Your voltages are reasonable, maybe Pin 2 could be a little higher byt shouldn't be too much of an issue. Could you check voltages at transistors?
Also, check the continuity with the switch, is everything connecting where it should be when the switch is engaged/disengaged?

[hahafender]

2 transistors from left to right

9.27         9.30
2.74         2.75
3.26         3.28

as far as i can tell (not much) the switch has everything connected. maybe i dont know much on how to see what should be connected or what not. the circuit, to my understanding, seems good. so im debating on changing the switch

[tjdracz]

Wait, is it CBE left to right? What transistors did you use? The voltages at B and E seem to be backwards...
Did you possibly use something like 2sc1815 without swapping the leads (they are ECB, similar to many other Japanese types)?

[hahafender]

they're 2n3904

C    C
B    B
E    E

like that

[tjdracz]

Then something is seriously amiss there. Base should be close to 3v and emitter at 2.5 or so. The way it's now, it's right strange!

[hahafender]

as per the schematic here...

how odd... this circuit has been flawless for two weeks, and all of a sudden it gets messed up when this guy takes it home and plugs it in!?

[tjdracz]

Ok, disregard all I've said. Voltages do seem fine, forgot the trannies are just buffers.
It's down to switch and all offboard wiring probably then, really hard to say as all voltages do seem good so it should be working fine IMO

[inefficiency]

If it was fine til he plugged it in, maybe you should ask him to tell you about the power supply.

Is it a possibility that maybe he plugged in the wrong type of PSU and fried the chip or something?

[hahafender]

he told me it was 9v.. so idk. the other board (morning glory) works perfectly fine... that's the weird thing. and all voltages for the chip seem good. so maybe its a bad switch. im not sure. wiring should be good. resoldered everything, and again... it did work perfectly fine. so ill swap the switch tomorrow. i really dont get how this happened

[inefficiency]

It is definitely a bummer. They pick their moments to stop working....

To test the switch just set your multimeter to continuity, check from one pole to the one is should be switching to and then click the switch in and test it to the other one. Do this for all 3 sets.

I might not be speaking the right jargon there, but you get what I mean.

[hahafender]

just got a chance... switch looks to be switching perfectly. very strange... maybe its the 3pdt toggle switch? all those lugs are continuous... is that normal for the specific wiring i have done to it? as per this schematic:

[hahafender]

okay... interesting thought here. when both sides are off... the center lugs on the two 3pdt switches have continuity. when i turn on the morning glory... they still have continuity... when i turn one the 808, there's no more continuity. im assuming this is why it goes completely silent when engaging that side at any time... any thoughts?

[hahafender]

the same is true on the toggle switch. once 808 is engage, continuity is broken between the two lugs connecting to their two respective 3pdt switches. (i dont know how they're numbered lol)

[hahafender]

im beginning to think it's the 3pdt toggle switch that's faulty... i had some problems with it on my initial build... it cut out when it pointed towards the morning glory until i took it out, and put it back, and it was fine. weird. but i think that toggle has some problems. what do you think?

[tjdracz]

Looks like something dodgy might be going there. These switches are stupidly sensitive to heat, there's a chance you might have fried it when soldering. Even if that's not the case, they are often massive pain and fail quite often

[boratto]

Shake the end of every wire with the effect turned 0n... if it starts to make sounds again can be a poor contact.

[hahafender]

shook all the wires... no sign of any signal whatsoever :/

[hahafender]

which do you think it is? the switch or the toggle?
