Thank you for viewing. This is the KORG KR mini. It's a compact rhythm machine with intuitive operation buttons and various connection terminals. - Brand: KORG - Model Name: KRM-1 - Connection Terminals: Headphone jack, AUX jack - Color: Gray - Operation Buttons: Multiple operation buttons, knobs This is a convenient rhythm box that can be used with AA batteries. I haven't used it much, so there's only a little sign of use. I'm sorry, but due to the prevention of product replacement, returns and exchanges are not accepted. The following is from the Korg website: ------------------- In recent years, rhythm boxes and rhythm machines have become digital and multi-functional, and while you can create intricate patterns, the operation tends to become more complex. If you want to casually enjoy playing, and instead of a metronome in the background, you want to easily play authentic rhythm patterns... The KR mini, a rhythm box from Korg that has appeared after a long time, answers such requests. It has a nostalgic look and uses analog-like controls, with a simple design that eliminates complex functions. You can easily play rhythm phrases with intuitive operations: pressing pads, tapping, and turning knobs. The operation is simple, but there is no compromise on the sound. You can play with a total of 60 different rhythm phrases in the background. Easy, simple, and compact, the KR mini can be used anywhere, and is the rhythm box that many instrumentalists have been waiting for. ------------------- I will include the manual downloaded from the website. There is no original box. There were no original accessories.
