The best audio interface for guitar is one with a proper instrument-level (Hi-Z) input, clean preamps, and low round-trip latency so you can monitor and play in real time. For most home players a solid 2-in/2-out USB interface does everything you need, whether you go direct into amp sims or track a mic’d cab. This guide walks through exactly what to look for, then leaves room for current top picks.
Quick answer
- If you just want plug-and-play: a 2-channel USB interface with at least one Hi-Z instrument input and direct (zero-latency) monitoring.
- If you record amp sims/plugins: prioritise low round-trip latency and a stable driver.
- If you mic a real amp or track vocals too: get two good preamps and a quality headphone amp.
- If you reamp: look for a dedicated reamp/line output or a separate reamp box.
Why you need an audio interface for guitar
A guitar pickup puts out a weak, high-impedance signal. Plug it straight into a standard line input and you get a thin, dull tone with noise. A good audio interface for guitar fixes this with a Hi-Z instrument input that matches your pickups, converts the signal to digital cleanly, and feeds it into your DAW. From there you can run amp simulators, record a DI track to reamp later, or monitor a mic’d cabinet. If you are still deciding on the broader chain, our guide on audio interface vs mixer explains why an interface is usually the right call for recording.
How to choose an audio interface for guitar
Hi-Z / instrument inputs
This is the single most important feature. The input must be switchable to instrument (Hi-Z) mode, with an input impedance high enough (typically 1 MΩ or more) to let your passive pickups breathe. Without it, your tone loses top end and feel. Check how many of the inputs offer Hi-Z if you want to track two guitars or a guitar and bass at once.
Latency and drivers
If you monitor through amp sims, the delay between picking a note and hearing it (round-trip latency) has to be low enough to feel natural. Stable, well-written drivers matter more than raw specs here. Class-compliant USB and low buffer settings help, but the cleanest fix on most interfaces is direct hardware monitoring, which lets you hear your dry signal with no delay. Read our explainer on what audio latency is to understand the trade-offs before you buy.
Preamps and headroom
Even if you mostly go direct, decent preamps give you clean gain and headroom for hot pickups and active basses. If you also plan to mic an amp or record vocals, you want two transparent preamps with enough gain. Pair this with sensible levels — our gain staging guide shows how to set input gain so you capture a strong, clean signal without clipping.
Direct monitoring and headphone output
Direct (zero-latency) monitoring lets you hear yourself instantly while recording. A good, loud headphone output matters for late-night practice and tracking. Some interfaces add a blend knob so you can mix your live input against the playback from your DAW.
Connections and I/O count
Decide how many inputs you actually need. One Hi-Z input is enough for solo guitar into amp sims. Two inputs let you DI and mic at the same time, or record guitar plus a scratch vocal. Check the output count too if you want to reamp or run a separate monitor feed.
Reamping support
Reamping means recording a clean DI track, then sending it back out through a real amp later. For that you need a clean line/instrument output (or a small reamp box) and software routing. Not essential for everyone, but worth planning for if you love chasing amp tone.
Connection type: USB, USB-C or Thunderbolt
For guitar, USB or USB-C is plenty. Thunderbolt buys you lower latency at higher cost and is overkill for one or two channels. Make sure the interface is supported on your operating system — check macOS/Windows compatibility and whether it is bus-powered, which is handy for mobile rigs.
Direct (amp sims) vs mic’d amp
Two common workflows shape which interface suits you:
- Going direct into amp sims: you only need one great Hi-Z input and low latency. This is the easiest, quietest way to record at home and the focus of most beginner setups. See our walkthrough on how to record electric guitar for the full direct chain.
- Micing a real amp: you need a good preamp and a microphone, and you trade simplicity for the room sound of a real speaker. If you record steel-string or nylon guitars too, our guide to recording acoustic guitar covers mic choice and placement.
What you don’t need to overspend on
Don’t pay for eight channels you’ll never use, or chase boutique converter specs for a bedroom setup. For solo guitar tracking, a clean 2-channel interface with one or two Hi-Z inputs and reliable drivers outperforms a flashier unit you can’t drive properly. Spend the savings on a better cable, strings, or acoustic treatment.
Our top picks
Below are the interfaces we recommend for recording guitar at home, grouped by use case. Each pick is chosen for its instrument input quality, latency performance, and overall value.
Best overall audio interface for guitar
The all-rounder: one or two excellent Hi-Z inputs, low latency, solid drivers, and direct monitoring — the interface most guitarists should buy first.
Focusrite Scarlett 2i2
The Scarlett 2i2 is a 2-in/2-out USB-C interface and one of the most widely recommended starting points for home guitarists. It pairs a switchable instrument (Hi-Z) input with clean, low-noise preamps, reliable drivers and direct monitoring, so you can run amp sims or track a mic’d cab without fighting latency. It’s a great fit for anyone who wants a dependable do-everything box they won’t outgrow quickly.
Best budget pick
An affordable single-input option for players going direct into amp sims who want clean tone without spending much.
Focusrite Scarlett Solo
The Scarlett Solo strips the range down to one mic and one dedicated instrument input, which is exactly what a solo guitarist going direct into amp sims needs. It keeps the same clean preamp character and stable drivers as its bigger sibling in a smaller, cheaper, bus-powered package. A popular choice for first-time recordists who want quiet, full-bodied direct tone without paying for channels they won’t use.
Best for micing an amp (two preamps)
For tracking a mic’d cab, or guitar plus vocals, with two quality preamps and a strong headphone output.
Universal Audio Volt 276
The Volt 276 is a 2-in/2-out USB interface with two preamps, a built-in compressor and a vintage transformer-style mode that flatters both mic’d amps and vocals. The Hi-Z input handles guitar directly, and the strong headphone output makes it comfortable for tracking yourself or a singer. It’s a popular pick for players who want two channels with a bit of analogue character baked in.
Best for reamping and serious tone-chasers
A step up with clean line outputs and routing flexibility for capturing DI tracks and reamping through a real amp later.
MOTU M4
The MOTU M4 is a 4-in/4-out USB-C interface known for very low latency and clean, transparent converters, with two extra line outputs that make reamping a DI track through a real amp straightforward. The clear LCD metering helps you set strong levels on the way in. It’s a widely recommended choice for tone-chasers who track DI now and want the routing flexibility to experiment with amps later.
Setting it up
Once you’ve chosen, the rest is straightforward: install the driver, set your guitar input to instrument (Hi-Z) mode, dial in gain so peaks sit comfortably below clipping, and enable direct monitoring. Our step-by-step on how to set up an audio interface covers buffer sizes, monitoring and DAW routing. You can browse more gear guidance on the audio interfaces hub.
Frequently asked questions
Do I need a special audio interface to record guitar?
Not a special one, but you do need an interface with a Hi-Z (instrument) input. That input matches your guitar’s high-impedance pickups so you capture full, clean tone. Any quality interface with a switchable instrument input works well for guitar.
Can I record guitar with just a USB interface?
Yes. A standard USB or USB-C interface is more than enough for one or two channels of guitar. Thunderbolt offers slightly lower latency but is unnecessary for most home guitar recording, and a good USB unit with direct monitoring removes any noticeable delay.
How many inputs do I need for guitar?
One Hi-Z input is enough if you go direct into amp sims. Choose a 2-input interface if you want to DI and mic an amp at the same time, record guitar and a scratch vocal, or track two instruments together.
