PT-80 delay. Analog Dry signal?

With the PT-80, Is the original guitar signal maintained without being A/D-D/A converted?  To clarify, does a clean signal go from input to output without touching digital territory?  Obviously the signal is converted in order to produce repeats, but is the initial guitar sound untouch by digital? 

I've done a good bit of searching and come up with nothing.

Also, is there any drop in volume or loss in high end tone in the ORIGINAL signal?  My Line6 DDL-4 or whatever it is has a noticable volume drop (yes I know Keeley can mod it...specs on that anyone? ;)) and also a slight amount of high frequency loss.  I don't use the Line6 for anything really but short delays, so I was thinking about selling it to buy parts (replacing it of course with the pt-80.

Any thoughts on any of this anyone?

Thanks,
CJD

I just looked at the schem and it looks to me like there's no dry signal as such.

Of course someone may refute this.

Well I guess I'll refute myself. :icon_redface:

It looks like as you turn the delay level control down you get the feedback signal from the 1st compander stage instead of the delayed signal.

Sheesh, that had to work somehow didn't it?

I built one a while back for my multi-fx box and can tell you the volume is actually raised a bit along with slight brightening of tone. The opposite of your Line 6 it seems.

Go to GGG and look at the schematic. The dry signal goes from the output of the input preamp to the input of the output mixer (via 10K resistor). The PT80 is really an analog delay with the BBD swapped out for a PT2399. Go to GGG and read the entire article for this unit. Very enlightning. Then build one! I LOVE mine! Have fun!
