Recording guitar requires an audio interface with a high-impedance instrument input that captures natural pickup tone without impedance loading. Most entry-level interfaces have microphone preamps (low impedance) — the best guitar interfaces prioritize instrument input design.

This guide covers interfaces optimized for guitar recording, from budget-friendly to professional-grade. All prices reflect mid-2026 used values.

The 7 Best Audio Interface for Guitar

#1

Focusrite Scarlett 2i2 4th Gen

USB audio interface · 2 mic preamps, 2 line/instrument inputs, 24-bit/192kHz, USB-C, impedance-bridging instrument input, Auto-Gain$120–$170 used

Best for: Best all-around guitar interface, most versatile, best value

The Focusrite Scarlett 2i2 is the most popular guitar recording interface for home studios. The instrument input is impedance-bridging (high impedance) which provides natural guitar tone without a DI box. The Scarlett preamps are transparent and clean for guitar recordings. 4th Gen adds Auto-Gain (automatic level detection). Used at $120–170, the 2i2 is the best value for guitar recording starting point.

What to check used: While the instrument input is high impedance, the Scarlett's impedance is not as high as dedicated guitar-optimized interfaces (IK Multimedia AXE I/O). For maximum natural tone, add a passive DI box (costs $50–80) to the guitar input.

#2

Universal Audio Volt 276

USB interface with vintage mode · 2 mic preamps, 2 instrument inputs, Unison analog modeling for vintage guitar tone, 24-bit/192kHz, USB$200–$280 used

Best for: 76 vintage preamp modeling for guitar color and warmth

Universal Audio Volt 276 features Unison analog modeling that applies a Neve 1073 vintage preamp sound to incoming guitar signals. This is more sophisticated than simple EQ — the modeling emulates the harmonic saturation and color of classic analog preamps. For guitarists seeking warmer, vintage-sounding recordings, the Volt 276 adds pro-level preamp emulation. Used at $200–280.

What to check used: Universal Audio requires LUNA OS (macOS-specific) or UAD plugins (subscription-based) to use Unison modeling on Windows. Without subscription, the Volt 276 is a standard interface.

#3

Audient iD4 MkII

USB interface with JFET DI · 1 mic preamp, 1 JFET DI input (guitar), 24-bit/192kHz, USB-C, class-leading preamp transparency$100–$150 used

Best for: Most natural guitar DI tone from JFET solid-state amplification

Audient iD4 MkII features a JFET (solid-state transistor) DI input designed specifically for guitar. The JFET circuitry provides the most transparent, natural guitar tone of any entry-level interface. The iD4's preamps are industry-leading for transparency — every nuance of the guitar signal is captured. Used at $100–150, it is one of the best values for guitar tone.

What to check used: The iD4 MkII has only one microphone input and one guitar input — not suitable for recording two simultaneous inputs (e.g., vocal + guitar). For tracking full band, upgrade to the iD14 or iD44.

#4

MOTU M2

USB interface with class-leading noise floor · 2 mic preamps, 2 high-impedance instrument inputs, 24-bit/192kHz, USB, -128dBu noise floor$120–$160 used

Best for: Exceptional dynamic range and quiet preamps for clean guitar recording

MOTU M2 has an industry-leading noise floor (-128dBu) that approaches professional studio interfaces. The low noise is particularly valuable for quiet guitar recordings (fingerpicking, jazz). The high-impedance instrument inputs preserve natural guitar tone. For guitarists concerned with noise and dynamic range, the M2 is exceptional value. Used at $120–160.

What to check used: MOTU interfaces require more driver setup than Focusrite. Mac support is excellent; Windows driver support is adequate. Test on your system before committing.

#5

IK Multimedia AXE I/O Solo

Guitar-optimized USB interface · Proprietary high-impedance guitar input (mega-ohm impedance), mic preamp, amp matching, 24-bit/192kHz$120–$170 used

Best for: Highest-impedance guitar input for natural, uncolored tone

IK Multimedia AXE I/O Solo is designed exclusively for guitarists. The input impedance is tuned to match high-impedance pickups — guitar signal is captured with maximum natural tone. AXE I/O Solo includes amp matching (models classic guitar amps) and tons of amp/cab simulations. For electric guitar recording in a DAW, this is a purpose-built interface. Used at $120–170.

What to check used: AXE I/O requires iCloud login and sustains an ongoing subscription model for amp packs. The base amp models are included free, but accessing additional amps requires IK Multimedia Marketplace subscription.

#6

Apogee ONE for Mac

Compact USB interface · 2 microphone inputs, high-impedance instrument input, 24-bit/96kHz, USB-C, compact form factor$100–$150 used

Best for: Professional interface for Mac users, known for transparent guitar tone

Apogee interfaces are professional-grade with transparent preamps. The Apogee ONE for Mac (Mac only, not Windows) has legendary guitar tone. The instrument input is high-impedance and yields pure guitar signal capture. Apogee preamps are known for clarity and low noise. Used at $100–150, this is a professional choice for Mac users.

What to check used: Mac-only interface — not compatible with Windows. Also discontinued, so only used units available.

#7

PreSonus Studio 68c

USB-C interface with 6 inputs · 2 mic preamps, 4 line/instrument inputs, 24-bit/192kHz, USB-C, 4-band mixer, compact$180–$260 used

Best for: Multiple guitars or recording full band with guitar

PreSonus Studio 68c is a compact interface with 6 total inputs — room for 2 microphones + 4 instruments (perfect for guitars + bass + synth). The preamps are clean and transparent. For tracking full band with multiple guitars, the 68c is excellent value. Used at $180–260.

What to check used: The Studio 68c is more complex than the 2i2 — the mixer mode can be confusing for beginners. For solo guitar recording, stick with 2-input interfaces; for full band, the 68c is optimal.

Frequently Asked Questions

What is impedance and why does it matter for guitar recording?

Impedance is the resistance to electrical current flow. Guitar pickups are high-impedance sources (around 100k–500k ohms). Low-impedance interfaces (like microphone preamps) can load down guitar pickups, causing tone loss and frequency response changes. High-impedance inputs preserve natural guitar tone. Most audio interfaces have mic preamps (low impedance) — the Focusrite Scarlett's instrument input is impedance-bridging (suitable but not ideal). Guitar-specific interfaces (AXE I/O) have mega-ohm impedance inputs designed for guitars.

Should I use a DI box or plug my guitar directly into the interface?

For home recording, direct to interface is fine if the interface has a high-impedance instrument input. For studio-quality tone, a passive DI box ($50–80) between guitar and interface interface provides impedance bridging and ensures natural tone. For budget setups, plug directly into the instrument input. For professional results, add a DI box.

Can I record my guitar amp instead of a direct guitar signal?

Yes — mic your guitar amplifier with a condenser or dynamic microphone (Shure SM57 is standard) and connect the microphone to an audio interface. This captures the amp's natural tone (cabinets, distortion, character). Direct recording captures the pickup signal, which you then process through amp simulations in your DAW. Both methods are valid: amp mic = natural amp tone; direct = flexibility for post-production amp choices.

What is the difference between a 1-in/1-out and 2-in/2-out audio interface for guitar?

A 1-in/1-out (Audient iD4) has one microphone/instrument input and one line output. A 2-in/2-out (Focusrite Scarlett 2i2) has two inputs and two outputs. For solo guitar recording, 1-in/1-out is sufficient. For vocal + guitar, bass + guitar, or recording two guitars, 2-in/2-out is necessary. For most home guitarists, 2-in/2-out is recommended.

Do I need an audio interface for recording guitar in my DAW?

Yes — to record audio from a guitar into a computer, you need an audio interface. The interface converts analog guitar signal to digital audio that your DAW can record. You could alternatively use a USB microphone to mic the amp, but direct recording via an interface is the standard approach.
