I have a buddy, a mixer, he said he had something to show me at his place. He acted like it was really . serious, So, I went over had lunch and what he wanted me to see was a technique for tuning a spring reverb.
He had broken open a unit extended the rca drive lines to the actual spring unit and had it set up so the could swap out the springs. Then he showed me how he would tear little pieces of paper and stuff them into the spring coils. We then sat with headphones for like an hour. And I listened as he put newspaper, a Time magazine and bits of index cards INTO the springs. Different papers had different weight, therefore different effects. Also, he found the middle and each end would make a big difference.. Other people were using different rooms, and they totally tripped out that I sat with him for so long. They had long considered the project worthless, but I was impressed.. When I say small, I mean a quarter of an inch to half an inch.
The effect seemed a little like it was an adjustment that could only go one way from zero, but should have a second direction! And with enough crap shoved in there it just became too heavy and the output dropped. COOL!
I'm really getting off on an old Eventide H949, that I think is broken, sure hope so. Anyway the Harminizor just sounds out of tune and oscilates, but the delay is cool. I am thinking about that and a spring if a reasonable mix opportunity presents itself!
