Nope i only play guitars and cut the wood i dont know tonal difference, hence why im asking. But i thank you for giving me a real and useful answer not just " play your guitar! ' lol i already do that but when buying a new guitar by parts id like to have a general idea of what ot go after, so sorry if im being annoying , im not trying to be im just very curious. So i think i get what you mean but just to clarify what do you mean but wide sound? So then would a thinline be even more airy is what you're saying? And then what would you call Ash? and what would you call Mahogany (the warmest kind, i still dont know which is, after your last post in my other topic) ?
Oh the comment about people should know, was more directed to the other people. I wouldn't be that BAM IN YOUR FACE rude. When youre just trying to better understand an instrument. Learning the fundamentals of guitar tone was the funnest year for gear. After you have a good image, youre just waiting for new "stuff" to come out XD or looking for more luthiers XD
A WIDE sound is created by lowering the mids in comparison to the highs and lows. By lowering the mids it seems to emphasize both the strength of the high end and low end. Thus created a wider difference between the high and low. From this you get a wide tone. Understanding the opposite will better allow you to further understand.
To get a FAT sound you emphasize the mids. What this appears to do (from the ear) the emphasized mids seems to lower the difference from high to low end. This lack of contrast between the extremes seems to create a more even fat tone.
I find the best setting more of a WIDE setup. The great extremes of a scooped tone(built right) has astonishing vocal properties because that huge contrast between high and low allows one to achieve a huge variety in tone.(based on physical manipulation)
Ok for the thinline. I noticed on some companies that build hollow bodies, there is a certain feedback. It made Anderson guitars almost unplayable, because of this feedback. I remember holdsworth talking about just this issue. He had away around it, thus I assume luthiers already have fixed that. (So I really dont like hollow bodies, atleast for electric guitar) Depending on your style, if its rock/hard rock and anything more aggressive I would stay away from thinline.
Ahh Ash... Ash is a gold of wood. (A good piece) You can feel a good piece of ash when you play. The resonance is wondrous and lush. The tone is very cool too. Most people think ash is bright, its really not so much. They just dont match it with good pickups. I've had a bunch, in a few ash guitars. But in the end, I had a C-pig and a C-diver in ash (two guitars) and they just blow me away. See ash naturally has a scooped tone. Thus a good pickup leaves chords wide and single notes sing. Its just miraculous :D BUT light ash is what you want if you want ash. Heavy ash is like a shiteeety version of maple. BUT DONT GET HEAVY ASH. Its just not worth it. For many reasons.
I really enjoyed what john suhr said about Mahogany. (good mahogany) It makes sense when you think about this too. (But, Im adding my own two scents here) Mahogany really isn't "warm". When compared to warm tones created at the end of the chain, (the sound you hear) a warm tone from wood would be more like Basswood. Because Basswood tends to cut lot of high frequencies. I always thought of it as a dead wood. It just seems to cut too much presence. Back to Mahogany. It has a very FAT midrange and thus seems to emphasize a more of the low end. Im not saying the actual low mids (maybe it does)(Im no luthier)
Sadly theres really no way of knowing how a guitar will sound till its all complete. :\
All you need is a general idea how it SHOULD sound. + Quality parts and it should sound awesome. :)
