Input: AC100-240V 50/60Hz Compatible models: Blackstar Fly 3 Blackstar Fly 3 Bluetooth Blackstar Fly 3 Bass Blackstar Fly 3 Acoustic *Does not work with the larger Blackstar Superfly ** Also we've had a few customers contact us about the LED light not working. The power supply case has a lens for an LED light but the circuit does not have a an LED light inside. So this is normal for there to be no light coming through the lens.
