The DigiTech RP3 is a multi-effects processor for guitar. This is a set of a guitar effects processor and a mini guitar amplifier. It has been stored at my parents' house for about 25 years. I have confirmed that both power on. Since I don't have any sound sources like electric or acoustic-electric guitars, I haven't been able to confirm their functionality. However, I don't remember them being broken. As they are vintage items, I cannot offer any guarantees, but please consider purchasing them with this understanding. Dust from 25 years has accumulated inside the amplifier speaker. I think it will disappear as you play it. The attache case containing the effects processor is from when I bought it, and I don't remember why I put it in there, but I will send it as is. Thank you. Addition: After checking the power several times, sometimes it turns on and sometimes it doesn't, possibly due to a contact issue. Even when the power is on, the display doesn't change when I press the buttons, so I don't think it's working properly. Therefore, I will relist it as a junk item. - Model: RP3 - Color: Yellow - Accessories: User guide - Type: Multi-effects processor - Brand: DigiTech Thank you for viewing.
