Purchased from a used instrument store in June 2025. It's for a nylon-string guitar with an undersaddle (piezo) pickup. Operation has been confirmed. Everything in the photos is included. This is a compact preamp/DI specifically designed to blend 16 classical guitar modeling sounds and pickup sounds at your preferred ratio. It's no longer in production, so it's rarely available. The key to using it is to select the sound source from the 16 presets that best matches the sound of your own guitar. The sound sources are combinations of guitars and microphones. Recommended for those who want to make their current sound more natural.
