    I don't think the pot you heard of would have a longer travel. Probably different taper like 52Bill mentioned.
    A longer travel pot would require a longer rack and maybe even a deeper cutaway for the heel to rock back further.

    Or a pot gear with fewer teeth, so each inch of rack travel turned the pot shaft more.

    I considered that already, I might buy a bunch of cogs and try it out, the results would be what im looking for, I might need to grind the pedal at the back so it can go lower.

    If it's just the bottom end you don't like you can reduce the range of the wah by adding a resistor ( or pot) between ground and pin 1 of the the wah pot to avoid the bassy end that you don't like. The value of the WAH pot is not shown (100k?) so I suggest a pot wired as a variable resistor of half of the value of the WAH pot would be suitable. You can then tweak to get the desired range.
    Interesting to see these are the results:

    dunlop 1990 pot - 124k
    hot potz 2 - 104k
    chase tone pro 100k - 96k

    Im gonna play around and see what happens when I add resistors like you suggested, I cant believe it didnt occur to me to use the MM on the wah pot already.
