Good to know
- The AD-16 power adapter is not in the box (as our title says, sold without adapter); the pedal also runs on 4 AA batteries or USB power.
- Use a USB cable that supports data transfer for Guitar Lab – a charge-only cable only gives power.
- Plug headphones into the output jack for silent practice.
