Lakland JO5 LH-3

[cegrant]

I have a Lakeland JO 5 with the LH-3 preamp. Last night at church I had a terrible hum/noise. We were able to eq and gate the hum so I could use the bass.


Are the single coil hanson p/u's hum-cancelling or not., especially with both on. I want to make sure of this before I begin looking at ground loops and other causes. I used my 55-94 with no problem this morning.

I'm never heard of this issue from a JO5 but have you tried it through multiple systems?

[murphy]

the jo5 pickups are not hum cancelling
Single coil.
But should not hum with both wide open.
Sounds like you have an issue that needs addressing, though
