Now that Ive had more time to tweak the warlock to sound closer to the eagle I can give better comparrison. Of course itd be better if I was comparing two basses by fodera, vigier, skold, or other such where diff was just body wood.
But anyway. To me a qaulity agathis compared to a qaulity mahogany, body differs mainly in a little more treble content and perhaps just a tad more midrange. Still closer to mahogany then say alder or ash. The other diff I notice is more detail with the mahogany body bass. With a little bit harder sound to the agathis body one. This latter is like the difference between Audioquest roket 44 speaker cable compared to analysis plus oval 12. Both of which Ive owned and very much enjoyed. Though I used the analysis plus oval 12 as a small upgrade from the latter. To get more detail in the low bass and a slightly richer detailed sound overall. Oddly the better cable to my ears is also lower priced for same length pairs with banana plugs. I cant say the audioquest isnt as good overall, its even a better choice for some then the analysis plus. Those more into classical or pop music for example would prob prefer the audioquest while metal heads & electronica fans etc would more go for the analysis plus imo.
An agathis body body so long as it is a premium or othewise still high qaulity peice of agathis. Can be excellent. The same can be said for basswood, royal paulownia wood. These 3 woods however are imo less forgiving when its lower qaulity peice. Whereas with mahogany one doesnt need to be quite as picky in picking a peice for a bass body. I'll gladly pick agathis over maple, alder, or ash body for personal tone preferance. Cause I mainly orient to dark voice char.
I do agree with XtheDeadPawn in that agathis has a bold sound. Another way of say harder sound I think.
