This thread.... LOL. Anyhow, I'll bite... it depends on your usage of boost. For gain boost - you can just purchase Digitech Bad Monkey or Fulltone Fulldrive II. If you put it before your drive, it will add an additional GAIN stage to your existing Overdrive/ Distortion. It may not add too much volume but, it will provide you singing sustain and more grit ! For clean boost - check my thread http://www.tdpri.com/forum/stomp-box/576286-tremolo-boost.html but, agreed with some, you also cannot go wrong with an MXR Micro Amp for very very clean boost. I also had an EHX LPB-1 but, it adds a bit of bass when I engage it hence, had to sell it.
