A friend wanted a compressor so I made a couple for him to pick from. An Engineers Thumb (Special thanks to Jon P for helping get this one up and running) and a Keeley Style four knob. Both sound really good and make me want to play some Brad Paisley!

Seriously loving those graphics :)
Nice man! Great looking builds. What are your thoughts about them? Any major tonal differences.
very cool, what values did you use for the "non stock" attack, release and threshold controls on the engineer's thumb? how well do they work?
Yeah nice job! Squish that signal man... you keeping them both?
can you told me something more bout those mods? I'm really curious!
Thats a class couple of compressors there.
I really like the look of the Great White Comp; looks like a studio compressor with all the proper controls available.
Have you tried running anything else (drums, bass etc.) through the engineers thumb?
Indeed, both of them look great! But I like more the Great White Comp! It looks SO versatile! The next days I'll build two Flatlines (the one for a friend), and then I'm going for an Enginner's Thumb! It's a must! ;D

Excellent work! I think your friend will be very happy. :)
Great Job! really dig the look of those! 8)
May i ask a bit more details about the engineers thumb?

here is the designer's site, in case you haven't seen it: http://www.valvewizard.co.uk/engineersthumb.html (http://www.valvewizard.co.uk/engineersthumb.html)
the man is a genius, by the way. check out the glass blower, a booster that can produce 12Vp-p signals on a 9V battery.

I want to build one and give it to someone I don't like, telling them to run it first in their chain. Booom. hehe.
Thanks for the link ;)
Wich components have you replaced with pots?
Here's what i think have been done, correct me if i'm wrong please.
R11 have been replaced with a 100k pot for Attack control.
R12 have been replace with a 1M pot Release control.
C8 is on a SPST switch
Can't see what you did for the Treshold control.......... ::)

They're all in one of MerlinB's schematics, I think the simplified scheme (there's one that has the mods in red). The Threshold is the 1M Vb resistor on IC1 Pin5. My personal recommendation is to be prepared to use minimum series resistors with the Decay (Release) control and the Threshold if you do those mods; you can easily introduce pumping or other "bad" settings.
Say, whose layout did you use for the Keeley? Really like the look of both of these though!
Glad you all like them! The Engineers Thumb is probably my favorite graphics to date. The layout for the Engineers Thumb is here http://www.sabrotone.com/?p=2901 . The layout for the Keeley Style comp is here http://tagboardeffects.blogspot.com.au/2012/07/keeley-4-knob-compressor.html . The extra controls on the ET are somewhat useful but not spectacular. I get some funky noises with the release turned all the way down. You still can dial in some great tones but it may be over kill. If I were building another one for myself I would probably not add the extra controls. As mentioned before the original design was done by Merlin/Valve Wizard.
Thanks for the heads up guys! :)
