Title: Op-Amp Big Muff / reverse graphics
Post by: lars on June 18, 2014, 11:56:31 PM
Finally got around to doing something with that awesome Big Muff enclosure made by DavidGiandiletti. These enclosures really are top notch, and I'm sure they would make someone do a double-take before dismissing it as a clone. The great thing about building pedals is that you can make versions that never existed. My favorite Big Muff version is the op-amp version 4, but I liked the reverse graphics EHX used during the early 80's. So here is a combination of the two:

awesome man

Can you tell me where you got the knobs?

I did something similar with the electric mistress and the Davies 1400 seem small on mine

Did you design that layout? I love the wavy traces.

+1, using the old brown board material would have had me saying, "Build report? It looks like he gave an IC Muff a damn good cleaning to me..."

Very, very impressive work!

To answer about the knobs, the volume pot and knob are actually from a circa 2002 NYC Big Muff, the other two knobs I purchased from small bear here:  http://www.smallbearelec.com/servlet/Detail?no=150 (http://www.smallbearelec.com/servlet/Detail?no=150). I just scratched off the white indicator lines to give them a vintage look. The circuit trace is an exact trace of a V4 op-amp muff that I found on DIY stompboxes. I think the trace is also on Aron Nelson's site. There was an error on the ground connection for the 4558, which may be why that trace didn't take off. With a slight mod though, it works perfect.
Now if only I could find a white foam 9v battery holder to finish the look....
