ToneStack is the ultimate UNIVERSAL app for signal processing: with the LARGEST and BEST selection of AMPS & FX, the latest advancements in modeling technology, and an unbelievably powerful yet simple interface – it simply shreds all the other guys. 

Thanks to ToneStack's state-of-the-art “Virtual Circuit” technology, each ToneStack unit is the digital mirror image of a real analog topology. Unlike other FX apps that try to copycat with EQing and other gimmicks, ToneStack recreates the intricate designs of the real thing. The result is a warm, responsive tone with the natural behavior you find in analog units.

Best Selection of Pro Amps & FX

ToneStack offers a huge range of amps, cabs & FX: from sparkly clean to sizzling hot bias tube amps, iconic stompboxes, pro-grade rack units, and high-end reverbs, ToneStack is the most complete plugin suite on the iOS.

Right away, enjoy 6 classic amps & cabs, and 21 meticulously designed FX. Expand to a total of 46 amps, 44 cabs, and 101 FX – the largest collection on iOS.

ToneStack also brings many powerful guitar FX to the iOS for the first time: polyphonic octaver, harmonizer, realistic spring reverbs, virtual-reel tape delays are just a few examples.

The Most Versatile Signal Chain on iOS

Why be limited with just 4 or 8 FX that other guys max you out at? ToneStack lets you run a whopping 64 amps & effects simultaneously* so you can let your imagination run wild.

For even more power, ToneStack includes our unique original ABY unit. Split your signal anywhere: run dual amp setups, switch or blend FX chains, or multiplex your signal via frequency splitting – countless permutations, all up to you.

You can match any amp with any cab (all cabs have 3 mics with distance & position settings); you can insert any unit anywhere – even between amps and cabs like a true FX loop. Managing your signal chain is as easy as dragging and dropping an icon!

inSTUDIO & Other Goodies

Wanna quickly jam out an idea, or cut a song and share it? ToneStack offers a powerful 8-Track recorder – first two tracks free — with plenty of user-friendly features. Fire up the built-in Tapedeck to quickly record an idea or create loops, or manipulate audio with its Hi-Q pitch & time shift. Import & export audio via email, WiFi, iTunes or copy/paste. Built-in tuner, metronome and a custom onSTAGE mode are just a few other amazing ToneStack features.

All the Pro Features of iOS

Enjoy the full power of the platform’s top MIDI and Preset systems. MIDI learn is super-intuitive thanks to ToneStack's WYSIWYG interface: all the amp & FX controls are MIDI-programmable. Effortlessly create UNLIMITED banks and presets – share them at the touch of a button. ToneStack is an Inter-App Audio effect, and works in any Audiobus slot. ToneStack also allows you to insert other Inter-App Audio apps anywhere in your signal chain.

Great app, some suggestions

Tonestack is a fantastic app, and the amps and effects sound great. A small but very useful feature is the detune mode on the tuner, so if you are playing along to a song that is tuned half a step down you can easily play in tune. Could a future update please include an ability to do this for each string individually, so you could play in drop D or even in open tunings without actually needing to retune your guitar? That would be awesome. Also, maybe throwing in more presets with future updates would be cool as they are good starting points and helpful to see how some of the more unusual pedals could be used in a musical way. Anyway great app and thoroughly recommended!

Stacks Of Tone

I downloaded TS Go for free... impressed.
I dropped £10 on the V3... floored.
I purchased the mother load for nearly £50...

Think my five stars says the rest. If not though, here's a quick review. BUY THIS APP!!!

Seriously folks, this app is awesome. The amps and cabs feel great, sound great, break up and squeeze in all the right places like a real amp should. You can tailor your tone and feel to go from soothing cleans to mental metal. And yes, it djents. Then there's the fx; two words... sublime. I know that's one word but the other one is a swear word that sounds like "ducking". ;)

You can look for comparisons from all the major players like Bias and AmpliTube but is it any better or worse? No... it's different and that's no bad thing. Sounds and feels great and that's enough. And I know good tone and should do after the years I've been playing.

Excellent app. Love most of the tones, some need a bit of work to get right, but persevere with it and you'll find the tones you're after. Good tape player for practice and excellent 8-track for recording. All in all, despite its slightly toy like appearance, just let your ears decide. Once you add a Blueboard, or similar, and an expression pedal it's a great setup.
