I recently purchased a used Line 6 Spider Valve 112 from a friend. The master volume pot was very

noisy so I proceeded in trying to find a replacement part for it. Not realizing how hard it was to remove the pot

I inadvertedly desoldered the pads on the circuit board. The amp still works but there is no control on the master

volume. I would like to find out how much a new circuit board would cost me as at least I will be able to replace

that myself. I realize that I do have to go through a Line 6 dealer to get the part but would like to know up front

what the cost of the board would be. If anyone out there can help please let me know.
