hi ive just got a 6505+ 112, i know theyre noisy things but i get a really bad buzzing

but the most annoying thing is when the volume is higher than 3 or 4, if i take my hand off the neck, there is an awful screeching sound. the high strings vibrate ever so slightly and it just goes through the amp and makes this horrid really high screeching !

btw ive got all knobs around 5-6 minus volume (pre)

how can i stop it?

What guitar are you using? Are you using a noise gate?

Get a noise gate, and check the grounds on your guitar, it sounds like it might not be properly grounded.

i just turned my guitar vol knob all the way down and the amp is hissing, is this normal?

6505 is a noisy amp, they should sell NS2s as a bundle with them, to check if your guitar is grounded, touch nothing but the metal bridge, if the hum reduces its not grounded properly, look for loose wires etc etc it may need soldering.

otherwise, maybe you have a bad tube or dodgy cable.

The answer to your problem is in the thread title. It's a 6505, it's supposed to sound buzzy and screechy.

Okay, in serious terms: it sounds to me like you may have a grounding issue, either with your guitar, amp, or wall outlet. Try a different guitar and see if it does the same thing. If it doesn't, then your guitar has a grounding issue, most likely existing in the jack. If that's not the issue, move the amp to a different electrical outlet and try it out there. If it is still making this awful noise, take it to a tech and have them have a look.

Check cable. Use different guitars. Otherwise Pre-amp tube maybe?

i've tried loads of different cables and its still the same. A noise gate isnt a soultion seeing as it shouldnt happen in the first place. seriously, i have the volume on 2 and gain on 4

its unplayable as when my hand stops touching the high (thin) strings you get a huuuge SCREEEEEEEECH caused by a series of vibrations

EDIT: it also happened with my old amp

i just tried that and indeed the buzzing does reduce a LOT. if i tap any metal on my guitar infact, it makes a little crackling sound.. man, i dont know what to do with it tho.. do i open the back? or what

i'd rather find someone with tech knowledge and tell me what to do online then do it myself. taking it somewhere costs time and money. it will be some stupidly easy soultion anyway.. techs just scam you these days.

Good man.

Do you own a soldering iron/ solder?

Here's what to do:

Unscrew the 2 screws on the jack plate. GENTLY pull it out, along with the jack itself. There will be 2 wires connecting to the jack: a red/white (depending on manufacturer) wire and a black wire. The colored wire is the main wire while the black is the ground. If the black wire is disconnected, then you've found the answer to your problem. Solder the black wire back in place and the issue should be fixed. If the black wire is not disconnected, then the problem probably lies in the pickups or the bridge grounding wire.

It would really help if you told us what model your guitar is.

Okay. You'll need one of those. You can get one for $15, that will come with solder that should last you a pretty long time.

Open up the back plate, and check to see if anything is disconnected.

Your ground wire is going to be bare, so it'll just look like silver wire. It should run to the back (read: bottom) of your volume pot, and go up through the guitar to connect to your bridge.
