You know, a vac and a hair dryer both move air, but are no way functionally similar, and that is how I see this circuit - it is so far functionally removed from what it claims to be that the claim just becomes an excuse to associate the circuit with an iconic amp, and in my view so unjustified and misleading as to be simply dishonest.

At least they're not trying to make money with that circuit...
But it's quite disappointing when I see a circuit that claims to be a clone of something I like, and when I build it sound totally different.

Wow michel, I knew that people here would help you out, but holy cow!  That should give you plenty of ideas!

Yeah, I surely have work for the next 3* months.

*Or more, everything depends on how much money I can save :cheesy:

If you follow the link I give above to a different thread here you will find my FET preamp design.  This should be pretty clean, and also give a bit of characteristic curve distortion at high drive levels.  This circuit shows a tonestack of my own design, but there is no reason why you couldn't substitute the Fender or Marshall tonestacks from the Redcircuits design.  While a power supply is shown any clean supply from 18 to 30 volts should work okay.  @Stormbringer now has one of these near completion.

I think I will use your circuit the way you posted it, the magic is in testing original, leaving the modifications for latter, I don't have much time left for this week, but i think I can do a PCB layout for it next week, then I can see if I have all the parts at home to build it, thanks for the help :tu:

But when a goose bites, he is also setting up to hit you.  He grips a bit of your flesh in his strong beak, so he can hold on and beat you with his very strong wings.   And that hurts.  It can even break a thin arm bone.  THose wings can take those heavy birds in the air and fly a thousand miles.  With bony knobs along the edge.

There's a guy who lives near my house who keeps like 10 of them in his yard, no one dares to get in his yard, they're pretty aggressive, when they come at you in groups it's better to run like hell.

Nice lizard, there's a lot of them here in the summer(not the same type as this one), I love them, my neighbor give food to them and they just stick around here harmless(unless someone threat it).

Wow, Thanks for taking time to analyse this circuit, I was searching about Redcircuits for the last few days, and surely didn't read good things about them... I will give it a try, but just because it's really cheap to build and because I already have a power supply that can handle it, about how it would sound, I was expecting something more clean, I'm used to use strong pickups, so I think my guitar will easily overdrive it, I will search for another clean preamp, for a dirt preamp I think I will try the JCM800 fet version, and the Dr boogey, I read about a guy who used dr boogey as a preamp running it with 18V.

Welcome!   :dbtu:

handmades.com link vectors to a sales site for "MoneyFreedom.com" for me, however there is a site in Brazil http://www.handmades.com.br/forum/ which deals with "pré amplificador".

This might work (to English);

Oh look, a FET preamp without any trimpots!   

Oh, I'm sorry, I actually was referring to http://www.handmades.com.br/forum/ (I always forget to type the ".br")

That clean pre-amp is kind of good, just needs to be tamed, but I'm more into trying out new pre-amps to see if I discover something I like

Now that you said that, it's really weird, I didn't found much more about this circuit... guess I'll have to try it to see if it works

I've actually had good luck using a Little Gem as a preamp (even though it is designed as a small power amp).

Sorry, I've got it wrong when I first read.

**edit**
Also, I forgot I made a layout for the Dean Markley K20-X preamp here: http://www.ssguitar.com/index.php?topic=1885.msg12904#msg12904

I haven't built it myself, but a few others have and it works really well.  I have the amp it was originally designed for and love it.

Thank you Joe, is that littlejem a miniamp or its a preamp and a power amp in the same board? I was planning to build a 386 based amp to have on the workbench, it's real useful, about the Dean Markley K20-X preamp, do you mind if I rearrange your layout? I more used with etching pcbs than the perfboard.

Hi, good morning everyone, first I'd like to thank the moderators for this amazing forum, I've been reading some threads for some days and decided that it's time to participate more.
It's been a while since I've started building guitar effects, for my own use, and over an year that I've built my first amplifier, a TDA7294 with clean an dirt preamp, the preamps were both found at www.handmades.com, they call it "pré-clean" and "marshallizer", the clean channel has a good sound, nice to tune, but it really messes the tone of my pedals, I can't find a good distortion tone combined with that clean preamp, the dirt is the same, I really didn't liked it, it has a good distortion, more to overdrive, sounds like a low power marshall amp, but it's awful with muted notes, I have two guitars, one is 20 years old with weak pickups, and the other is my first guitar, with more powerfull pickups, both sound weird with the dirt preamp, I'm using a handmade Sans-Amp GT2 as a preamp for now, that one is awesome except for the fact it doesn't have a "mid" control. Now I'm having more time to work on my projects so I decided to find a good match of preamps to use on my amp, I'm looking all over for different preamps, nothing special, I just want to try a lot of them to find out what I like, for a clean I wanted something that wouldn't mess the tone of my distortion pedals when I use them, and for the dirt I wanted a more defined distortion, doesn't need to have too much gain, just enough.
Now, my point is, what I want with this thread, is to talk about it, to know what do you guys like on a preamp, what suggestions of good ones do you know, as I said on other thread, I'm willing to build a lot of them to try them out, and I'll be contributing here every time I get one working, I can do layouts, more complex circuits can take a longer time, but I'm persistent. Before I knew this forum(last week), I found out this one while looking after solid state preamps:
http://www.redcircuits.com/Page120.htm
Does anyone heard it already? I have a layout done for this one, as soon as finish building it will be my first release here.
