I have a Zoom 707 II which I use for practicing on my travels, trouble is the connections on both the input and output jacks are loose and the sound keeps cutting out. Any tips on how I can fix this, btw I have checked and it is the Zoom unit and not the cables / guitar / amp!
Are jack sockets secured to the front panel by nuts? If not this will be a recurring problem and it really is cheapo personified and an all to common practice these days (I even read of a poor soul with this problem on a MOTU AI and he seemed to getting little help about it) .Quote:

But I might be doing Z a disservice and there might be nuts. If so you still have to get it apart but this time tighten the nuts THEN solder/repair the PCB (would be better to remove jacks and start afresh but probably beyond noob skill?). Even so, lock the nuts with a weak glue, clear nailvarnish is excellent for this purpose (or PINK if you are that way inclined!).

I had a Zoom RT323 that I took apart last week as the left output jack only sometimes worked. Originally I had thought it was a dirty ocntact as my drum machine has taken a fair bit of use so I sprayed contact cleaner on it, which didnt work. I thought it would just be a smiple jack swap and although I didn't have a spare I figured I'd swap one of the others I don't use. Turned out the solder had litteraly cracked away from the PCB on the tip connection. This was clearly visible and although I added more solder (and remelted any dodgy looking joints while it was in bits) you could easily do this even with a fairly fat soldering iron if it is the problem and just remelt the existing solder. Worth a look with a multimeter set to continuity checker anyway if you have the tools about. It is likely if they are both doing this that something similar has happened over time.
