Rock’n’roll is not a crime!
I’ve been playing half of my life classic Rock without arp and transpose also. I only got a D50. So little did i know haha.
We played sweet home Alabama, jump, rocking in the free world, with or without you,…
Those days were most heavy. The fines on drinking weren’t that high so half of my life i remember big parties with indeed now and then some tension.
But I’m glad we evolved 
Technically, musically and society. 
In what city are you playing? New York?
No but serious, what kinda covers do you guys play? And also, in the 70s they used delays and arps so it’s kinda important to have them in tempo isn’t it?
