True Blast Plus Question

[EIS]

Does the new True Blast Plus sound system have an external volume adjust pot?  I assume the diesel sounds will run continuously, so the ability to easily adjust sound levels is important.  The True Blast II horn and whistle sounds on my current Williams roster are obnoxiously high and I have never been successful in reducing the sound level with the internal pot on the sound board.

I have not been able to adjust the volume with the potentiameter or volume pot as it is called on the True Blast 2 made by Bachmann.
Have heard there is a light film of  something that needs to be cleaned off before you can successfully adjust the volume on the newer T.B. 2 units. Do not hold me to that as I have not tested this theory!
