I just stumbled upon this old gem in my dad’s attic and I’m blown away by the sounds I’m getting out of it. The Quadraverb was definitely ahead of its time and it’s amazing to see how far reverb technology has come since then. Thanks for sharing this retro audio goodness, loved the post!
I have one of these units, it needs a look at, makes a noise, hard to describe it, you only hear it when you turn the amp up, i have the shadows on the 100 programs, some of them have been changed to the list i been given. want the original shadows added back. do not want to any factory reset i might lose them all together.
