Lehle Sunday Driver SW or Mesa Clearlink Send?

[Steve Browning]

I don't use any effects but I do have a (Lehle) switcher to allow me to change between passive and active basses. I am currently using an old Palmer Y box with a buffer in it between the switcher and the amp (which is a Mesa).

So my plan is to change the Palmer unit for either a Lehle unit or the Boogie. Does anyone have any thoughts on either of these? I certainly noticed a difference when I first started using the Y box so am pretty sure having such a unit is worthless.
