Delay Project

[msurdin]

Hi,

I want to build a delay unit. Analog..
I love that swelling delay of Pink FLoyd/ David Gilmour. I know he used the MXR rack Delay and Binson Echorec for awile.
Is there any project that could be modded somewhat to get a good swell and tape saturation? Is there anything else a good delay from the 70's did?



Thanks a lot

Matt

rebote 2.5!! 

[msurdin]

Rebot 2.5 does that?
And links you can send me to?

Anything else out there?
I'm not looking to do anything too hard, but something fun. I was looking at the pt80, but i didnt think that had what I wanted..

its all a matter of how loud you set the effect, to get the sound Gilmour likes...

tonepad.com

its got the massive treble roll off thing youre probably looking for. the pt80 is DEFINITELY worth lookin at, but not as "analog" as a digital delay like the rebote 2.5...(yes, its digital, and yes, it sounds fantastic.)

Here's the link for the Rebote 2.5. http://www.tonepad.com/project.asp?id=51

Here is another analog delay to check out http://www.generalguitargadgets.com/index.php?option=com_content&task=view&id=48&Itemid=26

Is there any swell control I could build onto the pt80 or ad3208. Would a tape sim be easy to build onto this.

I really want that mxr rack delay sound... does anyone know about that system?

Thanks

Matt

tape delays have a swell function?

whats swell? like slow gear?

[msurdin]

Maybe its the same as feadback....getting those "swells"

[Barcode80]

i have one of the mxr rack delays. yuck. build a rebote, you won't regret it.

[msurdin]

Robots are pretty close to the mxr delay?
Does it get good swells? Or have a swell/ feedback control?

[soundcollage]

mmmmm, robots.

I have one of those MXR rack delays too, and I kinda like it, particularly for some of the "tricks" it can do, even though the tone and delay range can be easily copied for peanuts these days.  The thing with the unit is that when you switch delay ranges you also switch lowpass filtering.  the Rebote is digital also, and it is hard to imagine that the A/D conversion on the Princeton chips is not better than it was in 1981 or whenever.  Certainly we're not talking about the difference between 16-bit conversion in the MXR and 8-bit in the Princeton PT239x series.

Having said that, I'm not sure what delay range we are talking about.  A stock (single memory card) MXR rack unit provides up to 320msec delay.  Additional memory cards are needed to go beyond that (1280msec maximum).  The PT2399 chip on the Rebote provides around the same basic delay range as a stock MXR.  If you need more delay time than that (i.e., if what you are trying to mimic in Gilmour's sound involves longer delay times), then perhaps you need to look at the PT2395 chip, which will deliver up to 800ms with the appropriate DRAM chip.

Finally, the PT-80 project from Scott Swartz (available on/at GGG) is a more full-featured delay than the Rebote, and includes companding and more filtering (I think).
