Well some tips:
Basswood:
Basswood is light, stiff, and stable, which makes it particularly effective for necks and bass instruments thanks to its excellent low-end response. So you will have a lot of low end kick in.
Many think that Basswood is not so good, as it is relatively cheap and many low end guitars are mode from it. Far from it, basswood is an excellent choice for a wide range of guitars and basses.
Alder:
Alder is a lightweight wood that is highly resonant, producing a full rich tone. When used for solid-body construction, alder provides a very good low end and midrange with the best performance in the lower mid range. Alder also exhibits good high-end characteristics and sustain. So an
alder body would be more allround sounding than basswood. Excellent choice of wood for Evos btw. Downside: Alder will age in its color which might show even on the guitars painting, though Ibanez uses an extremely thin furnier of another wood to protect the alder body from aging effects.
Mahagony
When used as a top, mahogany has a relatively low velocity of sound (compared to other top woods), considerable density and a low overtone content producing a solid tone, and responds best at the upper end of the dynamic range. Mahogany-topped guitars have a strong "punchy" tone that is well suited to blues playing. If combined with a Maple Top it will go more in the direction of an Alder body with a warmed up tone.
