I'm selling this because I'm reorganizing my equipment, which I purchased about a year and a half ago. Please note that the DC power cable is missing. Please prepare one at the time of purchase. Although I lost the power supply before, I have confirmed that all functions are working properly. If there are any issues, I will be happy to assist you even after the purchase. There is Velcro attached to the back from when I created a board. I apologize for this. I have registered the Tonex product, but I understand that user registration is possible on multiple devices. Please refer to the official website for details and make your own decision before purchasing. I cannot be certain, so I appreciate your understanding... I'm sorry! TONEX effector with a variety of effects and parameter adjustments. - Model: TONEX - Parameters: GAIN, BASS, MID, TREBLE, REVERB, COMPRESSOR, MODULATION, DELAY - Bank Functions: A/B/C, BANK DOWN, BANK UP Thank you for looking.
