I had a VT bass deluxe set to OD-dist-fuzz, when I put the VT behind the other dirt it made all the other pedals sound like it. When I put it in front of my dirt it sounded like mud. Lots of people say it will work and I was told that my problem was that it won't stack well if the sansamp is set to distort. I guess I'm saying, be careful. I liked the VT but I sold it anyways.. I prefer my sft at 18v which is similar but sounds more organic set to OD but the sft won't do the clanky highs or the low lows the VT would do and the sft is easier to dial in as it sounds good at most settings.
