Ok so I got it today!
Tried messing around with is, for the few seconds it was on and off with intermittent signal, this preamp sounds excellent. Sounds so smooth. I really need to get this unit working.
Ok my observations so far:
The unit starts up with the error 2 message "e2". I don't really think this is the issue. Then it will kick back into life again and then jump around presets from what I can see. Other times it just has two dash marks on the display.
When it has the two dash marks as the display, there is noise, like hiss. And you can play the guitar a little bit. What I mean by that is it allows sound to get through and to some extent the controls at least for the input worked. Nothing else seems to work though.
The very first time I powered the unit on, the controls all of them seemed to function normally until the thing went haywire jumping presets before settling on the - - screen.
Things I have noted, the rear input is dead, doesn't allow signal. The ext effects 2 Left send jack doesn't allow anything to be plugged into it at all. It's jammed with something and I do not see why it will not accept a plug.
The button on the front panel for footswitch one is broken. Seems like the switch beneath its is broken and needs replace. It's like one of those switches you use to open the tray on your cd dvd drive on your pc.
This unit needs a 3v battery surprise, surprise to store the presets. I tried to replace this thinking it was a simple slide out job but know the dam thing has some kind of strange metal clip that looks almost soldered to the bottom of the 3v battery some how. May be not soldered but it's attached some how. And since I tried to wedge a screw driver on the top side between the metal clip and the batter I have f*cked it up a little bit. Still seems to hold the battery in place, not sure what the contact is like though.
Here are some pics.
