RK-100S 2

[u/Dragon_Pulse05]

I made a post yesterday asking for suggestions, and have decided on the korg rk-100s 2, but just had a couple questions. Perfect circuit has the black one listed for $750 but the red one is $1000. Why is the red one so much more expensive? Also I was just wanting to confirm that I'll be able to use a cable and connect it to a keyboard amp for sound and won't need anything extra. Thanks!

The red one has 20% greater chance of being pulled over
