Ok - I have a Marshall 4-12 with the Marshall silver celestions. I've put maybe 5 hours on it.

Here's the thing - on the low E, on some frets it gets a fuzzy sound. I play clean and sometine on some notes I get a slight rattle - very slight.

No big fuzziness or flapping sounds. So do I just need to play it more or does the cab have a problem?

Thanks!

4 Words for you Nigel: Bass Boat Blue Tolex

That's the answer. Cover the cab with that and the fuzz will dissapear :p

Seriously though, might be voice coil rub, not necessarily a destroyed speaker.....

Hey Steve!

Blue tolx solves everything! LOL...

I'm hoping they're OK - supposedly they are each 25 wats for a 10 watt total and I've mazed out at a 50 watt amp not even pushed throught the cab.

I'll just keep playing it and see how it works out.

Cheers

Hey Jim!

It's a bottom cab from the JTM45/100 limited series. I got it as a second locally in toronto. The speakers look like this. My cab looks identical inside.

A slight rattle on the low E, eh? Does it do it with different guitars? Try it. As for the rattle, well, it could be:

1) Cab handle
2) Caster socket/screw/caster itself
3) Loose mounting screw on a speaker
4) Something loose in the speaker (that would suck)
5) Loose panel screw
6) Something that vibrates in the room you're playing on that note (had that happen here, too)

You'll have to play detective to narrow it down, I'm afraid. Good luck.

Jim,

Thanks for the tips. I'll check it out and yes #4 would suck big time...:jo

So I opened up my cab and the speakers were not tightened up very well. I took the screwdriver to them and tightened them up a bit - not too much.

The sound improved quite a bit. There still was a touch of a rattle on certain notes but that may just mean opening it up again and tightenng the screws some more.

And Jim of Southbay Ampworks - you are the best at what you do - thanks for your advice - it really helped!

Cheers

Nigel
