## Questions & Answers

**Q: I need a micro amp that I can run a mic through...anything available?**
A: I doubt this will fulfill your needs as it is a signal boost pedal that feeds Ito a guitar amplifier which then feeds into and drives a speaker ( as in Celestion ) for example.  The name micro has nothing to do with a microphone.

**Q: Good for an oasis and kings of Leon tone?**
A: This pedal simply boosts output  (Loudness) so will push a tube amp into breakup/distortion if your pickups/guitar volume knob will not, similarly distortion pedals. It is excellent at what it does though a little pricy. This will not make you sound like anyone, stomping on it is a bit like having an extra turbo charged  guitar volume knob .

**Q: is it true bypass?**
A: Clearly this pedal both is and isn't true bypass
