Xotic Super Sweet Booster

Pro:
- 20dB of gain is enough for everything from a subtle solo boost to pushing your tubes into full-on overdrive
- 4 external trim pots: high cut, hi mid boost, low mid boost, bass boost
- true or buffered bypass (internal control)
- add headroom by supplying up to 18V
- sturdy, solid construction
- miniature format lets you squeeze it onto a tight pedalboard

Con:
- tiny gain control
- most of its dB range is found before the 9 o'clock position (roughly equal to the 16 dB of the super clean)

If you're looking for a booster, look no further. If you want enough gain to go into overdrive, pick the super sweet. If you prefer a less sensitive gain pot, go for the super clean.
