The Best Thing Going

Without a doubt the best thing going for iPhone and iPad. No fizz, no buzz, no flop. Great bottom end too. Use it with AUM and add stereo FX. Use it with JamUp for a mono live set up. Could have been five stars but updates are poorly quality controlled. They tend to fix one thing and break another. Get that together PG...PLEASE!

I have to pay for everything again?

So I’ve been using PG’s products for a long time now.

I have the Bias Mini Head, Bias FX for iPad & Mac, Bias Amp 2 for Mac, iPad & iPhone.

So I updated the apps on my iPad and Mac, paying for the extras on both platforms, amp packs, IR packs etc.

Then I updated Bias Amp 2 on my iPhone and was a bit upset to find that I needed to again pay to unlock everything that I had previously paid to unlock on my iPad.

And we’re not talking $20, it’s $14 for the 2.0 unlock, $9 for each of the amp packs, and $19 for the IR packs again.

I can understand paying for Mac and iPad, two entirely different platforms, but to have to pay for the licenses again on my iPhone after paying for everything on my iPad is milking your customers.

I won’t be repurchasing my licenses again for the iPhone and will be deleting the app since I don’t use it on my phone, it would have been useful to tweak my Mini Head, but I’ll just use my Mac and iPad, needless to say for a long time customer this is disappointing.

Bias Amp Mini 300 Head

I paid so much money through the App Store, and now can’t even see what I paid for. I put it on my iPad Pro, iPhone XS,Max,and another old iPad Air. Service is the worst. Can’t get through with ridiculous boxes you can’t even see what your choosing. If I don’t get help by the end of the week it’s going back to zZounds, and I’m going after Apple Store to get all the monies I spent. It worked at first but all this password nonsense is out of control. BTW teaching guitar for 35 years and still going strong. Was going to bring into my studio to show students what not to buy if they don’t rectify the problems by the end of the week. If I’m taken care of, I’ll do a revision.
