The Zoom G1X Four is a small affordable and low budget package, with a great deal of potential functionality. 70 built-in effects, 13 amp models, an expression pedal, and a built-in looper and drum machine,  it's an impressive practice tool, especially if you're a beginner or new to the world of effects.

Sounds

There's plenty to explore in the G1X Four with over 70 effects to play with. You've got your classic effects such as overdrive, compression, and fuzz; but you also get crazier effects like ring modulator, pitch-shifting delay, and sitar simulation.

The built-in expression pedal gives you even more control over your sounds allowing you to smoothly adjust volume, delay, pitch or wah with your foot. You can string up to five effects together in an order of your choosing and you can also edit effects to shape the exact sound you want.

In addition to the wide array of effects available, you also have access to to 13 different amp models. The models are designed to emulate classic amps & cabs from classic brands such as Fender, Marshall, Orange, and more. If that's still not enough sounds for you, you can also take advantage Zoom's free Guitar Lab software which gives you access to loads of artist patches, effects, and more.

Functionality

Effects and amp models are awesome, but the G1X Four is more than just a load of sounds in a box. It may not be the most exciting thing but the built-in tuner is a very useful feature, because no matter how many effects you use, it won't sound good if you're out of tune! The built-in drum machine offers 68 rhythm patterns with various time signatures, not only does it give you a backing to play along with, it'll also help you with your rhythm and timing.

The built-in looper is another great function which allows you to record up to 30 second of playing and then loops it, allowing you to create multi-part arrangements. Why spend ages looking for a backing track when you could make your own!

Other useful features include 50 memory locations for user-created patches and auto patch backup which saves your patch and level settings. So you when you find a sound you love you won't lose it! 

While the G1X Four is great for practice you can also use it for live performances. You can switch between sounds smoothly using the two performance modes, the Preselect mode allows you to jump between patches without affecting your current patch, and Stomp mode lets you turn on/off individual effects.
