hi, do anyone had a look at this pedal or have a schematic?
this weekend i was to a concert and the guitarist used one of those, simply wonderfull!
i saw there are gut here

but do anyone ever reverse ing. this ?

Just a guess...
Rangemaster with variable input cap...

I have some AC 127 in stock.
Time for the "Happy Saratoga" "Geranium Girl"... for only $ 200,--.

And obviously the 'original' would sound $175 better than yours...

Yes but mine will be happy, the "original" will be blues

SO it's simply that, a NPN-Ge-Rangemaster with variable input cap?
if so what range of input cap do you adivice to use?

I don't know how you tell what it is from the photo. He does have the prerequisite "toneful eyelets" though.

It´s very easy:
Have a look at the electrolytics and you will see that minus is connected to common, especially the bypass cap at the emitter - so it must be NPN. Then we have a TO-1 case, typical for Ge-transistors. The most common NPN-Germanium was the AC 127. Then we have only one transistor, a base voltage divider, the only poti between the collector and plus, and a rotary switch with a lot of capacitors which is connected on one side to the stompbox switch and on the other side to the base of the transistor. What can this be ?
Maybe this improved version of the photo can help you:

Yes, that´s correct.... but he chose the wrong name: "
Blues Saraceno". I chose "
Happy Saratoga" so I have the better Karma (happy vs. blues) from the name...

mh really nice this pic analogguru,
the circuit look really like this one dougH posted in the other section:

Seeing $350 being charged for something like that makes me want to kick a puppy.

yes.... because DougH cloned the "Blues"-unit to save and make some money
He stole the IP
But keep it secret and don´t tell it to anybody - it´s a demonstration of "Back to the Future"

cool, btw still the question for the input cap what value range do you suggest?

Get hold of a SD TweakFuzz schem and use their values.

Hey, I've never even
heard of a "Germanium Boy" until this thread!
Every other day- seems like something new crawling out of the booteek woodwork...

These have actually been around for awhile, at least in the Los Angeles area. I think I first saw them back in 2003 or 2004.

Oh yeah, that "blues" dude has been doing his thing for a couple years anyway.

I build that DougH pedal and it is simply awesome! Everything I need! Boosts my Dumble quite nice without getting too gritty (almost clean boost).
I used some germanium NPN OC140's for the trannie and used the next values for the input cap:
0.005
0.0068
0.0082
0.01
0.015
0.022
0.033
0.047
0.068
0.082
0.100
0.220
Every cap has its own voice and feeling; quite nice. Over 220 nF my tele's bridge pickup get's too muddy; at 220 nF it sounds like my les pauls neck humbucker
Under 5 nF I also dislike the sound
