The schematic is still not correct!!!!
The 1uf electrolytics may well be non polar types - i just wish someone would post some decent pictures of this pedal
None of the photos show the hidden resistors or the potentiometer wiring correctly
Anyway the 1uf capacitor connected to the base of the 2N5088( or whatever this transistor is )is shown shorted out in super velcro's schems.
It should be connected in parallel with the 10k resistor also connected to the base - of this I am certain - check my rough drawing earlier in this thread
How sure are you that the input resistor in the voltage divider is 100k and not 1M as I speculated have you measured it's resistance - what are the colour codes on the resistor body
none of the photos posted so far show this resistor clearly - 100k seems a bit low
It appears that the 2N5088 (or whatever) is used to mute the output of the effect unit. When the footswitch is closed the led indicator is energised the base of the transistor is grounded through the parallel 10k and 1uf capacitor, and is therefore turned off - this creates a high impedance path from collector to emitter and unmutes the tone control at the output of the distortion stage. The relay is of course energised as well, and switches the true bypass switches on the input and output to engage the effect. ( I drew this incorrectly in my rough sketch
)
Of course when the footswitch contacts are open the led indicator turns off, the transistor is biased on and creates a low impedance path between the collector and emiitter of the NPN transistor -this effectively shorts the tone control to ground and mutes any leakage from the high gain distortion from getting into the clean bypassed signal - the relay contacts change to the true bypass condition.
An advantage of this switching technique is you only require a single pole single throw (SPST) latching footswitch. A disadvantage is the extra DPDT relay required to perform the true bypass switching.
