This pedal sounds better than the demo. Big fat fuzz. It's in my top ten now. I also changed the 1K directly below the 470k to 10K as both final schematics at FSB indicated this - not sure how much difference it would make. I socketed it but left the 10K since it sounded great. i tried the 22u for input cap but swapped back to a 10u.

I'm thinking that the person who drew the schematic might have used the wrong multiplier when reading a component value. Last night I tried the fuzz face section on it's own and missing out the 1K resistor from the third transistor to the fuzz pot bought the voltage at the collector of the third transistor down to 4 volts from 6, it sounded much better. I think this resistor here should be 100R not 1K. Now to fix the first transistor bias....

Just because I had it socketed ( because I had to combine two resistors to get to the 590 value and wanted to replace them later if it didn't work ), I tried some different values in the spot where the layout calls for the 590R resistor. I figured since it was connected through the 8.2k to the collector, it might have some thing to do with biasing ( not sure - I'm a paint by numbers guy at this point but I'm learning )and the distortion level. Jumpered it and got nothing. Put in a 3.3k and actually got a little more kick. I then went overboard and put in an 18k. Sounded very gated and voltage starved like some of the booteek makers put in an external pot to do. Settled on a 10k for the moment. It now sounds like a fuzz and has more gain and output. I may stick a trimmer in there and tweak to an even better sound.<br /><br />For you guys who know your circuits, I wonder if tweaking/increasing the 820R resistor would give any more gain...what do you think? Also, I wonder if there is a way to add a little more bottom end ( I think I'd rather add low end than subtract the highs, if that makes sense ).<br /><br />ThanksAnonymousnoreply@blogger.comtag:blogger.com,1999:blog-6847048658257278783.post-46913922964811647432012-07-15T14:54:28.129+01:002012-07-15T14:54:28.129+01:00Forgot to mention, I did sub a 220uf for the 470uf...Forgot to mention, I did sub a 220uf for the 470uf because the 220 was physically smaller.

More like a mild overdrive than a fuzz ( that is with my Strats - humbuckers do drive it into a little more dirt ). It is very bright with the tone turned anywhere above 9 o'clock. I haven't seen anyone else mention this but I have to turn the volume to about 2 to 3 o'clock for unity. I do get a tiny bit of sputter on decay of a ringing chord, but not enough to be annoying. I may try some higher gain trannies but it looks like dexxyy has already tried this with little result. I'll set it aside for a couple of days and decide...<br /><br />Little disappointed. Not a bad sounding pedal at all - just expected something a little different from the demo. That being said though, with the pedal maker being from Texas, I could see how this could be applied to the Texas Blues kind of sound. SRV and others tend to not have a lot of gain on when soloing - just typically a bit of grit added.Anonymousnoreply@blogger.comtag:blogger.com,1999:blog-6847048658257278783.post-71099403687513330572012-06-10T19:59:33.988+01:002012-06-10T19:59:33.988+01:00I built it and got no sound at all.
