A comprehensive Operating and Service Manual. All schematics are complete and easy to read. The PCB drawings and complete parts list are very helpful. I would definitely recommend this manual.
Genuine Toshiba owner's manual. Couldn't really ask for more. And written in understandable English in contrast to a few recent experiences I have had with manuals for other equipment other than Toshiba but made in China and written in "Chinglish"!

10. Indicator LED This LED indicates when the effect is turned on. If the LED becomes dim or does not light when the cables are connected, the battery needs to be replaced. 11. Out 2 (Effect) Jack Connect this output to a second amplifier or to a mixer channel for effect signal only. When Out 2 is connected, only effect signal is present when the Bass Synth Wah is turned on. Out 2 is muted when the Bass Synth Wah is bypassed.
