Last mont projects II: Scrambler clone (PCB, layout, pictures)

[yeeshkul]

I built Ampeg Scrambler clone. It is a weirdest fuzz i have!
The trannies were purchsed at smallbears', i used 2N3904(Hfe 260) for Q2 to get the factory voltages.
Diodes 1N456 were purcghased at Banzai's web shop.

PCB and layout

the PCB is designed to be fixed straight on the pots (with 4.5 cm distance of the pots)

My build in Hammond BB

Awesome sounding pedal. What transistors did you use?

Hi, i used exactly what i mentioned above - 2N5306 and 2N3904.
Correction: the 47uF cap (the one above the 100uF) has the "+" side towards the clipping diodes - NOT like on the picture. It was working even with the cap wrongly oriented (see the picture), but i suppose the cap doesn't like it.
