I would try several other brands, keeping an open mind. I had a Charvel 625C for the last ten years, sounded really good, even with a laminated top. I also have a Conn GC size, rumored to be a red label Yamaha built for Conn. There's quite a bit of similarity structure-wise. If you're set on a...
That looks like how I get most of my electrics. Some Collegiate type takes it apart to try and "mod" it, looses the parts and sell them as projects. My Washburn was like that, except it still had the FR and tuners still on it--a couple hours rummaging through the parts boxes had it up and running.
Definitely get some sort of speakers going, that'll make things a lot easier than dragging phones around all day. Plus a small guitar amp and a couple FX.
If you have access to thrift stores, just get a used walker and put a board across the back, probably less than $10.00 in the whole thing. Paint it if you want to.
That's pretty good for a 61 key. I got a MIDI Tech 49 key semi-weighted at the GW last year for $8.00, works fine, though it doesn't have all the bells and whistles that my Axiom 25 does.
I have a 588 I got at a yard sale for $1.00, it's got a rusty, dented windscreen, but it still works. Actually most of my mics were used or closeouts, don't think I bought any of them at an actual music store.
I had a DP-008 for a while, it was handy. But now I have an iPad mini2 with a Yamaha AG03 which is a lot more versatile. Plus you can have other synths with Inter App Audio, so you can pretty much do everything ITB, although I'd still move the songs over to my desktop mac for mix down.
One thing you could try is top loading the strings, i.e. going up and over the stop tailpiece instead of stringing it the usual way. I do this on my Hamer SBFT and the bridge seems much easier to palm mute, and not as much of the saddles are exposed.
Apple also likes pimping Apogee and IK Multimedia hardware. I did buy an iRig Pre, but that was more because RS had them on sale for $27.00 at Xmas. It works OK, but I guess not fancy enough, it seems they've discontinued it.
You sometimes have to try different combinations, I've found some things that don't sound that great live, but make a good recording. Like some of those little battery powered Marshalls, lol.
The iOS 8 upgrade is what breaks things. My iPad mini retina came with iOS 7.1, my Casio CTK 601 and UNO adapter work fine with the CCK. LogicRemote also works fine, even though iTunes says it needs iOS 8.
If you really get an itch to upgrade DAWs, Logic X has much less of a learning curve, since GB X is now basically Logic Express X. Before you do that, you might want to try MainStage, which allows you to download all the JamPacks and Logic instruments, pretty cool for $30.00, since they'll all...
