topic = question..

you can, but that's a waste of a nice pot, trim's are alot cheaper, but for temporary it should work.

well you see, the trim pot was for internal tweaking, and then after it says i can make it an adjustable external pot, but it doesn't say what to use.

here goto the bottom of this page:

look at the adjustable and the adjustable - external pot entries. I want to do the external one. Should i use a 100 K trimpot or a 100 K pot

There's no difference. He states in the article to use a pot mounted on the side of the pedal.

You don't want a visit from the circuit police do you!

One thing to watch out for is not trying to use a trimpot for the wrong application. In other words, don't try using a cheap RadioShack trimpot for a guitar amp bias control or something. It will get fried because it wasn't designed for that kind of current across it...  :shock:
On most 9V to 12V guitar effects circuits, you can substitute one for another with no problem. I use a trimpot where it is something that I want to adjust once and never mess with it again.

ah, ok. Thank you everybody.

i ran out< and used a hundred k pot with the wired leading to clips...used as a trimpot...setting Jfet's biases one by one and measiuring the undisturbed setting of the pot that got 1/2v on the Jfet drian...substituting fixed resistors for each jfets bias needs.
