Hi All!
I recently purchased this Tempo King pedal to go with my newly acquired 1970 "Sparkling Purple Pearl" Modern Solo/New Rock Outfit... http://www.ebay.com/itm/Vintage-Slingerland-Super-Tempo-King-Bass-Kick-Drum-Pedal-/190907694712?_trksid=p2047675.l2557&ssPageName=STRK%3AMEWNX%3AIT&nma=true&si=JL4X6gs3RzT5KAl76b3VVsDwuxY%253D&orig_cvip=true&rt=nc
The Tempo King arrived and is incredible! However, I made it even better by swapping out the black nylon spring cam for a fully enclosed ball bearing cam and "S" hook from a Slingerland Yellow Jacket pedal. Picture attached. The pedal is incredibly smooth, silent and fast and one of the best pedals I've ever played, including most modern pedals!
As to my Purple kit, I'm still doing a few things to it and will take/post pictures when complete!
