HOW TO SET UP AND USE
First, SPEAKERS. The G-1000 is NOT a high-power metal machine. If that's what you're
expecting, you're probably the guitarist from Dethklok—in which case, you're a FUCKING
CARTOON, and where did you get the money to buy this amp?? Take it back to the shop
NOW, Skwisgaar! Go sodomize William Murderface with a solid-state amp! He deserves
it!
The G-1000 was intended as a practice or recording amp......which happens to sound like it's
about to explode in your face, turkeyneck. It wants to see a
separate 8-ohm speaker load on
each channel
. (16 ohms is acceptable, 4 ohms is not recommended.) It is possible to modify a
2-driver or 4-driver cabinet for the G-1000, but it would require a technician's help.
For best results, we'd recommend a
reasonably-efficient
speaker. Most 10-inch guitar
speakers are suitable. Big, massive 4-12 cabinets with Celestions will not work as nicely,
because they are power-wasters. Most “studio monitor” type 2-way speakers are not very
efficient, and won't be loud enough. If you REALLY want more volume, either take the G-1000
back and buy one of those crappy Marshall things, or get EFFICIENT HORN-TYPE SPEAKERS.
Horn systems for PA use would be suitable. So would hi-fi horn speakers like Klipschorns.
(I don't give a rat-fuck about your endless quest for the “brown tone”. Brown is what your face
is like, after I wipe my ass on it.)
The SPEAKER outputs must NOT be plugged into a line input. THE SPEAKER OUTPUTS
MUST BE LOADED WITH A PROPER 8-OHM LOAD. DO NOT use the outputs to overdrive
another amp. Shithead. It won't get you any more distortion. The hell is already built into the
G-1000. Because you like red-hot things up your butthole.
Each channel has its own SEND-RETURN jack. It is NOT necessary to connect anything to this
jack to use the amp normally—it is provided for addition of outboard effects or for direct
recording of the preamp outputs. You MUST use a 1/4” STEREO jack here. The output of the
channel preamp goes to the TIP connection of the jack, and the input to the power amp for
that channel goes to the RING connection. DANGER: The SEND signal is hot, about +10 dBu,
and you CANNOT run it into a 600-ohm input. Nor can you run it into a guitar pedal—
it might
destroy the pedal.
Run it into a HIGH-impedance (100k ohms or more) unbalanced input
ONLY. The RETURN input to the amp can be driven from any impedance, and requires (guess
what) about +10 dBu for full power.
Speaking of power. If your amp says “120v” on the rear panel, use 120v only. Changing it to
another AC mains voltage is possible, but requires wiring changes inside the amp. Non-trivial.
You wanted a deviant amp. Well, compromises have to be made.
The INPUT jack on the front panel can accept any instrument or line level signal. Since the
G-1000's entire signal path is 100% vacuum tubes, you will be hard-pressed to damage
anything. (As if it weren't “damaged” already.) You want to worry about something? Worry
about the amp overheating. Free advice: pump cool air directly into the cabinet. It may help
prevent damage. Buy it an air-conditioner, it will love you in the morning.
