Apologies for taking so long to continue the thread I started.
To see what's going on, I recorded myself playing with the POG2 octave down effect, and looked at the results in Audicity.
This was the setup: Fender active Jazz to a Boss TU-2 as signal splitter. One signal went directly to one input of a Zoom H4N recorder. The other signal went to the POG2 then to the other channel of the recorder.
The POG2 was set for -1 octave only, i.e.,
Dry output: 0
-2 octave: 0
-1 octave: max
+1 octave: 0
+2 octave: 0
Dry FX: off (unlit)
Q: off (unlit) Attack: 0
LP filter: 0
I recorded myself playing on the open G string, fingerpicking. Then I imported the recording into Audacity as a single stereo track, normalized the volume of each channel to -1 db, and shifted the time with the channels synched
so the first peak of the first G was at 0.1 seconds.
Here's the result:
The top track is the bass, with the direct G as the top channel and the octave down as the bottom channel. The second track is just labels, showing the time from the first peak of the direct G to various points in the octave down G. The time scale at the top is in seconds.
The image shows the octave down fading in after the direct G. The lower octave seems to be lagging the direct G by roughly 0.03 seconds, or 30 milliseconds. That's like standing thirty feet from your amp. The lag was noticeable to me, especially if I played fast repeated notes.
I tried the same thing with the octave up, and found that it lagged the direct input by roughly 40 ms. Again, noticeable to me.
And I tried the POG2 dry output. The lag there was about 3 ms. That's not noticeable to me when playing.
