Last week I bought a second hand Panasonic AG-7500 SVHS Hi-Fi Video Cassette Recorder. It is a professional machine with many video and audio options. I feared it would be a huge quest to find a manual. I was delighted when I found owner-manuals.com. After payment I received the file to download the next day already. The quality is great. I am very happy. Thanks!
The owner's manual/operating instructions that I purchased was the original factory document and it was in at least three and maybe more languages. I no longer have it because I sold the tape recorder and included the owner's manual/operating instructions and a service/repair manual that I bought on ebay for the new owner.
Turns out this was not the manual i was looking for. The concertmate 670 keyboard i have is a "Realistic" model made for Radio Shack and none of the diagrams on the owners manual i received matches up. HOWEVER, I must say the service Owners Manual provides was fast and efficient by being available online. The manual was in good readable condition and easily downloaded.

Creating �Custom� Wah Effects (Customize Mode) 7. With the TYPE knob, select the wah type on which you want to base your custom effect. * Until the TYPE knob is turned, the last wah type set to CUSTOM remains selected. TYPE knob CUSTOM (factory setting) ADVANCED BASS MIX CBY-WAH VO-WAH MO-WAH VOICE UNI-V Base wah type DOUBLE RESONANCE (p. 24) ADVANCED BASS MIX CBY-WAH VO-WAH MO-WAH * When selecting DOUBLE RESONANCE, first turn the TYPE knob to a setting other than CUSTOM, then select CUSTOM again. 8. Adjust the Q with the WAH RANGE knob. Q produces changes in the wah filter. The frequency range gets narrower as the knob is turned to the right (clockwise), creating a sharper filter with a tone with strong characteristics. Turning the knob to the left widens the frequency range, creating a less severe filter effect. When the knob is at the center position, the tone is as modeled. 9. Adjust the presence with the DRIVE knob (p. 25). The high-frequency components are attenuated more as the knob is turned to the left. There is no attenuation of the high frequencies when the knob is turned completely to the right.
