I went into Jaycar last weekend, and while the guy who served me was (trying to be) most helpful, he threw so many different alternatives at me that it confused me more than helped. Went in asking for something specific and he went round in circles trying to get me to use everything except what I asked for! I'm now back to sticking with the tutorial and will just ask for what's on the list, no variations from what I want. Now I am just doing the research on what I want
I'm pretty sure it's the 5k trimpot. That much I can sort out on the spot by opening up the kit in store. It's the log/linear thing that I'm not sure about.
