Oh, i think i know where i thought wrong now.

As for the meter meaning anything, yeah I know... I just like analogue meters.
also you could have a line of led's that light up like an EQ bar

you can still use a centered meter with n- channel jfet as shown here. the channel can be depleted or enhanced and the meter will respond accordingly. i googled this image, so there must be a description somewhere along with it, but i think it is self-explanatory.

Hehe, botched post is botched. I thought it best to leave it there unedited/corrected as it would have made the following post regarding it make no sense if removed =P.

I made one for myself using a depleted pen ink, 4x 100k ohm resistors, aluminium foil, and tape (double sided). Very handy indeed, especially during winter.

I had no idea these stuff were actually being sold though!
