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.
