Absolutely!  The Fusion is amazingly versatile and has 3 output jacks:
¼” standard guitar output (like a normal electric guitar), with no iPhone effects processing, which can be connected to a traditional guitar amp.
¼” line out with the iPhone processed amp tones and effects, which can be used to connect to a PA, powered speakers or a standard guitar amp using a standard guitar cable. This is great for bigger gigs, you only have to take along your Fusion and a guitar cable and plug straight into the venue PA. This Line-out can also go straight into a studio desk for direct recording.
3.5mm stereo output for connection to headphones (for silent playing) or an external audio system.
Connecting to any of the 3 outputs will switch off the Fusion’s internal amp and speakers.
