What is in the 2nd compartment on the back of some Alembics? It appears too large to be a battery compartment. |

4 9v? I do not get it. I though LED's consumed very little energy? Is there an separate Battery for the op-amp? |

More voltage does not equal more energy. |

When a bass has LED's there is a set of batteries for the LED's and a separate battery for the preamp. Keith |

Are you asking about Series basses? They are quite different than the other Alembics. The "normal" compartment has a lot of pots and connectors. A Series I would have 4 pots, but there are also Q-switches, the 5-pin stereo output jack, and a very complicated 1/4 jack. On the other side of the body, there's a the preamp and EQ boards. There's a tunnel between the compartments with a lot of wiring. There's also a third, smaller plate in the center block that holds a pair of 9V batteries that power the electronics when you're not using the 5-pin external power. Sometimes it's round, sometimes it's square. There was a period where Series bodies were quite thick, so the electronics were all on one side. And, as you probably already knew, the Series basses are semi-hollow contstruction - the neck/center block runs the entire length of the instrument and the top and back are 1/4" thick, but they bandsaw most of the center core out. This is only really visible when the plates are off. David Fung |

My Rogue has three compartments. One for the electronics, one 9v compartment and one for the four 9V batteries for the LEDS. I don't know if they are in series or parallel. Will work for batteries! |
