Thank you for viewing. I am selling the mini guitar amplifier AROMA AG-03M with recording function. I acquired this a few years ago while looking for an amplifier with a recording function. While the specifications are not up to par with current amplifiers, I believe those with recording functions are rare. Recordings are saved on a microSD card and can be processed with PC software. It has the minimum specifications as a guitar amplifier. The following will be included in the original box: * Main unit: Aroma AG-03M * Charging cord: USB typeA-microB * microSD card 16GB (inserted in the main unit) * Instruction manual (English/Chinese) + Japanese instruction memo ※ It has been used with care, so there is no damage. ※ It's difficult to understand from the manual, so it's faster to try it out. ※ Usage information can be found on YouTube.
