analog delay that will self-oscillate, possibly with a 'hold' function

[tightbidness]

Can anyone recommend a quality analog delay that will self-oscillate. IIRC Keeley's AD-9 mod adds that function.

Also when I was a kid my brother's friend had a delay (think it was a Boss) that would hold a note when you held down the pedal. . . at least that's how I remember it. I've done a bit of reading about the early Boss delays and can't figure out which pedal it was or if I am misremembering. Do any of the new analog delays have such a function?

[Ben Harmless]

Hmm. Dunno. I was thinking of seeing if I could do that to my AD-9 though. I assume it's just shorting across the feedback pot. I'd have to take a look inside. Either way, I don't think it would be hard to do.

BTW, I misunderstood at first, so I assume others will too. Most think of "self-occilation" as what happens when you turn the feedback and level knobs up enough for the pedal to take off by itself. Most good delays can do that. You're referring to a switch that instantly causes this, right?

I think you may be talking about the Boss Feedbacker:

DD2 or 3 had a hold function (possibly both).

[manfesto]

The DD3 has hold (dunno about the DD2), but it's an infinite delay.

I've never tried the Feedbacker, but from the demo videos I've seen, it's more like infinite sustain instead of infinite delay - no stuttering.

Also, FWIW, the DD3 self-oscillates, and you can do the whole "twist the delay knob to pitch shift" trick, even in "hold" mode (heck, that's why I bought it). It's not analog, but it sounds great and is pretty cheap.

Hmm. Tried jumpering between the wiper and the output of the repeat pot, but it only seems to go into infinite repeat when the repeat knob is already set to something above 10:00. I tried pulling the ground, and it works at any setting then, but you can only dial in a minimum of 4 or 5 repeats at that point.

Anyone have a Keeley modded pedal? Do the infinite repeats work in any setting?

I could see easily doing it with a DPST switch, but the main switch of the pedal that Keeley uses is SPST

Malekko E 300B or 600B will do it for you, via a exp. pedal though.

I'm interested in self-oscillation however I can get it :) The switch on the Keeley is cool but twisting knobs is too. My current delay is the First Act, and I cannot get it to take off by itself using the level and delay knobs.

The Memory Lane 2 is insane!

Thanks for all the suggestions everyone. Manfesto, I think you may be right. . . I may be mixing two pedals in my memory. The Distortion Feedbacker is closer to how I remember the pedal looking, and it was still in production around that time.

I'm sure that the Boss re-201 digital pedal has a setting that you can stomp for that dub style feedback echo, you can even control the repeats with an external foot pedal and do it manually.

It's not analog, but the DD-7 will self-oscillate. Set the level and feedback knobs full clockwise and it becomes a runaway train. Twisting the delay knob is optional, but makes it even weirder.
