    Any of you use this same preamp?

    Let's say volume goes from 1 to 10 on the volume pot, when you turn the pot, only from 9 to 10 go get volume, less than that there is no volume at all.
    It came with a Linear Taper Volume pot, so thinking it was the pot I replace it with an Audio Taper Volume pot. Same result.

    I just want to know if this is normal with this preamp or there is something defective.

    It came prewired, but when I replaced the pot I did follow this diagram:

    Thanks!

    It sounds like you used the wrong value pot for your volume control.

    250k just like the stock one, still the original and the replacement are the same value and I get the same result.

    I have no problem with my tcm2's volume pot. I had the same problem with bad or uneven volume regulation using a 1 meg pot and truly very hot pup.

    If you haven't gotten any results yet. Check with my friend fruitlabor. He knows these preamps really well.

    Do you use passive pickups?

    The preamp came prewired with all pots, 250k Linear from stock.
