It is more of a slapback, and the preset times aren't quite as fun as Page sliding the time control back and forth on his Echoplex.
The Roland Space Echo gave all these things some serious competition.
I personally have had some of the best luck with oil can delays, like this one from 1968, shipped it to someone in Germany years ago.
I'm not personally into slapback, more into spacey repeats, and that's what this one did.
This is the Tel Ray Ad-n-Echo for those who've never seen one of these before.
My last tape machine, maybe really my last tape machine. In the 80's I always had a couple Echoplexes, one to use and one for parts but eventually all the motors failed.
