VOX Headphone Guitar Amplifier Clean (AP2-CL) I purchased this to practice with a travel guitar (silent guitar) while monitoring with headphones. You can enjoy sounds from acoustic to those with effects. I am selling it because I purchased a different system. I have misplaced the instruction manual, so I will include a copy. There are no operational issues, such as problems with plug rotation, defects, battery leakage, scratches, or scuffs. It runs on two AAA batteries. I will remove the batteries for safety and include them for operational testing. [Shipping] I will ship via Takkyubin Compact. I try to ship as quickly as possible, but there may be delays due to work. Also, I may use recycled materials for packaging (e.g., cushioning). Thank you for your understanding. I will waterproof it with plastic and take measures to prevent damage before shipping.
