So many variables, room, which cab, etc. You might like it somewhere else on a different night.......or not.
I bought my first 810 after I had been playing bass for many, many years. I had a Fender Studio Bass amp section (~180 watts, all tube), which is about 2/3 of an SVT head in power, so I thought I had the ingredients to get the tone. Well, I didn't, and not only did it not sound great, but it was very dark, almost muffled sounding. After doing the research I should have done before buying the cab, I found out I ended up with one of the blandex-constructed cabs that was known for being dark & muffled. At least it lived up to its bad reputation. I traded it off for an SVT 410 HLF, which I thought I liked in the store, but found it to be about as bad as the 810. There is no one-size-fits-all tone for everyone, much to the delight of amp makers everywhere.
