OT: proel volume/expression pedals

[rich <rich@nuvisionsca.com>]

hey all,

i know this has been discussed briefly before, but i'm looking into 
buying a few of the Proel stereo volume pedals.  They have 100k 
linear pots in them.

can anybody give a brief analysis of this pot for use as an 
expression pedal?  their initial use will definitely be for volume 
pedals, but can i use them as expression pedals?  how would they 
compare to the expression pedals i have now?  i have a boss EV5 and a 
line6 pedal.

i know the big aluminum ernie ball pedals get used as exp. pedals a 
lot.  what is the potentiometer in those pedals?

any info is appreciated.  does anybody have any experience with the 
proel pedals?

best,

rich
