I'm in the "very excited" stage so please bear with me! I have a good woodworking/mechanical background, have been hacking around playing for about 40 years, and now have a son who is actually a good guitar player. I play a '37 Gibson L-30, very old friend with lots of character but a limited guitar in terms of sound; my son has a Taylor 314ce which makes my jaw drop. I'm not very good but enjoy it and my son is inspiring me to apply myself more - which of course means I need a new guitar!! Researching things as I do I came across the new (to me) and improved internet world of guitar building, which seems very exciting - I actually built a Stewmac banjo kit a hundred years ago and it was a daunting task back then, and as a result I brushed aside the idea of building a guitar that could sound remotely normal. That has stuck with me all these years, but after looking at what's available now it seems I'd have a puncher's chance of making something good, maybe even above average, and since I love making stuff, playing a guitar I'd built would really be amazing.
So my real question is, if I build a guitar, how is it going to sound? I realize there's a lot of unknowns in that question, but to maybe put some boundaries around it, I figure I'm going to spend $1000 on a kit guitar more or less. For that money I think I can get a pretty good solid wood guitar, better if I'm buying used. I've read a lot of builder reviews raving about the sound of kit guitars, but I imagine there's a fair amount of ownership bias, which is understandable and great. I just don't want to spend a lot of time and money on something that has a 50/50 chance of sounding like a brick (like my banjo...). So reassure me!! If it matters I'm looking at the 000 body style, spruce/rosewood/mahogany, and if you can't tell I really want to do this and am trying to talk myself into it - please help if you would

Many thanks!
