    I am interested in the control layout of the G&L L2000, ASAT and L2500.

    which is the function of each knob and mini toggle both in active and passive mode?

    is the complicate layout and preamp reliable?

    About the neck i am interested in the biCut technology. is this proved as a reliable technology for cutting necks? is this a "new" tech or is this from the start of the G&L?

    thanks for helping!!

    All controls work in both active & passive mode:

    3 toggles from closest to neck to bridge (functions listed from closest to neck position to closest to bridge position):

    - pickup selector (neck only/both/bridge only)
    - series/parallel selector
    - active+treble boost/active/passive

    3 knobs from closest to neck to bridge:

    - volume
    - treble cut
    - bass cut

    I'm doing this from memory and can't remember if my order on the bass/treble cut knobs is right (but that's easy to make sure of with one in hand).

    Series mode has massive amounts of bass - parallel is more even high-to-low and has more clarity. Passive is more "vintage" while active has more bite (I never use active+treble boost).

    The pickups are voiced with extra bass and treble so passive cut-only eq is all that is needed (it's nice to have the eq in passive mode).

    The bi-cut neck is one of Leo's ideas. It wasn't present at the very start of G&L (the earliest G&Ls have one-piece necks with skunk stripes) but has been there for a while. I don't know if time has proven it as an improvement over one piece necks or not. A lot of it comes down to preference I think - Roger Sadowsky uses 1 piece unreinforced (with graphite - they have truss rods of course) necks, Laklands have graphite reinforcement, other luthiers laminate their necks out of different numbers of pieces and they all produce great instruments.

    I know that the G&L website says that they invented it, but Peavey was doing that on their T-40's back in 79. They cut the truss rod channel in 2 pieces of wood, stuck the rod in there and glued the 2 pieces together to form 1 neck. They called it a Bi-laminated neck.

    Peavey has a US patent for it. They glued the pieces back together with the grains in different directions, to guard against warping.
