Excellent suggestion to continue the build! I was worried I was out of options lol. I'll try it and it does make some sense. The increase in sustain from all of this is quite amazing.
Forgot to add - I did notice a jump in volume from the Callaham stuff and adjusted my pickups down a little. I ordered the Raw Vintage and there are a lot of posts around where people report changing the tone with them.
Strings could be a biggie too. I really like the nickel ones and I'll bet the Thomatic Insfeld would do well with this setup. When I tried their sliders on another guitar they were too woody, but I'll bet they would sound great with a brighter set up.
So when I'm done, do I actually have to play this thing?
