The best audio interface for guitar gives you a clean high-impedance input, low latency so you can play in time with amp sims, and reliable drivers. You don’t need to spend a lot — modern budget interfaces sound great — but a few features matter more for guitarists than for anyone else. This guide covers the strongest options and exactly what to look for.

What a guitarist needs from an audio interface
A proper Hi-Z (instrument) input
An electric guitar or bass needs a high-impedance (Hi-Z) input, usually a front-panel jack labelled “instrument” or “inst.” Plugging straight into a line input instead loads the pickups wrong and dulls your tone. Every interface here has one, but always check the input is switched to instrument mode.
Low latency
Latency is the delay between playing and hearing the sound back through an amp sim. Too much and the rig feels rubbery. Good drivers and a small buffer size keep it tight — our guide on audio latency explains how to set this up. Some interfaces also offer near-zero-latency monitoring.
Inputs and outputs
One instrument input is enough for solo guitar. Get a two-input interface if you want to record guitar and vocals together, or mic an amp and capture a DI at the same time. That dual capture lets you reamp later.
Reamping capability
If you plan to reamp through real pedals or amps, you’ll want a balanced line output to feed a reamp box. Most interfaces have spare outputs that work for this.
The best audio interfaces for guitar
Focusrite Scarlett (Solo / 2i2)
The Scarlett line is the default recommendation for good reason: clean preamps, a dedicated instrument input, dependable drivers, and a price that suits any home setup. The 2i2 adds a second input for tracking two sources at once.
Universal Audio Volt series
The Volt interfaces are well built and include a switchable vintage preamp mode that adds gentle warmth — flattering on guitar going into amp sims. They’re a strong pick if you want a bit of analog character before the signal hits your DAW.
Audient iD4 / iD14
Audient interfaces are known for excellent converters and a great instrument input (their “JFET” D.I. is well regarded). If sound quality per dollar is your priority, the iD series punches above its size.
IK Multimedia AXE I/O
The AXE I/O is built specifically for guitarists, with selectable input impedance to shape how your pickups respond, a dedicated reamp output, and a tuner. If guitar is your main focus, it’s the most guitar-centric option here.
Universal Audio Apollo Twin
The Apollo Twin runs UAD plugins on its own hardware, including amp and pedal emulations, so you can monitor through high-quality tones with very low latency. It’s a premium choice that doubles as a serious production interface.
How many inputs do you really need?
Be honest about your workflow. If you only ever record one guitar at a time, a single-input interface like the Scarlett Solo is plenty and saves money. Step up to two inputs if you record with a singer, want to mic a cab while also capturing the DI, or might record bass and guitar together. For most home guitarists, two inputs is the sweet spot.
Setting it up for guitar
Once you’ve chosen an interface, plug into the instrument input, set your levels with healthy headroom (see gain staging), choose a small buffer size, and load your amp sim. Our walkthroughs on setting up an audio interface and building a home guitar recording rig take it from there.
Connection type: USB, Thunderbolt, and bus power
For the vast majority of guitarists, a USB interface is all you need — it’s affordable, plug-and-play, and plenty fast for tracking guitar with low latency. Thunderbolt interfaces (like the Apollo Twin) offer even tighter latency and higher channel counts, which matters more for big multitrack sessions than for solo guitar. Most small interfaces are bus-powered, meaning the USB cable supplies their power, so there’s no extra adapter to carry — handy for a tidy desk or recording on a laptop.
Onboard DSP and amp modeling
Some interfaces do more than convert signal. The Universal Audio Apollo line runs UAD plugins, including amp and pedal emulations, directly on the interface so you can monitor through pro-quality tones with almost no latency. The IK Multimedia AXE I/O pairs naturally with Amplitube. These features are a nice bonus, but don’t overpay for them if you already own amp sim plugins you love — a plain, clean interface plus your favourite amp sim covers the same ground.
Preamp quality and headroom
While you’ll often record guitar through the instrument input rather than a mic preamp, preamp quality still matters the moment you mic an amp or record vocals. Clean preamps with plenty of gain and headroom keep your captures quiet and uncoloured. The interfaces here all have capable preamps; the UA Volt and Audient iD series are especially well regarded for the character and clarity of their front ends. Whatever you choose, set levels with healthy headroom rather than chasing maximum loudness.
Future-proofing your choice
Buy slightly more interface than you need today and you’ll grow into it. A two-input interface costs little more than a single and unlocks miking a cab plus DI, or recording a duo. If you can see yourself adding outboard gear, reamping, or recording drums down the line, a four-in/four-out unit gives you room. But don’t over-buy: a giant interface gathering dust is wasted money when a Scarlett 2i2 would have done everything a bedroom guitarist needs.
Also weigh software and driver support. Established brands like Focusrite, Universal Audio, and Audient maintain their drivers for years and across operating-system updates, which keeps your rig stable. Many interfaces also bundle plugins — sometimes including amp sims or effects — that can be a genuine head start for a new home studio. Reliable drivers and a healthy bundle add real value beyond the raw specs on the box.
Frequently asked questions
Can I plug my guitar straight into any audio interface?
Only into a high-impedance instrument input, which most interfaces have on the front panel. Make sure it’s switched to “instrument” or “Hi-Z” mode. Plugging a guitar into a line or mic input gives a thin, weak tone.
Do I need a special interface for amp sims?
No — any decent interface with low latency and an instrument input works with amp sims. Lower latency makes playing feel tighter, so look for good drivers and the ability to run a small buffer size.
One input or two for recording guitar?
One is fine if you only record a single guitar at a time. Choose two if you want to record guitar and vocals together, or mic an amp and capture the DI simultaneously so you can reamp later.
