Dunlop 105Q Trimpot... S!!!!

[Sir Edward V]

Alright, before you jump on me : I know the main trimpot everyone talks about is the one that they use to adjust the delay time for the wah turning off. I assume that is the brown one... But I just got mine in the mail like an hour ago and took it apart to check things out on the inside, and I saw two more white trimpots in the top right corner... thing is, they had little blobs of hot glue holding them in place...

Now the correct train of thought: hmm, they probably have those there for a reason, I shouldn't mess with them.

My train of thought: hmmm, I wonder what they control... I should mess with them to figure out what they do.

So before I go and ruin my perfectly good, paid $26 for pedal, does anyone know what they control?

I tried a search and people only talk about the one for delay time

If you cannot resist the urge to futz, make sure you mark the current position of the pots so you can hopefully get close to the original settings again!

Sorry, don't know, I'd just be googling for the answer.

yeah, I did this with my guitarist's Phase 90, I even marked the spot, but later he noticed a difference... he didn't even know I messed with it

he was mad for a while until i helped him fix it...

I also e-mailed dunlop the question... in my experience they are very helpful with these things

I asked them something about the blowtorch I owned for a little while and the CS rep didn't know the answer but tried pretty hard to get it for me... and he did

[Sir Edward V]

oh yeah, and it isn't exactly a "switchless wah" there is a momentary switch that gets hit whenever the pedal is all the way toe up, then when you start to wah, it isn't being pressed and your signal gets affected

Qwestion is, what do they do?

that was the point of my post, I want someone to answer that question for me...

Where's your sense of adventure? Tweak the durned things.

[dragon5363]

Be sure to report back with your findings. well be waiting for the de-brief.

[Sir Edward V]

dammit, I didn't want to be the guinea pig...

I guess I'll let you guys know... ::sigh::

[syciprider]

Remember, Edison, Bell, Ford and Co. all went where no one has ever gone before on their way to greatness.















Hey, can I get your other pedals if you fry yourself?

[vegas532]

My understanding is that they are there to regulate the internal voltage to the circuit board...I wouldn't mess with it.

I don't like Edison. He also nixed the telephone greeting "Ahoy-hoy"

Not if you change the resistor in charge of the momentary lapse.
Did it to mine, and there is no lapse AT ALL - absolutely instant on/off with contact. Love it!
I'm not sure which resistor it was....#25 maybe?
Talk to dunlop about it - they can tell ya.

[niftydog]

Ooo... you hit a nerve there, syciprider!

Not only that, but he patented other peoples ideas before they could, stole other ideas from his employees and when he couldn't do either of those, he actively and deceitfully suppressed inventions that he knew were better than his.

He paid poor children to catch stray animals so he could electrocute them in public in order to further his business ventures. What a lovely guy he was, and how deserving he is of our admiration... not.

His selfish greed prevented Tesla from obtaining just recognition for his world-changing invention - the AC generator.

I'm stopping there before I get banned...


Besides, you should strive to fail more spectacularly, like Tesla did. When something of his went "out of order" the whole town knew about it the instant it happened!

mine is the same... and i was so stupid enough to mess with the pots and hoping the delay to get away, and didn't mark the position spot.... now i got a klicking sound when i rock my pedal.... so could someone kindly post a picture of the original setting please?

no, I'm not talking about a lapse of any sort, I am talking about the physical switch that gets pressed

I know how to fix the time lapse between switching

I actually like the pedal with a bit of time delay

hmmm... maybe I won't mess with them...

[Sir Edward V]

oh right almost forgot about this:

message from Dunlop:

Hello Nathan,

You are correct about the glue being there to prevent the trimpots from being moved. They are set here at the factory and any deviation from where they are currently set will drastically decrease the sound quality of the effect. I would strongly suggest that you overcome the urge to rotate them because it will be next to impossible to reset them correctly by ear.

Thank you, please let me know if you have any further questions



and yes, my name is Nathan

[Zeemno]

Interesting, I opened mine and don't see any glue inside the trimpots. The one near the jack seems to be connect to the hot pot, the other to Q pot. If I had an accurate Multimeter, I'd mesure their values first and then did some twaeking!

From top to bottom on mine: 9:30 ; 9:00 ; 11:45. But it rather sounds like your hot pot needs cleaning.

Hope this helps.

Did you find out what they were actually for?
There was also glue on the trimpot inside my Phase90
