Dear Mr Echo

Thanks Al I don't have a multimeter but I dare say there will be someone I know who has one - I'll check it out. cheers

Hi A while ago my aging and delapidated Yamaha BB300 stopped making a noise and on internal inspection it turned out that the plastic block on the jack input has disintegrated and broken apart. Anyway a few days ago I got a replacement jack socket and fitted it (I think) correctly and it was working fine for a while. The first time I noticed that it wasn't working was after I put it down for a moment 'near' my computer, still plugged in. I had to disconnect my printer from the computer and when I removed the printer's USB cable the guitar started to make a loudish hum through the amp - I put it back in again and it stopped. The only sound I get out of the guitar now is a dull hum that gets a little quieter when I touch the strings. I've taken out the new jack and soldered it back in making sure there are no stray wires shorting anything but still nothing. Can anyone shed any light on what the problem could be (even if it is my stupidity). cheers Andrew

Strings arrived this morning thank you... however my bass died yesterday *sniff*. A pleasure to deal with. cheers Andrew
