Acoustic Guitar Pickup Repair

Hey all,

I just acquired a 3rd-hand acoustic guitar - it's a Takamine EG-334BC and it sounds really good, but the pickups aren't working. It's a bridge pickup which goes into a pre-amp which is then sent to the guitar's output. The preamp got fried a couple of years ago, and my friend (the previous owner) tried to bypass the preamp and send the pickup's signal straight to the output. However, it is picking up a LOT of hum. The pickup doesn't have a ground wire - just one wire for the signal. Could this be a ground loop problem?

Is there anyway to rectify this, or should I just give up the idea of using the pickup as a passive?

P.S. I found that it was soldered in such a way the 2 connectors (hot & ground) weren't that visible, and they're actually there (which was why I was really confused earlier when I only saw one). I tried measuring the output impedance but it seems to exceed my multimeter's range of 2mOhms.

ws2003 worth it?

I am setting up a server - and if I really had a choice, I would put some variant of Linux on it - unfortunately, I don't have that option because some of the software to be used on it is windows only.
(I'll be installing stuff like apache2.2, php5, perl, openSSH (&SFTP/SCP), mysql, etc, mainly all freely available server software)

Now, I am deciding between two OS'es for the server, I have either the choice of putting WinXP Pro SP2 or Windows Server 2003 R2 Enterprise (32bit) on it (I also have access to the standard/web editions). Now, I'm not going to be using IIS, running a domain, or any real features which WS2003 provides more so than XP, so I was wondering which to install.

Are there any compatibility issues with WS2003 which differ from XP Pro? (drivers/programs)

Routing/Loopback Problems?

Not sure whether this comes here or under the network forum...

I am running a win32 server (FTP, SMTP, HTTP, POP3, HTTPS) with a Linksys WRT54G router [firmware Alchemy-V1.0 v3.37.6.8sv]. Let's say my server's internal address is 10.1.1.3, and a WAN IP of say 219.95.12.34 .

Now, on a different computer on the internal network (say 10.1.1.4), I try to access http://10.1.1.3 (or any other service) it works fine, no problem at all. http://219.95.12.34 also works without any problem.

Back on the server, I have no problems accessing things through the loopback interface (127.0.0.1) or it's internal LAN IP (10.1.1.3). The problem comes when I try to access it by its WAN IP - the connection just times out (on all services).

I think it's something to do with my router, because it I port-forward to my backup server - then now the backup server has the problem of not being able to access it by the WAN IP.

Any ideas why? (I'm still quite an amateur in this area)
