To achieve a tone similar to Synyster Gates' A7X sound, you may want to start with the following settings:
Green channel:

• Bass: 5-7
• Mid: 2-4
• Treble: 5-7
• Presence: 5-7
• Gain: 7-8

Red channel:

• Bass: 3-5
• Mid: 3-5
• Treble: 5-7
• Presence: 5-7
• Gain: 8-10

When using the Boss MT-2 pedal, set the tone control to around 12 o'clock and the level to taste. This should give you a good starting point for a heavy metal tone.
It's important to note that these settings are just a starting point, and you may need to tweak them to suit your own personal taste, playing style and the room you're playing in.
Keep in mind that the MX112 cab will also affect the sound,so you may need to play with the eq settings on the head and the pedal to achieve the sound you are looking for.
Also, keep in mind that the sound of the DSL15H head with the MX112 cab will be different than the sound that Synyster Gates gets with his rig. However, the settings above should help you achieve a similar overall tone.

To verify, often the voltage is stamped on the back of the keyboard, near the power jack. Should say 9V

Request manual directly from casiotone

I have a 465 sound Tone Bank Casio piano that was dropped and now it doesn't work. I'm not sure what the problem is.

Here is a link to the manual:http://www.scribd.com/doc/38337257/Casio-Mt-220-Manual

I would inspect the unit for corrosion on battery terminals AND the power connector. The connector has a switch when a cord is plugged in, and if this switch doesn't work (they get bent) the unit will not work on batteries.
Best source of power adapters is often your local thrift store.
MATCH the voltage and whether it is AC or DC required AND the polarity if the pin is + or -.
Get one with enough current.

I went there as well casio.com/usa I would try the MA 150 many times the instructions are very close to each model. If this still wont help, try Ebay and Yahoo there a lot of manual collectors there . You may even get lucky on YouTube good luck DFD please rate me
