EH Hog's Foot Perf Board Layout

[Chawk]

The title of this thread is a little deceiving because I haven't worked out the perf layout yet but I intend to post it after I ask the experts a few questions.

In doing a few searches on the subject I found a number of threads on the Hog's Foot bass booster. Firstly, I ran into the schematic by Jack Orman over at the AMZ site. But then I also found Dragonfly's vero board layout which has some differences to the Orman schematic. Namely the value and placement of the volume pot as well as a the 43k resistor in Jack's compared to the 27k resistor in Andrew's. Being a relative newbie to this, maybe these are minor tweaks and don't have much of an effect on the final output signal but I can't figure them out. Are these differences negligible?

Secondly, since this is such a simple circuit could it feasibly be as easy as laying it out pretty much identically to the Orman schematic?

Thanks for reading!

I've got 1 at home, I'll try to remember to crack it open and see what the values are....although that doesnt really mean much with old EH stuff sometimes

I'd appreciate that! Thanks!

Yes, in fact, you can usually use the schematic as a perf layout for circuits in general... unless it's got opamps or somethin. I just followed the schematic on that EH boosters thing that's been floating around for a decade or more(might be Jack Orman's).

The 27k and 43k resistors are not in the same place in the circuit.

His is the "newer" version, mine is the original that has the 27k on the input to prevent the bass from distorting the signal before it ever gets boosted.

Either version works.

Just for reference, heres the other version...

 Yep, that's the one(old version). My layout is pretty much the schematic. Oh, and I used a 5133. A 2n5088 worked too, but, it might be imaginary for THIS circuit, but I think the cool little button sounds better. Shouldn't, though, because of the severe filtering going on.

Fun! I love this thing on bass for certain applications. Put it in front of a fuzz... cool! Great for instant 'flatwound' too.

One of these days, I gotta try building that opamp version. Looks interesting, might even respond to dynamics or something.

Cool...Thanks for the response. From what I understand the circuit isn't so much a "Bass Booster" but a "Treble Dampener" is that right? Is there the possibility to install a mod that allows you to adjust the amount of treble that is dampened? I guess it would sort of be like a tone stack but I'm not sure if I'm using that term correctly.

Now it makes sense! *slaps head*  Chalk that down as a newbie mistake. Thanks, Andrew, for clearing that up.
