FET Mini-blender
Posted Tue, 2010-03-30 22:16 by Harold

Project description
A nice and simple blending circuit to blend an effect with yout clean signal, based on this schematic by Sean MacLennan.
This design blends up to about 90% wet or dry and only works correctly if the signal's phase isn't inverted in the blended effect!
I've used it a couple of times for adding fuzz or distortion to a bassguitar without losing any low end.

Q1
Submitted on February 11th, 2012 by AnonymousCan I use a 2N5459 instead of a 2N5457 ?
That should be no problem.
Submitted on February 11th, 2012 by adminThat should be no problem. The FET is just buffering your signal, any N-Channel JFET with the same pin configurations should do.

Submitted on December 5th, 2010 by AnonymousI am no electronics genius but I have just built this unit for my Pedal Steel Guitar and it is brilliant. I hadn't realised there was a strip board layout for it, otherwise I'd have had it done yesterday. Anyway after spending a lot of hours and money on other projects trying to get what I want,I now have it. Thanks to whoever designed and submitted it. GREAT. Dave.
