I'm sad to see this go. The learning curve is worth it; it's rare, powerful, and an amazing mastering effects processor that would bless any home or professional studio. That's why it's still just as relevant in 2026 as it was in 1994. I've priced it because I kinda desperately want it not to sell... but I've got rent to pay :( It's worth every penny though.

I'm sure if you're reading this, you've probably done your research. But I've included an in-depth review video of it in operation (not mine), and below are the usual Googled description and basic specs:
