I recently took a Jazz neck and put it in my SG in the neck position. Custom SH5 in the bridge. Love the bridge, but the Jazz seems to be getting way more breakup than I was expecting from a lower output pickup. I feel like the mids are too much. I've looked at the specs and it appears the SH-1n might be more what I'm looking for, smoother cleans and possibly more headroom. Raising and lowering the Jazz hasn't helped either. So, with that in mind, how do you guys feel about the 59' neck in an SG? And how many have tried a different magnet in a Jazz neck on on SG? Let me know!
