we pulled one out of dumpster in jersy once. still worked but none of us ever saw a BNC before so we stuck it in my friends garage. its still there.

if you do her you have to change your sig to "has sex with old ladies for oscilloscopes"

Also, oscilloscopes need sometimes need to be calibrated so that one might not be in perfect working order
That's as far as my knowledge on scopes goes

its not so much a big deal if your not taking measurements or watching two waveforms together. the amplitude may not be what you think it is but who cares, its all relative. the main goal hear with pedals is to see wavefolding and PWM fuzz squares changing duty cycle. you can do half ass frequency response tests too with your eyes and a guitar. thats all that matters.

right...anyways about that flipping 2n2222 business.

Holy crap i let this thread slide to page 4???? how long have i been gone???

so sorry dude.... will this pic help you any?

Image

the TP/ND circuit is the one on the far right.... sorry i really can't get a better pic, this pedal is loaded with wires... but you can see how i took the 4pdt toggle switch and separated two on one side and two on the other, then put the Emitter and Collector of each tranny in one of each leaving the base leg up in the air because a wire will connect directly to that one....

make sure both trannies are facing the same direction when you solder them to the lugs.....

THEN, you take two small wires and solder them to the the same lugs you soldered the Emitter and Collector legs to leaving the other end of the wire loose and away from the other lugs....

Get your three wires from the board (connected to the emitter/base/collector holes where the original transistor lived) and connect them to the corresponding CENTER lugs on the switch (Emitter leg of the tranny to the emitter hole on the board, etc) and the BASE wire will connect directly to the BASE leg that's still free (see the wire with the black heat shrink? that's the base wire).... get those in place because the next step is a bit tricky...

the small wires that are soldered to the emitter and collector lugs at the bottom now need to be soldered diagonally to the opposite lug in a criss cross pattern to the remaining top lugs.... and you're done.....

confused??? yup, i'm a douche.... :picard:

Thanks so much!~ :D YES finally...though I will have to read this a few times and draft it out on paper I'm sure I will be able to get this.
In other news I just got accepted to University of Idaho's College of Engineering!~ I should mention that UoI's flagship major is Electrical Engineering :cool:

No that's Idaho State I think...unless even though the colors are Yellow and black they like blue fields.
