This is a YAMAHA SA-RR custom. The Yamaha original body design, like the SA-15 and SA-15D, is very interesting, and I think many people are looking for these guitars. I've owned the above three models, and the SA-RR is by far the most practical, in my opinion. I've also seen videos of this model being introduced on YouTube. It's very unique, with a Telecaster-type bridge and a piezo pickup. I've confirmed that it produces sound through an amplifier, but I'm not very familiar with the controls, so I can't determine if they are functioning correctly. Please understand this. I usually only use it for its acoustic sound. The string height is low, making it very easy to play. I'd like to keep it, but I'm selling it to focus on acoustic guitars. A YAMAHA soft case is included. This model is now priced over 150,000 yen in guitar shops. If you're looking for one, please consider it.
