Hey Cybersnyder,
I have just picked up a BOD and yeh it sounds great but the tracking across some notes on the G string is very iffy (usual suspects 4-7th fret and some higher notes) - this is across 2 different basses. These basses don't have obvious dead spots (ones a Warwick and one a Fender) but tracking does glitch. I appreciate you have to 'play' an analog octave pedal but do you have these issues with your new pedal, I know your first 2 you weren't happy with??
That's exactly what I ran into before. The first BOD I had was terrible on the G string. Up around C, D and E on the G string there was a half of a second delay between playing the note and getting an octave.
I've just come back from shop, where I tried BOD out of curiosity. I have Jazz with obvious dead spot on C# on G, and much smaller dead spot on C on G string. Well, what BOD revealed to me is that I have dead spot on H on G string as well, which I can't notice by ear (so much 'bout my ears). BUT - it didn't manifest as any sort of delay, but rather octave would start to warble during note decay, more prominent dead spot = sooner it would go to warble city. Sinca I play fast rock, only C# would be an issue - further more warble on C# is not bezerk-ish, and it only does octave jumps, so for me - not an problem but a feature. Somebody else might cringe.
OTOH (and why I'm writing this post at all) - bloody thing tracked
everything else bloody perfectly, right down to F on low E string (it only started to warble on open E). (Notoriously problematic for analog octavers) open A was perfect, G and F on E great. Kudos to MXR, they will soon get new customer.
There is of course one thing I need to mention. I play with pick, very clean and precise, with string stopping, and (of paramount importance) I play with neck p'up full on, bridge backed by 20%, and I pick from halfway between p'ups to right above neck p'up. When I soloed bridge and started to play between bridge and bridge p'up, it was warble city all over the neck. So BOD works perfectly for me (with favoured setting : all on 11), but I gues it might not work at all for somebody else.
