Quick verdict
The Scarlett Solo 4th Gen is a sensible default for a guitarist or singer who records alone and does not need two microphone preamps. Its dedicated instrument input, improved 57 dB mic gain range, Air modes, loopback and strong headphone section cover the practical needs of demos, lessons, song ideas and finished home recordings. The reason not to buy it is channel count: anyone expecting stereo microphones, two vocal mics or frequent two-person sessions should step up to a 2i2-class interface.
Market check
Scarlett Solo is one of Focusrite's core entry-level interfaces and the 4th Gen exact ASIN has maintained strong Amazon-market demand. Focusrite continues to update the 4th Gen documentation and software ecosystem. The page deliberately sends buyers to the exact ASIN for live seller, price and stock rather than displaying a volatile price.

Real-world fit
Where this product makes sense
Guitar + vocal demos
The dedicated instrument input and microphone preamp are a natural fit for a singer-guitarist building tracks one source at a time.
Amp-sim recording
Plug an electric guitar directly into the instrument input and monitor software amp/effect chains through headphones or studio monitors.
Streaming and lessons
Loopback makes it easier to route computer audio alongside an input for streaming, tutorials and online lesson workflows.
Selection notes
What stands out
- The Solo is intentionally optimized for one-person recording; channel count is the main buying decision, not converter quality alone.
- Focusrite's Air modes alter the preamp response to add presence or harmonic character, giving users a choice beyond a neutral input path.
- A dedicated front-panel headphone level and improved headphone performance make it practical for silent tracking and editing.
- The included software bundle changes over time, so check Focusrite's current bundle rather than buying solely for one named plugin.

FAQ
Questions worth answering first
Can the Scarlett Solo record guitar directly?
Yes. The front instrument input is designed for direct guitar or bass connection and can feed a DAW or amp-simulation software.
Can it record a microphone and guitar at the same time?
Yes, using the microphone input and dedicated instrument input simultaneously. It still has only one microphone preamp, so two-mic sessions require a larger interface.
Does the Solo provide phantom power?
Yes. It provides 48V phantom power for condenser microphones that require it.
