Built it, played with it for a while, no problems with the build, sounds great, but I have some questions:<br /><br />1) How can I increase output level?<br />In my case, output transistor has almost no effect on the output level, played with standard 2222, 5088, 3904, etc., the difference is small.<br /><br />Diodes have much bigger influence:<br />- LED (1200+ mV) rapes amplifier with loudness, and it’s definitely not a fuzz, more like power-amp dist.<br />- 4148 (650 mv) is ok, but they sounds pretty ear-piercing, and I want germanium flavor, with soft highs.<br />- germanium diodes that I have (250-300 mV) sounds so quiet that even with the output pot at max, a booster is needed to get to unity.<br />I'm thinking bout 2 germanium diodes in series for each of two sockets to reach 4148 voltage, but right now i have only 2 germ diodes, so can`t test this, but it might work.<br /><br />What are your opinions and ideas on this?<br /><br />2) Taming high frequencies.<br />I haven’t found a single solution for tone adjusting, except for a complex 2-band equalizer like Behringer Superfuzz SF300.<br />All "tone" mods that I've seen are about adjusting scoop at 1 kHz, and there is nothing about cutting everything beyond 3(?) kHz.<br />So far I have only learned two ways: I can increase value of the 2.2nF cap(near the input wire), or/and put cap from output to ground. <br />In this case, the maximum that can be done is to connect capacitors on a rotary or toggle switch, and get 2-4 “presets” for highs.<br /><br />So, how else can this circuit be modified to achieve tone adjustment as we typically understand it?<br /><br />Thanks!dmhttps://www.blogger.com/profile/04249271563874625012noreply@blogger.comtag:blogger.com,1999:blog-6847048658257278783.post-58624214360521051102021-05-23T11:30:49.114+01:002021-05-23T11:30:49.114+01:00Hello everybody! very good fuzz but i have a probl...Hello everybody! very good fuzz but i have a problem.

SW3 is supposed to go to 47k and then also 10k to ground, but in the layout it doesn't look like the 10k goes to ground. Am I missing something? I fully admit that I might be, I'm pretty new at this. Also I might just be looking at a different schematic than the one used to make the layout.<br /><br />Thanks for all your work.Borishttps://www.blogger.com/profile/08749391575733516700noreply@blogger.comtag:blogger.com,1999:blog-6847048658257278783.post-36137412826934186592021-01-02T05:15:32.187+00:002021-01-02T05:15:32.187+00:00Hey there, loving this site.

This pedal, the schematic shows SW3 going to 47k and 10k to ground. In this layout the 10k isn't going to ground. Is there something I'm missing, or is this a mistake? Or is the schematic I'm comparing this to wrong?<br /><br />I know this is an older layout, but if anyone sees this I'd love to know. I'm going to try wiring the 10k to ground either way.<br /><br />Thanks again.

The spacing of many trimmers will mean they stretch across 4 rails. You'll notice on this layout, its only supposed to stretch across 3 rails. Hope that makes sense!

Than I measured resistance of balance pot and it was damaged. Despite of pot turning it has always one resistance out of pot range (pot is rated 0-50kOhm whereas its resistance was about 400kOhm) After replacement the effect behaves perfectly.

Once effect is engaged the output level drops significantly and only cranking up the amp to max makes this effect output signal audible. I did lot of troubleshooting f.ex. replace electrolitic caps, replace transistors but problem still persists.<br />I would be appreciated for any ideas.Iczikohttps://www.blogger.com/profile/01820509657980412941noreply@blogger.comtag:blogger.com,1999:blog-6847048658257278783.post-10615062105112867542015-11-19T01:04:52.579+00:002015-11-19T01:04:52.579+00:00By the way i numbered the Transistor left to right...By the way i numbered the Transistor left to right being Q1 near 2,2nF and Q6 the in top right corner near the balance wires!!Anonymoushttps://www.blogger.com/profile/03212442967053630501noreply@blogger.com
