One I just tried here required 13K to just barely hit full feedback. You would want more than that to have some headroom so you know when you are safely at 100%. >so that you could use a 10k pot (with 10% tolerance) and still >get 100% feedback. or not. >The FV-50L is 25K ohm and hence there's quite a good >proportion of it's sweep that doesn't do anything. It's 20k. >It's quite hard to set the feedback to an accurate number >on the display using the FV-50L. For me it uses 72% of the throw for the full feedback range. (just measured it.) Since I like to have a good size zone at the top of the range that I know is absolutely 100%, that is about perfect. If you recommend a pedal that has a 10k pot, it will not work for a lot of people. If you recommend a pedal with a 50k or 100k pot, there will hardly be any useable range. That is why we have long recommended the 20k Boss. We know it works on every unit across various component tolerances, and it has a reasonable range of use. The EB with 25k would be pretty close and probably work fine. you could always try soldering different resistor values across the pedal output (parallel with the internal resistance) to see if you can find a range that makes you happier. kim ______________________________________________________________________ Kim Flint | Looper's Delight kflint@loopers-delight.com | http://www.loopers-delight.com
