Volume Pedal Taper Issue

[ninjadave7]

Hey all,
I have an Ernie Ball VP Jr, standard volume pedal, and recently put a buffer in front of it. Since then all the volume change happens in the last 10% of the taper, making it unusable really. Ernie Ball says I need a 25k VP, so i put a resistor on the 250k pot in mine and changed the overall value to 25k. It's still not working though, no change really. Any ideas or suggestions?

Would it be possible to place the buffer "after" the V pedal?

Sorry but that's not the same as having a 25K pot.
besides that, can anybody post the schematic of said pedal?

From the Ernie Ball Forum:
"When would I use an "active" 25k pedal as opposed to a 250k/500k "passive" pedal, and why?
A:
Passive vs. Active: Whenever there is a passive signal leading into an EB pedal, the 250K or 500K pedal is recommended (mono VP & VPJR 250K and stereo 500K VP pedals available). Whenever there is an active signal (powered preamp in the instrument, effects loop, etc.) leading into an EB pedal, the 25K pot is recommended (stereo VP and mono VPJR pedals available). If an active signal is placed before a 250K or 500K EB pedal, or if a passive signal is placed before a 25K EB pedal, then the consequence may be that the swell of the pedal does not act as designed. Either way, as stated above, try whatever combination you desire, and determine if it works for you. All of our volume pedals are designed to be as transparent as possible in a signal chain. However, whenever you add any component to a signal chain, the signal will change whether it is audible or not. Keyboards are generally served best by the 25k pedals as well."

Thanks guys. I think I'm just going to live with it for now.
