I have 2 vts at once somehow and I honestly can say that the distortion settings on the vt sounded AMAZING through a clean vt. He maybe pushed the VT as distortion into the deluxe as his cleans.
MXR has a phenomenal warranty. I used cheap jacks once that broke off in my BOD and they were gonna send me a new one for free, even after I told them it was my fault. Ended up fixing it myself but still give props to there c.s.
I had that problem recently when I added a few more pedals with my one spot. Seemed it didn't get enough voltage so I had to re power everything. Now its happy.
