Interesting, thanks. I wonder how much a Mosrite bridge and tailpiece would effect the tone? Also, what's the scale length on your Conrad?
About Mosrite bridge, I have an impression that it eats some of the sustain, which contributes to that "boingy" short attack character, a bit like banjo. So if you want to make a jazzmaster sound closer to Mosrite, it would probably make sense to change not only pickups, but also a bridge to Mosritish roller type.
