Not just for AER amps! I always wondered why many floor wedges aim the sound at performers knees... The AER tilt allows you to tilt the monitor up, so it's pointing directly at you. This means you can have it quieter, which is better for everyone... It folds flat when not in use so it should slip into the monitor bag easy enough. We also use these under bass and guitar amps, to tilt them back a little (make sure they're not going to fall backwards!) so you're not just using your legs to hear your tone. Very hardwearing, you'll wonder how you ever managed without one.
Use this simple to put together support under your amplifier and your tone and volume will cut through the mix and get out there so much better or place it under your monitor and you will enjoy listening to yourself even better! Folds flat for the gig bag and opens out and sticks together in seconds very securely. Recommended.
