this is a great delay and that is a great price. I've actually bought and sold this delay several times. The size is kind of off-putting, so I sell and replace with a mini delay that doesn't sound as good, so I buy it again.
I love the idea of an insert on delay pedal, to get an effect on just the repeats only. Putting an envelope filter in the insert of a delay pedal gives some really cool and useful rhythm textures and the envelopes fold over themselves.
I’ll probably pick up that pedal... even though I already have four delay pedals.
As I said, I've had this off and on for a number of years. Have it as my delay now, and will not sell again. Yet I've never stuck anything in the insert, oddly enough. Maybe I'll give that a go sometime. It really does do a lovely any kind of delay you need: slap to ambient. And with the two footswitches and "rubberneck" feature, you have the ability to get weird sounds like you would with turning the knobs of a delay while engaged, but with the ease of pushing the buttons instead.
