Thanks :)

Found it in the 2008 pdf catalogue. Original pick-ups would have been an ESP LH-301 bridge and neck set with a push/pull switch for coil taps on the tone control.

So we know that both pups have been swapped out. Lets investigate further to see how much the wiring has been changed.

Is the tone control still a push/pull switch? And if it is a switched pot, does it still work?

It's a 3-way lever switch like this:

That's the pick-up selector. We aren't interested in that, we are interested in the tone control.

There are potentiometers which are used for volume and tone controls. Some of these also include a switch that is operated by pulling the pot knob up and pushing it down.

Check your tone control and see if it has a switch operated by pulling the knob up.

Oh, that's embarrassing.

Yes there is one volume knob and one tone knob. The tone knob does pull out but doing so doesn't seem to have any noticeable effect.

EDIT: I lied, there is a difference in amp noise depending on the pickup selector switch and whether the pot knob is pulled out or pushed down. Although on the settings with less amp noise, there is a weird "chattering" sound coming from my speaker that sounds like morse code. I think it still happens with the noisier selections as well but maybe it's just covered up more by the noise to the point where you can't really hear it. Any idea what that is? Lol

OK, so when the pick-ups were changed the wiring was changed to remove the coil tap as well.

We now know that the guitar wiring has been changed and that both pick-ups have been replaced by a previous owner. And the problems you are experiencing suggest that this was a DIY job rather than by a reputable guitar tech. So there could well be other issues with the wiring.

Swapping pick-ups is relatively straightforward when you know what you are doing. But there are a number of potential pitfalls that can catch you out if you don't. There are no common standards for pick-up wire colours, and there are several different ways to wire humbucking pick-ups.

You need your guitar wiring and pick-ups looked at by someone who knows what they're doing. Because of all the possible variations in how your replacement pick-ups are wound, they need to be identified properly. If you are lucky, they will be labelled, but they need to be removed to find those labels. If they aren't labelled you may not be able to work out for yourself how they should be connected.

Find a reputable guitar tech near you to check and fix the guitar wiring. And if you let us know where you are based (Country and region/city) someone here may be able to point you in the right direction.

You're welcome :thumbup:

The ESP LTD's are generally good guitars, let's hope you get yours up and running soon :)

My eyes pricked up when I read "high gain metal music", guitars always pick up noise at high gain, it's simply the nature of the beast, so the solution might be something as simple as buying a longer lead and sitting further from the computer or taking your mobile out of your jeans pocket (the reference to the 'morse code' type noise suggests a mobile polling the nearest mast). Beyond that Zen and Wonky have to covered but it's always worth trying the simple stuff first.

I did try a virtual noise gate pedal that was part of the Waves amp plugin, but I wasn't crazy about it. It did a good job of reducing the noise when I wasn't playing, but I felt like I could still hear it when playing, especially when you let a note ring and as it starts to fade away, you start to hear that amp noise come back.[/quote]

I always found pedal noise gates to be more effective, ISP Decimator is good can always try and then return it if it doesn't work out.
