Great device for many songs! Well designed. Can leave it on forever, turn it of when I don't need it and use when I want. I just love it. Try 'Wild horses"from the Stones in G-tuning. Amazing!

What an awesome design! quality engineered and easy for amateur to fit. If your a fan of 60s folk music, or the Byrds and don't want' to buy another guitar to get the 12 string sound, then this is simply the best addition to a 6 string guitar of the century. Roger (Jim) Mcguin ex Bryds founder has a signature Martin acoutistic 7 string made to his specs, it is awesome, but for an amateur probably can't justify the $. Don't despair, check out the Addstring 🙂 I ordered mine from Australia, purchase was easy online and it arrived in post perfect. Very happy, thanks

The Addstring is amazing! For me it's one of the coolest inventions in the guitarworld at this moment. it's so simple to add the string. In less then 5 minutes you have one extra string on your guitar but it sounds like a 12 string! Amazingly rich and hamonious sound! I think I can't play without it anymore. check it out!!!

Easily fitted and seems a well made piece of kit. Though I wouldn't say a full 12 string, it certainly fills out the sound in a most satisfying way. I surprised at how well the device for tucking the string away when it's not required works (I wasn't so sure that would work before I got it). All in all, most satisfied

Hello, I am very happy and satisfied, the Add string is perfect. I like this sound like '12 string guitar' and the option 6 or 7 string is very very fantastic. I put the Add string on my Taylor guitar, and this acoustic sound is PERFECT. Thank you very very much. Best Regards. Virgil (Helene is my wife, and your mail box)
