Lovetone BrownSource. Is the Schem legit? I built it and it doesnt work.

IC1b is the recovery stage for the tonestack, the 3,9k sets the center frequency for the mids the 330k the input impedance, a commen design used in a lot of stompboxes.

If the output is connected to the inv. input the BS sounds overcompressed, thin and really weird w no crunch, useless for me. If the output is connected to the opamp out you get a good crunchy overdrive/distortion, so I'll go w Anubic's schem.

I've just checked over my BS build, after re-connecting jacks / pots and the battery clip !
I built mine as a "scratch vero" during the time with Torchy, trying to figure it out, so it was
mostly laid up like the V5 schem.
Nelsons later PDF fixed my front end wire up & gain pot, but I still have my recovery/output
wired as the V5, so can confirm that my 4u7 is wired off the output pin 7 ( in my layout ) to
the 220r etc .
This all works fine, I have a good amount of gain etc.
It still doesn't set my world on fire, but that's just my opinion, NOT the fact that it isn't working
correctly !!
I have much better OD's, so I'll be "taking back" the parts again !

I build Nelsons pdf design after several attempts at other versions and was happy at the time to have a functioning pedal. Much like the above comments mine sat there for a while before slowly being pulled apart for other effects. Nelson had a great point when mentioning that a jfet booster before the bs really brings up the quality of the sound. I have a feeling that the design of both the big cheese and this pedal tries to cover too much ground and unfortunately does so in a in a mediocre fashion. Other effects may only generate one kind of sound but do it really well. This is obviously a subjective opinion. Having said that I pulled some cool sixties sounds out of it with a little tweaking!

No OD or distortion is perfect.

If you optimize a FX for a vint. Strat it often sound not that good with a Les Paul or high gain Strat .
If it's optimized for a vint. Marshall it often will not work as good with a BF Fender.

If you clone a FX from a schem, often the part manufacturers and specifications or chip types are unknown and using parts from other manufactures can change the sound dramatically. Resistors are the only exception.

I spent most of the time not on building a FX but finding the right trannie, IC or electrolytic cap for a design or on finetuning the sound with small trimcaps.
