Thanks for the feed back guys. I'm happy to leave the LP as a rock pig for now. If I end up finding the pick ups too hot I believe there are options to tame them (volume on the guitar, possibly even lowering the pick up?). I fully intend on having the hollow body dedicated for jazz playing. I guess I'm just looking to justify kit gas in building a back up guitar that could sub in for either. The semi hollow path does seem like the most sensible option here, but I'm having a hard time looking past the PBG-2. It keeps calling to me and begging me to buy it. It won't let up.
I could have sworn you lot would be terribly biased and recommend a Pit Bull kit for the hollow body over the other options, so I'm surprised no one has. I know it would be quicker and easier to buy a completed one, but in terms of bang for your buck, would you get a better quality guitar buying a mid-range complete guitar or getting a cheap kit and giving it a heap of upgrades?
I would definitely put flat wound strings on the archtop. As for the sub guitar, I'm not so sure. I guess its possible to dial up a decent/usable jazz tone with regular strings, but flat wounds would just about kill the rock/metal sound. This is all based on assumption though. Has anyone actually attempted to use the wrong strings for the job and successfully compensated with the rest of their gear?
Should I be worried about feedback with a PAF style neck pick up? I've heard they're all unpotted.
Oh and Simon, I'm spoiled for choice in Brisbane. The thing is I trust you lot more than I trust a music sales man and would like to have a good idea of what I'm after before I step in the store.
