Title: Big Muff OpAmp
Post by: selfdestroyer on November 30, 2013, 07:05:47 AM
Layout by Scruffie over at FSB/DIYSB. This has been in my "maybe I will finish it later" bin for more than 6 months. I have made a goal for myself to finish what I started before I build any new major projects. So here I am with another finished pedal for the board.

My number 2 favorite muff, right after the Violet Rams Head. When testing this thing I got instant Smashing Pumpkins Siamese Dream memories.

I like the color and the stamp lettering.  Smashing Pumpkins worthy fuzz...that's killer!  Makes me want to play Pisces Iscariot now :).

Nice job...and with op amps, I have to check that out!

Very nice! I love that you took the time to bend the greenies over. Wait... that somehow sounds kinda dirty!  ;D

Thanks for the kind words people. I had a blast late last night playing with it. It just a great sounding 90's crunch.

I have been wanting to build one of these as well, but have a fear of it not working with EMG humbuckers as well as it would with single coils. I love the sounds achieved with this on Siamese Dreams.

I wonder if you could back off the intensity some and get a convincing Clutch sound?

Just an educated guess but I think it would work fine with actives.

Glad to see my layouts getting some use, I actually improved this one a bit a little while back for someone that wanted to use it for a small run so if someone wants it... however Bean is about to release his etchable version which is most likely (definitely) better, I did these years ago!

Most muffs are ok with active pups.

This nails it, a Muff has to be on my to-build list for the new year!  :)

Really came out great, and the lazy Greenies look cool in there.

Really like the look of those stamps. Is that 3PDT pcb your own design?

Thanks, it is. I took some of the ideas from 1776Effects 3PDT board and wanted to make one 1590A compatible and etch-able.

The traces are pretty small but I am able to make them with toner transfer method without any issues.

Thanks for sharing this. I really like the way you laid this out. I had done one myself but like this much better.

No problem, glad its helping someone else. I am working on a little better pads for the 3PDT this week. I think I am going to switch to the PCB mount 3PDTs since they fit better than the solder lug versions. I am about ready to put in an order on some today.

That sounds interesting. I was thinking about ordering some more switches soon. Where do you get the PCB mount 2DPT's from?

I never ordered PCB mount 2DPTs but I do get 3PDT's from bitcheslovemyswitches.com (http://bitcheslovemyswitches.com) most of the time.
