It's worth noting that Pete is talking about swamp ash rather than hard ash. From what I've heard, and from speaking to Doug at Blackmachine, they are two very different woods. Apparently swamp ash is quite middy and fat sounding, as well as being very clear.
I agree with Nolly, I have a Custom Strat with a Swamp Ash body and a Maple/Maple neck - not nearly as bright as I was expecting, sustains for days and has a nice fat sound, especially considering its loaded with single coils.
oh yeah, completely different things. but then swamp ash and swamp ash can be completely different as well... swamp ash is a label that suddenly increases the price of ash astronomically and there is no set method of grading it. Is it swamp ash because its grown in a swamp or is it swamp ash because its light!!! .... or is it really being sold as swamp ash because the person selling it knows they can charge a hell of a lot more for it if they add swamp to the start
generally with all reputable wood suppliers it comes down to weight. swamp ash is lighter because its grown in a wet area so the tree contains more water. when the wood is dry it has more air space that regular ash. This is why it can have huge pores and be a pain to finish and also dents easily. I have had some swamp ash that was as light as balsa but it can be a lot heavier and still be called swamp ash. Tonally it is a lot warmer than the baseball bat ash, but then i made a guitar out of that and it wasnt unpleasant... certainly quite a bright guitar and i had to make it thinner to get the weight to normal, but nice in its own way.
so basically ash varies from incredibly light to quite heavy. 10-15 years ago it was all just called ash and most places selling wood didnt want the stuff that went on to become 'swamp' ash because they thought it was a PITA.. dents easier and harder to finish are not the best qualities in a wood. then some bright spark used this cheap disposable wood for a guitar, some marketing mojo happened and we all want it
good swamp ash is truly excellent despite the extra problems in workability.. trust the luthier to get you a good bit
