Did you see this additional mod for the upper octave?
http://www.madbeanpedals.com/forum/index.php?topic=7497.0

On the delay--how much of a delay are we talking (roughly) in milliseconds? As much as a slapback type sound, or more?

No, only now I saw the additional Mod. I'll try it.

I'd like to report the experience with the mod for the upper octave. The change of D1-D2 to 1N34, in fact, was great. I noticed that there is, now, a little more gain. What do you think about change the OCTUP potenciometer from 100kB to 250Kb? I didn't test back the original values of C10 and C12 yet.

The delay time (in milliseconds!) I can't tell you exactly. Is about a quarter of a second (250 ms) in average (as more bass the note - like an open E, for example, as bigger is the gap...). It happens more frequently in basses notes. Almost never in middle or high notes.

Thanks

Dear friends. Firstly, I regret because I don't speak (or write) English very well ... 
I've built a  LowRider. It works very well, but has 2 problems (not too big, but are problems, at least for me...). The OCT-UP is not very perceptible, and the 2-OCT-DOWN presents a slight delay in the bass notes (like the octave-note sounds a little bit before the original-note).  They do not sound together. 
About the octave-up, the best I got was a fuzz. I tried the MOD, but it didn't work.  Also I tried to regulate by trimpot, but nothing changes so much. In the end I preferred to leave the C10 and C12 off and leave the fuzz in peace.
About the substitutions done, all of them were according to the instructions. I used 2N5458 transistors instead of the original 2SK30 (I used sockets, so I could test many other transistors, but really the best result was 5458 – I didn't find the 5457 in Rio de Janeiro). As I also didn't find the CD4013BCN, I used CD4013. The capacitors were ceramics (lowers values), polyester (little blues boxes) and electrolytic for higher values, when marked in the layout.  For the three 1uF caps without polarity I used  electrolytic NP (is it a problem?)
The steps that I've taken to try to resolve were double check the components values, wiring, soldering, footswitch and jacks wiring, orientation of components, ICs and potentiometers substitution by others of same values. How it was unsuccessful,  I decide ask in this forum about others experiences.
Are these typical characteristics for the Low Rider or I did some mistake?

Dear friends. Firstly, I regret because I don't speak (or write) English very well ... 
I also built LowRider. I bought 2 PGBs and happened the following:
1-in the first assembly, OCTDOWN1  and OCTDOWN2 presented a type of "delay" in the bass notes. I'd  taken very good octaves down, even in the high notes. Only the "delay" was the problem. The delay occurs like this: first sounds the tone one/two octave down, and then the original note, with a slight delay. On the octave-up, also the best I got was a fuzz. I tried the MOD, but it didn't work. In the end I preferred to leave the C10 and C12 off  and leave the fuzz in peace. I used CD4013 (no BCN) and 2N5458 transistors instead of the original 2SK30.   

2-in the second assembly, using the same components (I bought them all together), I didn't get the same result.  The octaves-down  no sound as well; I only hear a "hum" about stuffy notes.   I used the MOD ... and got the same fuzz ... I used the simple CD4013 (no BCN) and original 2SK30. In both of mounts I first tested the project before put in the enclosures. Nothing has changed. It was the same way, inside or outside of the boxes.
What's wrong?

I built my Low Rider without difficulties. I used the octave UP mod. Except this, I kept everything as stock. I used sockets for ICs, transistors and C10/C12. The trim pot  is mult-turn (but has no effect in the adjustment). The result was very good, except for one problem, I can't understand the reason: when I use 2 OCT DOWN the octave comes out with a little delay. Only happens in this case. The other functions are perfect. Can anyone suggest me some way to try to fix? Sorry if there are any errors in the text, I speak Portuguese and my English is only reasonable.
Thanks.
