Lehle Little Dual II

I like the switcher. Great quality and great straight through sound with no discernible affect on frequency response. However, the switches aren't silent and with a guitar like a Jaguar or Jazzmaster with 1 M ohm pots, the input impedance of the unit is such that a tone suck happens. I have to use a TC electronics Spark in front when I use an offset to match the input impedance. Not a disaster but just beware. Otherwise it's great!
In fact, if you use this unit right at the end of a stereo chain it sounds fantastic and I have gone on to buy a D.Loop SGOS too. The only issues it has, for me anyway, is plugging a guitar directly into the input.
