hey guys,
I finished a pinnacle, and it sounds pretty good. As I never had a real pinnacle, I'm not sure how close it sounds to the real deal. That being said, I got the voltage measurements from my Q1-Q6 and some of them are close to the real pedal, and some seem further off.
So...here are my voltages vs what is on the real wampler. I only have trimmers for Q5 and Q6. When I first trimmed the pedal, I noticed I was using a 9.6v power supply, I retested the voltages but didn't retrim Q6 yet, as it looks off and I can fix it with the trimmer.
Do you think I'm close enough on Q1-Q4? If not, anything short of trimmers I can do?
Here's Wampler's...
Drain / Gate
Q1 4.72 / 0
Q2 8.98 / 2.99
Q3 4.78 / 0
Q4 8.98 / 2.99
Q5 3.59 / -1.68
Q6 3.86 / 0
Here's mine.
Drain / Gate
Q1 5.14 /0
Q2 8.94/2.98
Q3 5.06/0
Q4 8.94/2.98
Q5 4.06/.04
Q6 3.35/0
Any thoughts/recommendations? Thanks in advance!
Oh, and for kicks and since I have the data in front of me, here is the voltages I got when I was using the 9.6v psu.
Q1 5.42 /0
Q2 9.49/3.17
Q3 5.53/0
Q4 9.49/3.16
Q5 1.10/0
Q6 2.8/0
What layout did you use? Any sound clips, pics etc..? Your voltages look alright to me but I would judge it by the sound. You can try to compare it with youtube videos if they are good quality and there are tons of them. Like I say.. if it sounds good, then it is good!

Hey man, I ended up using the vero from tagboard effects. After hearing people having problems with the jfets, I was preparing myself for a long road of troubleshooting after the build. By some miracle, it fired up on the first try. It sounds pretty good, but I wonder if it could sound better. From the youtube vids I heard, it seems pretty close, but it's hard to know for sure, ya know?
I guess I just wasn't sure how close the voltages had to be to be considered "good". .1? .5? I have no clue.
I tried changing the Q5 an Q6 trimmers around and I'm not quite sure what the effect each does, but it does seem that one of them, Q6, I think makes the bass loose and flubby if it's too far off spec. Thanks for the response man, I appreciate it.
