I have some newby questions, but I just got my first PSG and I've been wondering about some of this. Reading about coepedents, one thing I notice isn't always clear, or I haven't picked up on it, is what happens when two pedals or levers affecting the same string are pressed together. On mine, which is an S10 MSA Classic from the mid 70's, if you press C and the knee levers (RKL, RKR on mine) you get something counter-intuitive to me. Holding down the P3, the E is at an F#, and I can lower than with RKR to F, but if I hold down C and press RKL, they don't interact and C stays at an F#. Is this normal? I half expected to get 1.5 whole steps up with both depressed.
Full copedent is this:
It's different from most others I see, notably no lower on the 6th string, no lower on the B strings, and it doesn't even match the copedent described in the originla manual. I'm happy to just learn this guitar how it is, but there looks to be the possibility of adding a 4th pedal (the slot is already existing), and I assume it's possible to have levers reconfigured. Is this missing anything you would consider key? If you were me, would you change anything right now, before trying to work with things as they are, or just dive in to learning and worry about adding/customizing in a few years if I run into roadblocks?
Any opinions or advice is welcome. Having a blast so far. |

What you describe is normal.
I wouldn't change anything for now.

Your C pedal pulls the E to F#. Your F lever only pulls it halfway to F#. This is normal. The changer finger has already moved past the F note, so the F lever has no effect.
The lowering lever moves the changer finger in the opposite direction, which is why it lowers pedaled F# note. the note you are hearing is probably out of tune. The fine tuning of that note is a feature we call "tunable splits" which might not be available on your mid-70s guitar.

| Ah, so that's what "tunable splits" means. I've heard that term but wasn't sure what it meant, thank you. |

Hi Weston,
Although pressing a raise pedal brings a note up and also pressing a down lever (on the same string) may subtract from the note, (as b0b brought out, a "tunable split"), using 2 raises dont "add up" to each other, to raise the string even more. "Tunable adds" hasn't been invented, yet....Pat |
