Question: New Majesty – Volume Poti crackles

I purchased my new Majesty 4 weeks ago. Since 3 days I recognize a crackle and scratching sound if I use the volume Poti, even in push position. This is more pronounced if I use high gain sounds. Especially the first third turn from maximum gain to low gain is affected. I do not have this with my other guitars.
Thus the majesty is brand new I am very frustrated and cannot belief that this might be due to dirt or dust in the pot. Is this a defect in the preamp? Any suggestions?
Thanks in advance
