On our lead guitarist's ESP EC-1000, it is factory equipped with what appears to be EMG 81/85 combination. The wiring appears unmolested. The battery box was replaced and the battery reads 9.25VDC. Now, I know that EMG's require a 25.0Ω potentiometer - Twenty Five Ohm and not Two Hundred & Fifty. So, I decide to take readings and make sure everything is properly connected.
The guitar has a Bridge Volume, Neck Volume and a Master Tone Control. Each pot is arranged in similar fashion. Looking at the volume pots, the far right lug on both is soldered to ground. The tone pot has all three lugs unsoldered.
I took readings between the ungrounded lug on each volume pot and the center lug (wiper) and wrote them down.
Bridge Volume: 16.8Ω @ Full CCW (Yes, that right, CCW) and at Full CW the reading was zero
Neck Volume: 17.4Ω @ Full CCW (Yes, that right, CCW) and at full CW the reading was zero
Tone Pot: 24.8Ω @ full CW and at full CCW it reads zero.
Tone pot has a Ceramic disc cap soldered to wiper and ground marked '104M'
So, everything looks in order and nothing looks to have been re-soldered.
All the controls on the guitar work normally, in that when you turn the volume up, the volume goes up, etc., but the output is very low (across all there pickups) and it produces very low gain, as if the volumes are rolled off to about halfway on a guitar with passives.
Thoughts????
