Turn your iPhone or iPad into a guitar rig. Simple NAM Chain plays amp captures in the Neural Amp Modeler format, including A1 and A2. Load a capture, add a cabinet impulse response, and play. It runs on its own, or as an Audio Unit inside GarageBand, AUM and other hosts. BUILD A CHAIN Stack up to six blocks in series — a drive pedal into an amp head into a cab, or whatever order you want. Drag to reorder, bypass any block, remove the ones you don't need. Tag each one Full Rig, Amp Head, Pedal, Outboard or IR so the chain reads at a glance. EVERY BLOCK IS A FULL RIG Each block has its own input level, noise gate, amp capture, cabinet IR, three-band EQ and output level. The gate, the EQ and the IR each switch off independently. LOAD WHOLE MODEL PACKS Captures usually arrive as a folder holding the same amp at a range of settings. Point the app at the folder and step through every capture with the arrows, without going back to a file browser between takes. Keep your packs anywhere on the device, or drop them into the Full Rig, Amp Head, Pedal, Outboard and IR folders the app creates for you in Files. GAIN STAGING HANDLED Captures that carry calibration data are gain-staged automatically as you reorder the chain, so stacking blocks doesn't wreck your levels. Set your interface's input level in dBu once, and pick Raw, Normalized or Calibrated output. ALSO INCLUDED • Built-in tuner • Slim control, to trade a little accuracy for lower CPU on captures that support it • Live CPU readout • Recovers cleanly from phone calls, route changes and unplugged interfaces WHAT YOU NEED An audio interface to plug your guitar into gives the best results — the built-in microphone works, but isn't meant for playing. You'll need captures in .nam format (A1 and A2 are both supported), and impulse responses as .wav files if you want cabinets; thousands are free at tone3000.com. Headphones or monitors, so the mic doesn't feed back. FREE FOR THREE DAYS Everything is unlocked for three days. After that the app stops processing audio until you unlock it, which is a single payment of $4.99. Not a subscription, no accounts, no ads, and nothing is collected about you.

Every guitarist knows the moment: a tone comes on and you have to know how it was made. ToneDNA listens to the recording and builds the answer - a complete, playable signal chain, matched to your guitar, in about a minute. HOW IT WORKS 1. HEAR IT - Load a song, or capture audio playing on your device. Working from a full mix? ToneDNA can isolate the guitar first. 2. BUILD IT - The matcher auditions hundreds of rigs against the recording, derives a speaker cabinet from the sound itself, and fits every level to a capture of your own dry playing - so the rig is tuned to your guitar and your hands, not a generic profile. 3. PLAY IT - Plug in and play through the result live, with latency low enough to gig on. WHAT GETS BUILT - Amp voicings from clean American sparkle to modern high gain - Drive, fuzz, boost and compressor pedals - stacked the way the matcher hears them on the record - Delays with tape character, reverbs, chorus, flanger, phaser, tremolo and rotary - A speaker cabinet derived from the recording itself - Stereo width measured from the record's own ambience Where a recording's rig is well documented, ToneDNA starts from the circuits the record actually used and fits every level from your playing - and the saved preset says so. MAKE IT YOURS Every block in the chain is open: tweak drive, swap the amp, pull a delay back, or remove what you don't need. Save the rig, tag it, and build set lists. ON STAGE Perform mode puts one song at a time in front of you - big type, next/previous, a tuner and a bypass, nothing to fumble. Step through your set from the screen or a MIDI controller, wired or Bluetooth. TUNED TO YOUR GUITAR A ten-second dry capture is all it takes, and your playing never leaves the device - the matching runs on your own hardware. Working from a full mix, the span you mark is sent up to isolate the guitar; it is held in memory only and never stored. Looking up a record's documented rig sends the song and artist, never audio. WHAT IT COSTS One Tone Scan builds one rig. Three are included to start, and more come in one-time packs - no subscriptions. Every rig you build is yours to keep, edit and play forever. GOOD TO KNOW - A USB audio interface is the way to play live through ToneDNA; the app is fully usable without one for building rigs and browsing them. - iPhone, iPad and Mac.
