hey... vanessa uses many combinations of pianos in her studios. she even uses older piano derivatives of pianos (for example, the harmonium).. anyways, on BNN, Nessa has a piano with a very bright, clear sound ( a normal recording piano). If you want that kind of piano, just try out different pianos or ask pianos that have a brighter color to it... However, i have to warn you, a piano that has a bright color to the sound doesn't really sound good acoustically.. so try out every single piano you can, because every single one is made differently even if they are the same brand.
anyways, i'll give you some famous brands of "affordable" pianos:
roland
kawaii
yamaha ( i think vanessa said that these are not bad)
