Ex-Factor. Factor has tuners in the headstock and no extension.

If you want to push the fx and use dynamics to control them, then comp should be last - and the other way around.

Metcal was very similar. They even provided silicone flaps that you could change tips while hot.

Bridge needed just some filing, and nut was made by Status. E (.95) and B (.120) are interchangable without issues. No buzzing or any other unwanted moving.

I have my Status MM4 neck that Rob built to BEAD tuning. I use it now with EADG tuning and obviously thinner strings. Works like a dream. No need to modify anything.

Lovely! Wonderful!

Don't worry @Sean, I fixed my bass teacher's 5-string Tobias (yes, the original, and when it was brand new). There were issues with sound, and the electronics most likely worked by accident. After just a couple of minutes (*) of fixing the preamp, wires, contacts etc., I was confident that it would work for years to come, as it did. *) When something takes at least 3 hours, I've heard Australians say: "Just a couple of minutes."

Your choices are chinese crap and those mentioned earlier. It may be so that Weller et al. produce their stuff in China (bad) but at least their QC should be better than those no name chinooks. I know, they are able to make quality products, too.

A teacher, maybe?

I had a Sessionette with a 15" element, but boy when I connected the amp to a Marshall 4x12" slanted guitar cab! That was bass! (We didn't play very loudly. TE was way too expensive.) The next (or the next) amp was a Peavey Databass (15", 450 W), but as it was much louder, it was also very heavy and cumbersome to carry. I liked that Sessionette: never had any issue with it.

If you want to drill some more holes, that German T-shop sells both Göldö and ABM single bridges. You need to check if their width enables the spacing you are after.

The plate can be easily drilled...
