I went to see if there was some sort of Bias Pedal I could run in my Helix's FX loop so I could have my favorite Bias amps and not only did that not exist, they didnt have heads on there anymore either!
I’ve never seen any Positive Grid hardware in the wild, except for the Spark, which I think sounds like shit. And after spending a ton of money for some reason on their shit plug-ins, I’ll never give them another dime.
In case they treat their hardware QA the same way as their software, I wouldn't even take one of their offerings for free.
Right now a local shop is selling the Bias Head for €449, list price is around €1250 or so - should tell you something.
