My last set of organ pedals and bench weighed more than my keyboard, stand, stool AND PA system I use now! And that doesn't include the massive organ and Leslie and heavy PA I used back then.
I remember making a road trip to south Louisiana and barely having room for a suitcase after loading all my gear into my full-size 76 Chevy van.
As I recall, that $20,000 organ had maybe a dozen styles.
Not just keyboards but also organs have come a long way since then
Just look at the Wersi OAX1, almost as portable as a keyboard these days
Actually this might be the time for many to move back to dual manuall organs..
Wersi or Bohm?
Or a Crumar, viscount, Nord with a Ketron SD series arranger module..
The organs are getting better and better general
Purpose styles.
