Blue Voodoo mods

[Steven]

Can anyone help? I bought the blue voodoo mod book to only find out that the mods and schematic in Brian's bookis not the same as the blue voodoo I have. Mine is the Blue Voodoo 60 Combo with 4 preamp tubes and 1 phase inverter. he one in the book has 3 preamp tubes and one phase inverter.

I've bought the Blue Voodoo mod guide as well and as far as I recall, the best way to go about it is to diagnose what the "problems" are with your amp that you'd like to remedy.  That said, one of the videos Brian goes through and explains what each gain stage of the amp does and how different bias choices and voltage dividers affect your tone.  I'd suggest you write out a list of what you don't like about the amp and print out a schematic, at each gain stage (tube stage) calculate and write down just what freqs are cut and what freqs are clipped.  I know everyone wants cookie cutter mods, but IMO they most often fall short since high tolerances of components can change how an amp/pedal sounds from box to box.

Try contacting Crate and see if you can obtain the schematic.  I'm curious how these sound over the head versions.  I think there's also a blue voodoo 50w head (the bv 60 is 50 watts too).

Steven,

Did you ever get a copy of the correct schematic for you BV6212?
