The ESP Guitar Company

hello,

I have the above guitar that I am trying to restore to original condition it has esp tagged single coil pickups.

I assume they are active as there is a battery inside and they sound great...

I have checked all connections.....there is a mini preamp board inside the guitar...i have just replaced the pot with the correct value pot

could anyone give me any advice regarding what to look at as I believe these pickups are noiseless too and they are way too noisey when selected individually....when two are selected, they are quiet like a regular stratocaster.

could anyone give me details on the pickups models too

please help...and thank you in advance
