that's assuming the amp eq is lacking. if it isn't, an extra eq is just another box that gets in the way. if it is, it can help.Completely agree there. Tons of people on here use VT bass or BDDIs. Both would be extremely helpful if you got a cheaper amp as they can help beef up or fill out your sound where your amp EQ is lacking.
not that i'd call sansamp pedals eq, though. they do have eq functions, but they do a lot more, too.
