I just noticed something for the first time. This is regarding my Custom Shop Reissue Vibroverb.

When using the Vibroverb with the Cesar Diaz modification in the ON position……and with the Volume knob for the Vibroverb channel rolled all the way off, I’m still getting signal through the amplifier and to the speaker.

As I roll the volume on there is this sort of filter/sweep effect between say 1.5 and 2 where the volume goes up and down slightly with a slight EQ change too. The vol goes up from 1- 1.5 then drops slightly and gets a tad bassier from 1.5-2 and then just over 2 everything gets normal and the volume starts to increase as it should.

Using the Normal channel this doesn’t happen, volume goes up normally from 1-10.

With the Mod switch off, in Stock position, the volume works normally from 1-10 as well using either channel.

Does anyone have one of these and if so……does yours do that?
