Thanks MDV. That's what I thought you meant but wanted to clarify. I'll get on to deihm and ask if he is able to do a comparison clip so that I can get a better idea of the alnico vs ceramic.
gepetto33 - my guitar is all mahogany, except for the fret board which is rosewood.
I might get in touch with Tim and get his 2 cents worth too. If only there was a better exchange rate between the AUD and Pound, then I could get a few and try them all out haha
Just to add on too what gepetto33 said, I just put some c-bombs in a solid korina guitar with rosewood board tuned to drop c and it is VERY dark sounding & bassy. I know you said you like bassy, but in this axe it's just overboard as the high-mids & highs are just way too overpowered to cut through well. Simply not a good match IMO. I mention this because korina is in the mahogany tone ball park, just typically brighter and this axe is no exception. So that said I'd probably shy away from the c-bombs in an all mahogany guitar based on their eq too.
Even if the eq curve on the c-bombs promised to be more agreeable with your guitar, I agree with MDV in that there isn't much, if any, post-rock/post-metal going on in the c-bomb. The voicing is pretty different IMO. Compared to say a Neurosis Times of Grace type of tone, it's much smoother & modern sounding. It doesn't have that more aggressive-vintage thing you hear in many of those bands.
Not to derail the thread, but....MDV, outside of the C-bombs being tighter and smoother than the regular nailbombs, how would you compare/contrast them?
