yeah, I have a old lathe, and know how to use it
unfortunately no power connection, yet

even a small sanding machine would be great
which I also have, but again, no power for it

also a bench drill would be a great help
that I have too, but no power ...

so, like I said in post #675, right now it is as much about finding a method that goes without advanced tools
but thanks anyway

I'm currently working up a 2RU integrated bass head. Bought one of the ICE 500ASP modules for sale here, which already sounds great with my existing DIY preamps.

link says it's already been saved
but I got tired of effects
I run clean passive into my DIY jfet preamp

though I still find them interesting, for study, thanks

also bought a ON-ON DPDT switch
want to try it on my passive P-Bass
to explore how it plays when having series-parallel switch option
(more on that later)
