Thanks for that Steve. I totally agree with the controls / connectors place=
ment.
As for the calibrated input gain, the fader was to have a 'nominal' 0dB gai=
n at 12 o'clock, but I'll incorporate an internal trimmer to make it exactl=
y so such that the switchable input gains are effectively calibrated.
As for the battery, I intend 4 AA's inline, but I could oversize the bore s=
uch that you could either insert a preloaded tube of cells or individuals.
Battery indicator, hmmm, can of worms. I'll have to give that some more tho=
ught. Tricky!
Anyway, thanks again Rob
