More of a Sample playback instrument but It’s great for MIDI control… chords are possible but a pain IMO. You also might consider Thumbjam … and go on a hunt for the right sounds. The old standbys Guitar and Shred by Frontier are still the best soloing apps … please someone correct me if I’m wrong … But they may not even be in the store these days, and don’t support AudioBus or MIDI. Other than that the Garage Band has really nice guitar instruments but no way to use them outside,of the App. MIDI activation might be an IAP too… Not expensive though. It has MIDI out which actually works … A 3 channel solution which let’s you select channels for chords, notes, and bass note separately. It plays chords, and tapped notes wonderfully … though there’s no scale/ solo mode, so you are limited by the notes within chords. Effects and amp models by AUFX ( good) are also available if you don’t want to use other third party solutions. It has a great acoustic guitar out of the box, then other guitars as IAP,s… Electric, 12 strings etc. Get those classic sounding guitar riffs and find the perfect starting point for. Without hesitation I recommend Guitarism by Rhism. The guitar is an iconic instrument, so why not sample it in your music.
