Customer Reviews

Jam Up Pro Rocks

I have Amplitube with all the options, as well as Ampkit+ and GarageBand, and while each has its pluses and minuses - more often than not I reach for Jam Up Pro. I'm a gear junkie in the real world, and I'm quite fond of the amp and effect models in Jam Up - the sound quality is excellent. The app may not have all the bells and whistles that a fully loaded Amplitube has, but its rock solid and far less finicky than the latter. Support is just as important as features in my book, and the single incident where I needed non-technical support left me scratching my head (surprised). I've purchased a considerable amount of software over the years, and I've NEVER had a vendor bend over backward to provide a solution the way Positive Grid did. Buy this app and as many expansion packs as you can - you won't regret it!

Great tool for musicians!

I use this app for playing live and for recording. The base app is not bad, but the expansions really open up amps that gets the right sound. (Recommend metal expansion and boutique expansion) I use an iRig pro and Blueboard for interface and preset changes. Once you dial in your tones with a pair of studio monitors this app sounds awesome for direct recording. I have yet to experience hissing our noise in higher gain settings. My only complaint is that the add ons are rather pricey...

Best Guitar App I've Seen

I've been playing for about 25years and have allot of software based and guitar apps. This is is the best sounding and easiest to use. Once I saw the web based commercial on the Internet, I had to get it. I got most of the value pack. The Metal and Rock packs are killer. Just plain and simple its incredibly sounding! Highly Recommend it.
