I think I have just about all of the tools I need for setup. I need to get the 18 inch precision straight edge and the feeler gauge that Carl mentions in his vids.
Any body have a suggested list of essential tools, or your favorites?
I set up all of my basses, and a lot of guitars and basses of local pros in Vienna.
If I have to do a basic setup, there are really only a handful of tools I need, and most have been covered here.
1. Set of hex/allen keys
2. Chinese-made mini screw driver set with ratchet function, and 18 bits or so.
3. Wire cutters/pliers
3. A very good tuner for intonation (I use a Korg GT120)
4. Digital Caliper
That's for the basics, without cleaning/oiling/polishing supplies, soldering etc.
The digital caliper is my breakthrough tool of the last 2 years.
I found a standardized distance from string to last fret that gets me right in the ballpark of a perfect setup, accounting for radius and string thickness.
For example, I measure the E string, it will be a certain width in millimeter. Then I zero the caliper, and set the new distance to 1.22mm. No matter the thickness of the string, I will always have a set distance under it when I measure from the top of the string to the top of the fretwire.
I use the same method for getting a rough pickup height, and I fine tune.
I've charted these distances for reference, and then I adjust bass by bass, since not all frets are perfect, and certain string types benefit from higher or lower action.
I adjust the neck relief to be almost flat, using the first fret last fret method, then loosen or tighten until the string resonates just right, towards the end of the setup. There is a sweet spot where you can hear that a certain type of action is right for that specific instrument.
