Volume Pedal Question

[Michael Clark <mcl451@airmail.net>]

Hello Everyone,

With all the hi tech talk that goes on here, my question may seem silly.

I'm recording soft, atmospheric, ambient pieces with an EDP and DigiTech 
2112.

I'm using a RFX volume pedal.  One of those cheap deals from Guitar Center
(is that a hint?). 

My problem is that the pedal (or, maybe it's the 2112) isn't "even."  I'm
not able to add expression to the sound because the sound may come up to
abruptly, or sometimes, not at all.  Are the more expensive pedals
significantly better - smoother?  If so, which ones?

I've really spent mega time to get things even and responsive.  The quest
continues.

Any help is appreciated.

Thanks,

Michael
