at least 24-bit/192kHz capability to capture every nuance of your playing. Moreover, look for interfaces with high dynamic range for better handling of both quiet and loud passages.
- Connectivity Requirements Above all, assess how many inputs and outputs you need. Similarly, consider whether you’ll need MIDI connectivity for controlling virtual instruments or effects.
- Software Integration For example, included software like AmpliTube and TONEX can save you money while providing professional-quality amp simulations and effects.
- Real Amp Integration To clarify, a dedicated Amp Out with ground loop protection is essential if you plan to use real amplifiers or reamp your recordings.
Final Thoughts: Choosing the Best Audio Interface for Guitar
After this hands-on experience with the AXE I/O series, it’s easy to determine that each model serves distinct needs while maintaining professional sound quality.
The premium AXE I/O excels for professional studios and serious players, offering unmatched flexibility and control. Meanwhile, the I/O Solo provides an excellent balance of features and value, making it perfect for home studio owners who don’t need multiple inputs. The I/O ONE stands as an ideal entry point, especially for those starting their recording journey.
For comparison, interfaces like the Focusrite Scarlett 2i2 3rd Gen or M-Audio AIR 192|6 offer good general-purpose recording but lack the guitar-specific features found in the AXE series. The Universal Audio Volt 2 and MOTU M2 present strong alternatives in this price range, but they don’t offer the same level of guitar-focused features like Z-TONE impedance control or dedicated amp outputs.
