Re: 59/C Hybrid made using 59n(SH1N) coil?
i've made a lot of hybrids using lots of different combinations of coils. So, yes I've "tried it".
Keep in mind that "bad" is a relative term. What you're asking about may sound HORRIBLY bad to one person, but may be the prefect tone you're looking for.
That in mind...I'd say no it doesn't sound bad. In fact it sounds pretty good, Does it sound thinner? Yes, a little. Thinner and more scooped (less mids). My preference is to use the screw coil from a 59 bridge pup and the slug coil from a Custom and split to the slug coil.
You might even want to try different magnets. The hybrid takes to different magnets like a duck takes to water. For a bright, clean, airy sound I like A5. For a smoother, rounder sound I like A2. For a bigger sound, especially for use in the bridge, I like it with an A8.
In any case, the hybrid (however you choose to put it together) is a great pup.
