lost Mini-boost mods?
A few months ago I built a minibooster.  
Someone posted that to reduce some of the bass-change one of the caps.  
Well, I had planned on doing it 'one-of-these-days'.  
Since then, the board was cleaned & the thread is gone.  
Anyone know the mod for this?

Lower the cap value on the upper JFet. It is the cap from gate to source. Lower it to say, .1uF for a treble boost. Play with different cap value here to see what you like.
