internet saying that p90 pickups make huge hum noise, is stockholom hum canceling equipped?
The only way it is hum-cancelling is if you ordered the RWRP option on the neck pickup in a set and you play with both pickups on. As soon as you turn one of the pickups off you have hum.
I have a Stockholm in an SG Junior. I have hum, I've tried to minimize it using shielding paint, a Boss NS-2 (in the front end), and an ISP Decimator G-String II (in the loop), but there's still some there depending on lighting in the room etc.
What can I say, I guess I just let my nuts hang when it comes to hum, but then again hum is really only an issue when I am not playing and I use my hands to mute and turn body position a bit when it hums to put my body between my guitar and my amp. Then again I play hardcore punk so a bit of noise is not a big issue, and YMMV.
The Stockholm/SG Junior combo is great for what I play.
