Re: EMG DG20 (SPC and EXG) schematics etc. [schematic]

What`s the best dual op amp for the SPC circuit? I used the LF442 for my version of the circuit for passive pickups (layout above). Sounds good, and the current draw is low, but the needed min. voltage is quite high - the circuit stops working above 7V. Not good for use inside the guitar with just o...

Fred Briggs - Pharmacy Fuzz

Has anybody ever built this circuit? The description sounds interesting, but I couldn't find a layout. Fred Briggs disappeared from the scene some years ago. https://www.google.com/url?sa=t&source=web&rct=j&opi=89978449&url=http://revolutiondeux.blogspot.com/2012/06/fred-briggs-pharm...

Re: Boss - FA-1 Fet Amplifier [schematic]

A friend sent me a diy pcb, where this cap is omitted, and it would be quite difficult to add it.

Re: Boss - FA-1 Fet Amplifier [schematic]

10µF doesn't cut any audible bass frequencies. The cap is for DC decoupling. But my question was, if this is necessary at this position?

Re: Blade VSC Preamp [traced]

According to Gary Levinson, the schematic above isn`t the newest version: "The bass boost is the same as it’s always been, centred at 160Hz, and is now a 0 to 10dB boost,” Gary continues. “The midrange boost is still centred at 650Hz, with a 0 to 14dB boost, and we’ve changed the treble boost c...
