Title: Bacon Bits gain
Post by: gordo on November 24, 2012, 01:17:03 AM
I'm too lazy/stupid to do the math to calc gain on the Bacon Bits, but what kind of boost should I expect on this thing?  Seems to be working just fine...full counter clockwise appears to be about unity but cranked is probably about (I'm guessing here) about a 10 or 12dB boost?  I was thinking this thing would be just roaring, given the amount of headroom on 18v.

Update...I have two of the boards and swapped out a TL072 for the 272 on one of them and very little difference.  Maybe kick up R5 to about 200k or so?  I don't want to bugger up the freq response and the BB does a fine job of sparkle and keeping the guitar volume control linear and bright if it's first in line.

Gordo, I also don't want to be rude, but sometimes this happens. I don't have a good grasp on what you're asking, so I'm not sure how to answer you, nor have I built the bacon bits. You admitted to being lazy above, so perhaps you just need to to put your head down and figure the math, or experiment a bit.

Thanks Jacob.  Yeah, I was a bit crabby last night.  Looking for the easy way out.  Bacon Bits sounds great and makes the guitar knob very smooth and linear without losing any top end.  I just need to figure a way to get a bit more gain out of it.  Even cranked there's not a lot of level on tap.  Then again, maybe that's the point.  I wanted to find out anyone else's take on it.
