Hey Guys.
I just got a gibson explorer faded cherry (OMG FINALLY! 4laugh )
I have a problem with my bridge pickup on the clean channel of my marshall avt 150h. When I use the bridge pickup on the clean setting, the sound is all fuzzy and distorted, but when I switch to the other two positions its fine. Does anyone have any ideas or suggestions?
Thanks alot!

Sounds like the wiring isn't quite right or the pickup isn't shielded well. Does the noise get louder when you put your hand on the strings (just muting the strings, not playing or making any noise)? if so it could be that the wiring isn't grounded well, or that the "hot" wire and ground wire are reversed (it happens). you can get that fixed at a guitar shop or yourself if you know how to solder well.
If touching the strings doesn't make it louder, it could just be that there isn't enough shielding around the pickup, which means it is getting interference from outside sources (the metal plate, or tape or foil wrapped around the pickup is the shielding). My guess is that this is the problem. you can use some foil to wrap around the pickup but I would just take the guitar to the shop for this to try to get it properly done with some good materials.
Hope that helps
Oh, and congrats on the new guitar!!!

If it were a grounding issue, the buzz would go away when one touches metal on the guitar.
I'd say that the output of the pickup is distorting the amp. Try rolling down the volume pot on your guitar a bit.

Yes, humbuckers do have higher output than single coils, but that doesn't mean that every amp should be tailored to them. During my guitar lessons, if I want to play something clean, then I have to roll back the volume on my Les Paul, because at full volume the guitar distorts the amp unless I play very lightly.

thats true! I have also had to do that some times on my G&L, usually only on the neck pickup though, not the bridge. wasnt saying every amp should be fit to humbuckers though.
to the OP: I think the best way to fix the issue is to use slappy's fix and then post back if that didn't help.
btw slappy, what did you teach? now that you said les paul w/ clean channel, i'm curious.

Thanks for the help guys!
But there is one more thing I am concerned about.
When I play certain notes on the neck, there is an abnormal buzzing sound by the bridge, possible where the bridge holds the strings.
Could you guys tell me what this is? or how I can solve it if it is a big concern?
Thanks!

I'm not entirely sure what you're asking, but I take lessons at my local music store. The amp I get to use during lessons is a Fender G-DEC, on the "Funk Rhythm" setting for clean stuff.
Demonic, I'm not really sure what to tell you about the buzzing. The Tune-O-Matic stop tailpiece configuration that Gibson uses is usually really stable. I'd have that looked at.

Psh, I wish. Though if I did teach, I wouldn't have many lessons' worth of material.

Sounds like your action could be too low. Your guitar could be warped cause of the weather and what-not, so you should get it set-up wiht the string gauge you want and stuff.

yup, as absolute said your action is probably too low, just be sure to adjust and true up your guitar's harmonic intonation after you adjust your action. you can do this by adjusting the individual saddles' position on your bridge for each string. You will know when its perfect if the 12th fret harmonics are perfectly in tune with the 12th fret notes.
oh, and if the neck is warped, you can fix that by adjusting your Truss Rod. tighten the bolt behind the bell shaped plastic in the headstock to bend the head forward. loosen it to bend it backwards. I doubt this is the cause of the buzzing though, because you would hear the same buzzing near the first fret, too.
