lpb-1 vs lpb-2

[xnery]

Has anyone here built both the LPB1 and the LPB2? How do they compare? What are the differences and what do people prefer?

The #1 LPB is the original one that plugs into your guitar directly. It's a little square box about the size of a wall wart.
The LPB2 is a pedal version of it. They both are the same circuit so they both sound the same. A nice boost for a tube amp!

  Made with larger value input and output caps [somewhere there's a page with many LPB variations on it] the wires can be used to splice in series values to trim bass. You could also quite easily add a LP filter cap.
  Or socket caps
   or switch caps...and socket transistor, anyway I think the bias arrangement is the same [maybe there's two]. probably you'll find one or two of the variation most useful from the batch...'screaming' one is crazy trebly.

A very nice Booster... I think both LPB-1 and LPB-2 are the same as Basicaudio said... I tried once to put a Darlington transistor, never worked (I didn't tried too much ), my mistake or some kind of circuit limitation??? I used MPSA13.
