volume boost on effects

I have built a few effects now, and have noticed that on some of them the output volume is less then the bypass volume. Is there some kind of fix for this, someway to mod the circuit? I tried a search for this topic, but couldn't find what I was looking for. Many thanks.

TIP:

Search for "volume recovery"   :D

  Which effects...
   and have noticed that on some of them the output volume is less then the bypass volume.
  This could be normal, and compensated for using MM"s above suggestion.
  With that said...Quite often posts with "the output volume is less" in them are solved by applying DEBUGGING. [See DEBUGGING, What to do when it doesn't work].
  I would verify the circuits names and optimize functionality before modifying any of them.

I agree with Pete.
There are a few builds that yield less output than bypass but not many.
Knowing which you are referring to could help us to help you!

  There are a few builds that yield less output than bypass but not many.
  Safe to say most effect circuits are intended to do at least unity.
  I can think of very few examples of circuits not intended to do +/- unity, unity+, or unity volume between efkt on and bypassed, when correctly built and biased.

The effect that first comes to mind is the Vox Treble Booster ( http://aronnelson.com/gallery/album18/VOX_TREBLE_BOOSTER ). The effect volume even at max is less than the bypass volume. I checked my work against the vero layout and everything looks right. Thanks.

Well, not to be sarcastic, but anything with "booster" in its name should not be at less than unity. Check your transistor pinout, and your switch wiring.

Well, it sure does boost the treble. As for the volume, well that is a different story. I checked the transistor, and it is correct. I'll keep at it. Thanks guys.

Don't forget to check cap polarity, if applicable.

That particular TB has the volume at input ! which is sort of like turning "down"
your guitar.
The Dallas Rangemaster, has the volume pot connected to the tranny collector/9v node
and DOES provide some vicious "boost"

I would recommend the RM , either PNP or an NPN (Range Blaster) version, for more boost and the
ability to drive an amp input ( tube amp )
