Fine-tuning your sound is a simple affair thanks to all the buttons and dials at your disposal. There’s one 1/4-inch jack for your instrument cable to the left of the analog control knobs, with 1/8-inch jacks to the far right for plugging in a set of headphones or wired sound source.
The Mustang GT amps also function like a big Bluetooth speaker. I was able to connect to the 200 and play some of the songs my band covers via Spotify, then play my guitar along with them to practice my solos and various parts. While I’d never recommend an $800 amp to just play music through, you might as well if you’ve already got one. The sound is relatively flat without any color, as it’s acting more like a studio monitor when you’re playing music through it. If you like your tunes with a bit more bass or treble, you’ll have to use your music player’s EQ settings, as the physical controls on the amplifier only affect the guitar sound, not that of any streaming audio.
The rear of both the 100 and 200 amps has a balanced set of left and right XLR line out jacks, a micro-USB port to connect to your computer for recording, and two sets of jacks for an effects loop (if you need to add even more guitar effects to the end your signal chain). The GT 200 comes with a four-button foot switch, also available separately for the GT 40 and 100 models. Being able to control the amp with a foot switch is all kinds of great, but it’s limited. Quick Access mode only gives you the ability to switch among three presets from your amp, though you can assign any three of the 100 included presets you like (plus any of your own creations).
Presets mode, as you might guess, lets you scroll through all the presets — but in groups of three only. In other words, you can have presets 1-3 enabled on three of the foot switches, but then you have to depress the right two pedal buttons to put the switch into scroll mode, then choose the next three presets, 4-7, or press two buttons again to cycle to 8-10. It’s…
