Your Three Fave. Booster Pedals??????

[meexiko]

1) AMZ Mosfet Booster
2) Stone Deaf PDF-1 (clean mode)
3) Boss SD-1 Super Overdrive (I really don't appreciate the overdrive, but sometimes I like to hear its light and thin boost)

They are completely different, you can obtain a variety of sounds using them togheter (maybe only two of them, all togheter it'll be too much)

valvecaster for the fat tube boost
rangemaster boosts high end, but not harsh, plus adds some distortion
vox treble/bass booster V8401, killer after many fuzzes...turns em into monsters

[lonewolf]

what sound are you looking for? rangemaster is a good one (Tony Iommi/T.Rex/Martin Barre/Ritchie Blackmore) Brian May Treble boost has a more midrange sound ...great to fatten single coils...LPB for a clean boost with no coloring of the sound

I disagree with the LPB being clean it loads the guitar reducing the highs, this can be good or not what you want, work out the input resistance of a LPB, also what is the distortion of a LPB?
Some sim screenshots first is a simple guitar sim(one pickup 2.5 Henry 7k resistance) with the resistive loading on the guitar changing.  
To help select a boost sim your guitar and cable and the boosts you want to try.

next the graph


Note how the input resistance changes the high end tone at max treble and volume at max.  (Note the change from 100k to 470K)  As the guitar volume is turned down you will also lose some high end.

This IMO is one step selecting a boost.  Look at my first post in this thread, EQ and distortion and more are other things to think about.

I agree with Gus. The LPB colors my tone quite a bit. More bass, but it is certainly not a bad thing, in fact I like it. I'd even say an eternity or TS with the drive all the way down is more transparent (at least on my rig). Still, the LPB is my favorite boost. Nice and fat sounding.

makes sense to me too for the fact that I put together an LPB as my first boost and it sounds fantastic...I tend to lean towards the trebly side of things with my sound (tone knob on guitar and playing with just the bridge pickup on)....so the LPB sounded great for my set up...guess it was the forced fatness!

Here is an example of a boost
People seem to like the LPB but maybe want a little less gain
Here is one set to a little under X10(100k/10K). The emitter follower(EF) makes the gain more stable with output loading and allows lower current operation of the first gain stage
The input resistance is close to the LPB (it is a little higher than the LPB)
The output has an EF
Adjust C1 for input high pass.  I picked the value for open back speaker use.  You might want to decrease it more for loud volume playing or to turn this into a treble boost circuit.
R3 for bias of both transistors you need to find a compromise bias for both stages for how you want this gain stage to clip
standard value resistors and caps note no trim potentiometers


green input, blue output

looks cool, gus!!

gonna have to add this to the list!!!

[Gus]

add two parts, a resistor and cap to the sim in my post above to bootstrap the first stage and increase the input resistance.
