Hmmm... maybe the led illuminates a double LDR which is symbolized by 4 dots inside a circle (in the left lower corner - in parallel to R19, R20) ?

Re: Shiino Vesta Fire Compressor (with schematic)

R19-D5 form a voltage reference of 0,65V R20-C11 acts as a noise-filter for the voltage reference even when the main purpose of R20 is for the release time. Attack is determined by R18+C11 D4 is there to reduce the voltage reference to zero without a (sufficient) signal. Purpose of this arrangement ...

Re: German tube stompbox schematic [traced]

I don't know why, but I have the feeling that I am missing a (680 ohm ?) resistor at the cathode of the first stage....

BTW, I didn't know, that this guy is still alive & active.

Hi! does anybody know which parts must be changed in the pedal for a kinda metal sound? and how to add q, gain, bass and treble controls? Is your Google broken? :horsey: This thing is a piece of cheap crap with a circuit similar to the original cry baby, and with all the faults of the cry baby. Per...

Re: Panther Distortion DI-10 traced [schematic]

The 47k resistors in the tone control are still wrong. They should be 27k, according to your pictures.

And BTW:
the resistors near the tone control are - according to the picture - 27k and not 47k.

Re: Panther Distortion DI-10 traced [schematic]

Schematic is still wrong. there is no cap in parallel to the diodes, this cap is after the 27k-resistor near the tone-pot

Now there is only missing a 22k resistor (maybe 2k2) between pin 6 and 7 of the second opamp (instead of the short).

I bet the tone control is drawn wrong too and should look like one from a tube-screamer - please verify.

Re: Dunlop - Band of Gypsys Fuzz Face Mini FFM6

Now let's see: If you have a tube and someone writes "transistor" on it, does that mean that it is a transistor or still a tube ? If someone writes "clever" on your forehead, does that prove that you are really clever ? And if a company takes a red box, writes "Fuzz Face&quo...

Re: Dunlop - Band of Gypsys Fuzz Face Mini FFM6

Great Pedal! I love it. Cleans up real nice when you roll down the volume. Quite different from other Fuzz Face pedals being based off the Octavio circuit minus the octave. BC108's for transistors. Sounds best with a stack. What are you vomitting about ? Too much dope today ? There is not a single ...

Thanks for the nice pictures. The only still unanswered question is: what is written on that brown ceramic capacitor beside the two diodes ?

I like those japanese engineers. Obviously in 1976 they were even able to clone something which didn't exist.
