I have several tube amps that I needed to control the volume with at home during the pandemic with everyone home and finding limited time to play. The Waza TAE is great at taming the volume and getting great tone, either attenuated and reamped through the cabinet or via headphones. It also adds reverb and delays I don't have and allows me to record direct from the amps as well. I can also run my HX Stomp through the effects loop and amp the a cabinet which is something that I can't do with other products in this range. Overall its a fantastic product.

This product seems great but unfortunately I could not use all of its features because there's no support for OS X 10.11. When I asked Roland Support if I could be supplied a driver, all I got was the standard scripted "sorry for the inconvenience" and nonsense about OS X 10.11 no longer supported. Meanwhile, they have drivers for Windows 7, and ironically, have OS X 10.11 drivers for the Waza Amplifier and BOSS ES-5, 8 controllers. But what's especially infuriating... nowhere in the product's marketing materials nor specs are minimum systems requirements listed. So you spend over $1300 on something, find out it won't work with your system and what you get is "sorry...???" It wouldn't take much effort for a developer to put out a driver which, for a deprecated OS means they don't need to update it ever again... but goes to show that they'd rather say they're "sorry" because they don't care. So... I'm sending this back and to get my hard earned money back. If you're considering this unit make sure you read all of their fine print buried deep in their support sites, far from the glossy pictures and videos that demonstrate how wonderful their product is.
