I'm planning to buy this unit. Has anyone used it before? Sounds really good in videos, has a valve tube but at the same time I dug deeper into the reviews and all the bad things. One of the things that really caught my attention was - there's a led light right under the tube to make it look like it's lit. I use avalon 737sp vt in my studio. That's a vacuum tube, it needs some time to light for the best recording texture or just to work fully. I just want to know if the Blackstar HT Dual pedal is for real? Or it's just a marketing stunt they've been pulling under our noses?
