Only two: a Maxon AD-80, then sold it when I got the AnalogMan ARDX-20. The AM gives me everything I want in a delay--a warm and subtle always on effect. Reading these lists, though, makes me feel like a slacker.
Boss DM-2, DM-3, DSD-2, DD-5, DD-7, RE-20
Way Huge Aqua Puss, Supa Puss
MXR Carbon Copy
Diamond Memory Lane 2
Catalinbread Echorec, Belle Epoch
Arion Analog Delay
Mooer Ana Ech, Reecho
Boss DM-2, DD-5, DD-7(2x), DD-20
Line 6 M9, M13
Visual Sound H20 V2, V3; Dual Tap
The Timeline and H2O V3 are the only ones still on my board, and the Dual Tap is still chillin' in my room... not sure what will come of it. Haven't really seen a reason to change from the Timeline as I have it hooked up to my MIDI controller, and my life on stage has never been easier...
ill try this in order of purchase
DM2 & DD2 (from a yard sale) - and i still go back to it every time
SIB Mr Echo - also got a soft spot for this one
Guyatone AD-X - on the hunt for it again
Memory Lane 1
And i still use the earliest ones on that list
DD2, DM2, DMM, Replica & Mr Echo.
I'd like an AD-X back if i can ever get one.
