"For sale is a wonderful vintage Korg MiniPops Junior analogue drum machine in nearly mint condition – it works perfectly, sounds absolutely awesome, and even comes in its original box! It has a punchy, warm transistor tonality with a massive hefty kick drum. There are ten onboard preset patterns, some of which are very usable indeed (the Rock, Mambo and Latin are my particular favourites); the kit pieces played in the patterns comprise Kick, Snare, Hats, and high and low percussion (kind of agogo-style).
It has a standard quarter-inch jack output so is ready to plug straight into your rig, and you could either use the patterns as-is or sample them and chop them up in your DAW (which is a great way to isolate the component kit pieces and have fun with them).The physical condition of the machine is amazing given its age: very, very little wear is visible. The veneer is unchipped, the front fascia is bright and smooth without scratches, and the start-stop lever is intact (often these got snapped off); please take a look at the photos to see how well preserved this is for an old piece of kit. The sound too is spot on: no crackles or issues, the patterns are punchy and tight, bass extension is wonderful... it sounds great :-) I've never seen a piece of vintage kit in quite as good shape as this – definitely collector's grade."
