Biasing Son of Ben preamp

[cooder]

So I just populated the Son of Ben / Benson preamp board and it seems to work fine, just wondering about the recommended bias settings of trimmers.
On schematic it says "adjust Trim 1 to 2K" while the other trimmers are given with drain volatges measured at transistor. The later makes more sense to me, why not giving a target drain voltage for Trim 1 as well...? And if it should be 2 k, why a trimmer and not a fixed resistor?
A bit baffled, what am I missing here?

Trimpot Adjustment - Son of Ben

The build doc says Is there a way to test trim 1 without removing is from the enclosure? For Q2&3, is it the same as when biasing a fuzz face? One probe to ground and the other on the drain? Thanks! *Edit for future forum searchers* "son of ben" isn't searchable because the words are too...
