Roland JX-305 (It's like an R2 Unit)


"The JX-305 Groovesynth debut was 1998, the height of Classic Trance culture." - Reza


Keep in mind. It's during this era names like Twilo NYC & GateCrasher UK were household names and considered by clubbers as near holy ground.


The JX was made for dance. It was made for parties. Underground parties for underground people.

I learned everything off this keyboard. Years after losing my 1st JX, I found one of the few still working in USA. All the harder to come by, this is my favorite set of keys.
