Wish I had read Reviews before Jumping the Gun

First of all, I'm a pretty straight forward no BS all Analog/ Tube amp guy. I've been playing guitar for 37 years. I was looking for something that was user friendly, and sounded close to the real thing for practicing and recording. I downloaded the Elite Bundle because I didn't want to miss out on the great deal. I started uploading presets of some of my favorite artists and a few of them kept crashing, and a bunch of the other ones just sounded Horrible! I mean C'mon!!! As a Guitarist, I want to be inspired to play not sit there for an hour trying to figure out how to dial in the 200 effects and Amps. Frankly only a few FX and Amps sound decent, the rest are just fillers that I would never use. The customer service is absolutely Awful, I emailed them about their products, and they never answer all my questions. I have to keep sending emails and keep waiting several days before they answer back. If I had known that the Spark Amp that I've been patiently waiting for since December came with all the effects, I would have just waited before wasting $50 on this lousy app. This is very disappointing and I really wished that they would just wait till they put something worthy before releasing a bunch of Crap. Keep your hard earned money and look elsewhere.

Can’t transfer anything. Sound wise, not an upgrade so far.

I’ve been using Positive Grid’s products since very literally their very first releases way back in my iPad 4. I’ve made a lot of purchases of amps and effects on BIAS FX as well as other PG products. Just downloaded BIAS FX2 and used the ‘transfer license’ option, but nothing is transferred. I found out only PACKS will transfer, so those of us that purchased individual amps and effects are S.O.L. Thanks, Positive Grid, but I DO own several packs. None transferred after repeated attempts. I never expect great software to be free, nor should it ever be. However I felt this license transfer option is heavily broken. Nevertheless, I tried FX2 and so far hear no real improvement. That’s not to say it’s not good. It still has the course feel of previous PG amp modeling efforts, though the tone itself is fairly good if you dig deep enough.

I’m not interested in re-purchasing amps and effects I already gave PG money for. Also, above all, this product thus far does not present the impression of a completed, ready-for-release package. I just don’t see any upgrade here at all.

Developer Response ,

BIAS FX 2 is a brand new product of its own, with renewed algorithms and expanded functionalities, thus a separate purchase is required.

While the expansion packs from BIAS FX 1 Mobile can be carried over to BIAS FX 2 Mobile, the license from BIAS FX 1 cannot be carried over, meaning that a separate purchase has to be made in order to unlock the full functionalities of BIAS FX 2 Mobile.

Was worried about other negative reviews

I’ll say that this is my first purchase of Bias FX; however, I had one of the lower level Bias Amp packages and am somewhat familiar with Positive Grid’s products.

I was surprised to see all of the one star reviews, but after reading, the majority were about lack of support in Bias FX 2 of previous purchases. I totally get that but will say this product sounds pretty amazing. I’m using another company’s modeling product on my Mac, which I thought was good but now Bias FX 2 mobile may become my go-to modeler.

It really is easy to use (some crashing issues on first version - but that happens sometime with new software). I’m using an IRig HD interface into my iPad Pro and am pretty happy. Simple setup for jamming at home.
