The Korg Toneworks Pandora PX1 is as old as the hills now, so when I bought one second-hand recently, the search was on to find a manual for it. A pom who calls himself Johnny Shredfreak was kind enough to put manuals on a webpage after he was sent one from a young Aussie named Jacqui.
This webpage doesn't exist any more, so I have set up a Yahoo group with a zip file of the manual in the files section. (Yahoo Groups, PX1)
The unit is so small that when I first went to show it off to Ziggy I was unable to find it in my FX case!
If you see one hanging around in your local Cashies or where-ever, buy it but don't pay too much, there are some very nice distortions and even a nice vibrato effect. Mine is hissy, and as I usually use more treble than average on my amps this is an issue. But I haven't played with the Noise Reduction settings yet, and postings on the Net suggest it can run quietly.
I have seen posts where people tape or velcro their unit to their guitar strap, and this is definitely the way to go with the Pandora.
