Any suggestion to replace a JB?

[Michel347]

It looks like the tone knob is a master tone. It is adding restancevto the JB and probably muddying it up some. You might consider removing the master tone pot from the volume pot and moving it to the neck pickup on the switch that would open it up quite a bit

Oh, before swapping it I changed the tone pot for a no-load one, which is basically doing the same in the no-load position, still found it too honky and compressed to me, the Custom SH-5 is a good fit to my taste, lots of highput and more balanced.
