Own Want Buy Buy

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 39 amps, 38 cabs, and 85 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.
