Because I can’t even test it out before dropping $150.00, just to see if it’s a waist or not. The app pops up… Can’t play/hear anything while using the app. Also… I’m left handed. You don’t sell left handed models? Okay. ### 5/5 — Excelente top notch AUUG *2022-04-10, version 1.4.2* AMIGOS … pónganse TRUCHAS 😉, se acabaron los fallidos intentos por lograr ser músico PROFESIONAL , con AUUG todo lo que desees lo lograrás y sin PAGAR ALTAS CUOTAS A burdas ACADEMIAS, PERFECTO AL CIEN 💯 Y MUY SIMPLE , gracias mil ### 4/5 — Amazing *2022-03-06, version 1.4.2* Just like any instrument. There is a learning curve. The more I play with the better I get the feel of how to use the tool. Very fun to just pull out my phone and do a little thing for the kids and fam. Join in on friends playing the guitar or to just relax and play a chord and work to find the feel and note. Super well done. Have to get the grip to this app asap. ### 1/5 — Scam? *2022-02-27, version 1.4.2* So it tends to play a classic symphony instead of giving the user freedom to create your own. ### 1/5 — Doesn’t work no sound when i press *2022-01-18, version 1.4.2* Doesn’t work no sound when i press ### 5/5 — Nice Tool *2022-01-16, version 1.4.2* Just tried it out.
