If you want to plug your guitar into your Mac, PC, or Android USB OTG device, then the Behringer Guitar Link UCG102 USB interface will get the job done cheaply.
First up I need to point out that this is one of those Behringer devices which saves you money, but doesn't offer a full set of features you would need for professional recording - the main drawback of the Guitar Link UCG102 is that it only has a 16-bit A/D converter.
While this is sub-standard when it comes to serious recording, it's perfectly fine for live performance, practicing, and personal recording.
When I say cheap I mean it - the list price is $49.99 but most online retailers sell it for just $39.99.
Although I'm not a huge fan of the UGC102 myself because it's not suitable for professional recording, I recognize that many people like the sound it produces - the following viedo review is typical of what many hobby guitarists have to say about it:
- Perfect for use with Android devices which support USB On-the-go (USB OTG)
- Mac and PC compatibility allows both Mac and PC owners to use this device
- It includes a free limited version of Native Instruments “AC Box Guitar Combo” - for VOX AC30 Simulation
- A 1/4” stereo headphone and volume dial to help you practice your jamming sessions without creating noise
- Three amp models are included with the Guitar Link
- Powered through USB – you require no additional power supply
- Play-back function for MP3, WAV, AIFF audio files, which allow you to practice easily
- Works well in XP, Vista and Windows 7
- Includes Tracktion 4 - a simple but effective single window DAW
- Easy to use
- Inexpensive interface
- Zero latency issues
- Only 16-bit depth
- Limited support from manufacturer
- Not suitable for professional recording
- Many guitarists will quickly grow tired of the bundled software and want something better.
- Windows 8 is not officially supported and Behringer does not provide Windows 8 drivers
If you want to have a bit of fun plugging your guitar into your computer, then go ahead and get the UCG102, however if you're serious about recording then a least step up to something more suitable like the Peavey AmpKit LiNK HD instead.
