Very nice projects. I'm following.

Here's Thomann reference for bass tuners : https://www.thomann.de/gb/goeldo_distance_ring_wksrb.htm

Looks like the headgears day.

I always read everything. This is exactly where a master volume is placed and you already have one... This trick is used on amps without a master volume to be able to use them at manageable volumes. On old tubes (valves) amps, it is very usual to add this master volume for this exact purpose. Don't forget that if it's badly made, you'll get a lot more noise too. And I would add that the Orange Bass Terror is badly designed if the master volume is useless at low to very low volume as it's really what it's intended for.

This is called a master volume...

I hope you have a week or two to listen to all these useless sounds the Source Audio C4 can do. Want an octaver ? Boss OC-5. Period.

Plywood is not light at all !

Simply more wood. It's a known fact by luthiers, never compare the exact same 4, 5 or 6 strings bass. The 4 strings bass will always sound thinner and less consistent.

This is the phantom coil for the hum-cancelling system.

Now I need to put all the details for all these basses...
