Why does bias FX sound bad?
Just mess with all of the different volumes and levels of the inputs, outputs, and the amp itself on both the software and hardware side. That's usually the main culprit of poor sounds.
Can you upgrade bias FX?
If you own the standard version of any of our BIAS FX or BIAS Amp plugin, you can upgrade to the Professional version for the difference in what you paid for your version, and the PRO version. In most cases this will be $100. You will see this price displayed while logged into our Store.
