Top 3 Guitar App Posted by

Right now Jamup/Bias, Ampkit, and Tone Stack are the best amp simulators for iOS in my opinion. Each are outstanding in their own right and each bring something special to the table. Their are a few other apps around that sound darn good as well (Amplitube Hendrix, Flying Haggis, etc.) But it is hard to go wrong with the top three I have listed above. Bias on its own sounds terrific. The metal amps are killer in particular to my ears. Combined with Jam-up, Bias becomes almost an unstoppable monster. Why? Not every guitar will sound good with certain amps. With Bias you can dive in deep and tweak or create an amp or several amps that will sound good with the guitar you are using. When you are done tweaking you can load your custom amps into Jam-up to take advantage of all the additional features Jam-up offers. In summary, different people will like the sound of a particular product over another time an again. However, with Bias you can change the sound of the product in ways far beyond any guitar amp simulator I have found on iOS. It really does feel like having a custom amp workshop in your pocket. In this regard, it is hard to imagine that if someone spends some time with Bias, they will be unable to dial in a quality amp sound. It is that good!

Tone you can get inside of Posted by

Using apogee jam and 90s Japanese Fender Strat Input levels really change the character of the amps, so you may need to run the input levels fairly high, especially if the sound seems too clean and glassy. Also you may want to turn the "room control" room ambience off at first. I was crazy impressed by: The high detail and character in the sound, especially the warm tube sound. All of the stuff you could adjust and mess with that was much more than just eq. The huge variety of sounds you could get, from Marshall stack to Silvertone. The way you can get a high gain big distortion sound without harsh high end. The things I thought could be better: The "room control" reverb is really dark and tanky and mono. There is no reverb or tremelo in the amp models. The room reverb does not seem to interact with the mic position. It plays well with Garage Band by starting the audio recorder instrument then plumb in Bias with Inter App Audio. Then you can use Garage Band's really rich wide stereo reverb for a good room sound.

The best guitar app thus far Posted by

First off I will say I am NOT a fan of Jamup. Jamup was a great idea poorly executed. This app, Bias, is on the complete flip side. Yes, there are some digital artifacts, but minimal of all the apps I've seen so far. Also, if you disable your cellular data for all apps and disable wifi you will have less RF interference while playing. I play progressive metal and Djent. It took me about 5-10 minutes to dial up a tone I really liked vs Jamup which I have not found a solid amp. You can export your amp models to Jamup and they do sound much better than what in app purchases provide. The reason I rated 4 stars- tone qualify changes slightly and more background noise is present when you export to Jamup. I have emailed Positive Grid's support and they areole than willing to work with you on suggestions and troubleshooting. But the Bias app itself is everything I could have asked for in a portable practice setup. I am using it on my IPhone 5C with no issues. Great job on this one Positive Grid!

Pretty awesome app Posted by

I can't believe this thing sounds this good coming from my phone I never thought I would ever like anything like this. I know most guitarist put this app down but you know how guitarist are stuck on 1950's technology. Some of the few complains were that it feels like ever amp was design for modern metal or classic tube clean amps and nothing else. And the high gain was focus on low end I rather just use my my boss me 70 for lead solo. I wish they would have gave you crazy effects too instead of just basic effects. Another cool thing too is this thing actually sounds like an axe fx 2 on some of the tones. Who knows maybe people will be usein apps and tablets in bout 10 years for guitar tone and one more thing this thing sounds better than some of the actually gear I have which is pretty insane.

Yes, it works. Posted by

I have an iPhone 5c and use the jamup plug exclusively (for now). I run a Fender GLS into it, as well as an old '61 Norma, a Lanikai concert ukulele, an active Ibanez fretless whose model escapes me at the moment. They all sound as they should, amp models are accurate, tone shaping control is exceptional and the amps I create port into Jamup Pro XT as they should. I like to use in-ears most often. Regular earbuds work just fine as well. If I want to get loud I can run it to a plain old home stereo. It's a great app to have when you hit up the guitar shops to test instruments. No waiting for the stereotypical willy wanker to pipe down or begging for a cable from inattentive staff. (I'm not sayin, I'm just sayin)

Impressive Posted by

This is quite the amp modeling software. It's particularly impressive when the portable factor is taken into account. Garage Band has decent amp modeling, but nowhere near the tweak ability that BIAS has. The possibilities are nearly endless with the number of different tweaks that are available. Then there's the Tonecloud. If you don't want to make your own amp model, steal somebody else's. Easy. If you want a portable amp modeler, grab this before the price goes up.

Definition of guitar sound Posted by

I've been using software amp modeling since the early days. It never mattered what the brand was. It was always getting better and better. A little something was missing until Positive Grid didn't show up and nailed that what every guitarist was dreaming of. Arsenal of amps, pedals and tubes all in your pocket. Ready for stage, practice or studio! This is the definition of present and the future of the guitar sound. Get it right now!

AMAZING!!! Posted by

I'm kinda old school, and little behind the times and technology, but when I came across Bias Amp/FX in the App Store and they were doing a huge sale, like now, I decided to go for it.... Positive Grid has TOTALLY nailed it!!! Fast forward a couple of months and I decided to get the Pro Desktop version, another huge sale, I got it all... I'm speechless!!! I can't wait to see what they have for me next!!!

Required update non existent Posted by

Downloaded a few tones from the cloud and was and to preview their sound but after I went to downloads I can't select them. I was under the impression that I had to buy the amp packs which I bought 2. Still unable to use them. Disappointing as they sound good with my guitar. I can't delete them either. When I try to select the amps in prompted to go to the website and update the app but it does nothing.

Love it, wish for ir and fx Posted by

Excellent app, sounds great and fun to use. I just wish it could load ir files like the desktop version. Also, I have bias fx but there's no iPhone version of it which is a bummer to me. Lastly, I'm not a metal guy and this app and company seems to be almost entirely driven by that group. It's fine, but I'd love to see stuff for other genres more prominent in the overall brand. Great work!

Love this app, but it has some issues Posted by

This app is amazing. I sold my expensive processor unit, because this app covers my practice needs, while the desktop versions covers recording. The only problem I've encountered so far is that when I tried to sign in to the tone cloud with this app - it crashed and now I can't even launch it. That's sad, I hope it'll be addressed eventually.

Great tones and tweakability Posted by

This is my favorite guitar amp sim. Along with JamUp pro for the fx, just great tones throughout. The ability to "mod" many different aspects of your pre and power amp sections is what makes this amp sim stand apart for all the others. A must have for players that want the best tones outside of actually playing a great tube amp....Bias is it!

Raised the bar again!! Posted by

I've seen it in the ads. I've noticed in was on iPads. And now, finally, it's on my iPhone! Perhaps the best $5 I have spent in a very long time. This app takes your guitar tone to where your imagination can reach. I can custom design my own amp, AND, drag it into my JamUp app. You will not be disappointed. Buy It!!

Sick tone Posted by

Omg.. Playing for 20 years, would never have imagined I could dial in master of puppets tone on my phone... Sick! Be aware as I see at least one other wasn't. This is the tone engine, and will not have fx... but does have amazing tone. It does also integrate with another program, that you can run fx with. Great job!!

Great APP - but still glitches Posted by

The app is amazing.... but it seems to glitch when you go from BIAS to Jamup Pro and then back to BIAS to choose another amp. The amp selections are blank besides the one your originallly chose. This might be an iOS 8 issue..... but i've contacted support and still waiting for a reply. I'm on an iphone 5s

I wouldn't have even dreamed.. Posted by

This app is all that and more! It lets you do things that would otherwise be impossible! And is as easy as playing Angry Birds! This and Jamup are gonna make me break down and buy an Ipad. Just get it!

Excellent amp modeler. Posted by

Now Bias is even more portable with the new iPhone version. Get great tones for guitar and bass and take them with you to gig. Now I have my AC30 with me anywhere I go. A must buy for any musician.

Amazing Posted by

Sound quality, variety and versatility are the best on the market for the price. No crashes on iOS 8.1 iPhone 5S.

greenirani Posted by

Thanks for making it available for iphone. waiting for your mastering app and wishing it would be universal

Incredible Posted by

I can hardly believe this is on my iPhone; yet it is! Truly incredible. Thank you, devs!

Stay away from the in app purchases by Chrismilnem 2015-08-07

It's the best sounding modeler I've heard, unfortunately the in app purchases are not worth it. To start with, though they don't tell you, you can't share them between your iPhone and iPad. That's like buying an upgrade on your desktop and not being able to use it on your laptop. Also the in app purchases show up in your custom section along side all of the time cloud downloads and as far as I could tell so far the new cabinets can't be shared with all of the app default amps. It seems the expansion packs are more like patches than new amps. I tried using bias with bias fx on an iPad 2 and it's a constant clipping/dropout situation. The same goes for audiobus and these apps, so you want the latest iPad.

Currently not working on iPhone 5... by KcilsMcAwsum 2014-02-25

I had trouble with iPad version of BIAS and it's not working properly with iPhone version either. It does not make any noise in the BIAS app, but it works when you port the amp to Jamup XT. Perhaps adding output selection would solve this. I don't think the Jamup Plug is to blame because it works perfectly fine in Jamup XT. I will be glad to change the rating once this issue has been acknowledged and fixed. Another $8 that has seemingly gone to waste for now. Hopefully a fix will make my $28 (iPad version added) spent on these apps worth it. Also, I felt like most of the 5 star reviews as of now were not from ordinary customer; meaning they are associated with Positive Grid.

Great, but flawed by polaris20 2016-09-06

This is kind of a blanket review for the iOS versions and the desktop version. They all sound great, and are infinitely tweakable. BUT..... They're all buggy as hell. When I create a preset on the desktop, I should be able to upload it to Tonecloud, then login on my phone, sign in, and see that preset. Instead, I have to search for it. When I try to download it, it doesn't work; says I need a newer version of the software, of which there isn't one. Get these little problems sorted, Positive Grid. It's annoying to see you roll out product after product, but not fix the bugs in the current products.

Worst VST EVER by DeepestShadeOfJaded 2015-12-17

I bought this and seen it on countless YouTube videos being remarked as something useful with decent sound and well went to check it out. I bought the iRig 2 as well and came in plugged it in and when I was ready, horrible sound came out. Too much feed back,too much distortion, the sound wasn't anything good and it sounded like I was playing diarrhea. The Line 6 Spider sounds better than this to say the least. One of the worst purchases ever.

Weird artifacts, distortions etc by chromaticbird 2015-02-05

For some reason I can't get this software to work as I'm imagining it should. I've tried two different electric guitars,3 different cables, double and triple checked my connections and there's still a lot of crap in there in the signal. I've played guitar since 1975 so I know what it's supposed to sound like. I have an iPhone 6 and the Jamup interface with an apple converter so it will work on newer iPhones.

This update killed custom panel graphics by TheRealDutchee 2015-06-05

No longer will any imported custom panel graphics display or save properly. Even all graphics from the Strandberg panels have disappeared showing incomplete amp panels. Same thing happens when exporting the Bias models to JamUp Pro... The custom graphics will no longer show up there either. This all worked fine until the latest update.

so much potential by dirt_mound 2016-06-03

I wish I could make better use of this app, but I am getting periodic pops, clicks, and dropouts in the audio every few minutes. the normal and low latency modes are both affected. using an iPhone SE with no other applications running. when it is working, it sounds awesome, but it is not useful for anything more than practice.

Unusable by Allan H. 2015-12-20

Just horrible. Not usable at all. Tremolo sound that won't go away and glitchy digital clipping. Can't even check out amp models. Using iRig iStomp. Booo hiss I want my money back.

Money Back??? Bait and switch by movie rater guy 2014-03-17

I had it for 3 days or so on my iPhone 4...and now after an update it's gone! Only works on iPhone 4s or newer after the last update. Bull!&[email protected] I want my $10 returned please.

Dissatisfied by JoeyGuitar777 2015-10-19

Needs a TON of work, not even close to a real amp or axe fx like they describe, I've tried everything in this app and still after months can not even get a decent tone

Good idea, horrible delivery by SalesTorch 2017-03-19

Product does not work like promised in videos. You cannot get he hissing and squeak out not matter how you adjust settings. Avoid this app

Please update by Bigdaddy87 2014-10-13

Nice app, but Audiobus connectivity does not work. Until it does this is pretty much useless for me.

Won't run on OS 9.1 by Seanxwtysw 2015-11-29

Won't run on OS 9.1 on my Ipad or my iPhone 6. Just freezes when its opened and does nothing.
