Title: Questions Re Naughty Fish
Post by: Terrapin on May 17, 2016, 08:56:05 PM
I'm thinking about buying the Naughtyfish board, but have a couple of questions about parts. First, are the pots linear, log, or reverse-log? Second, I've got some on-on-on switches that are different in the center position than the smallbear switches. Can I use these by just switching wires around to the board, or must the switches work identically to smallbear's for the build to work?

Thanks in advance!

A=Log B=Linear C=reverse Log and yep, you need an On/ on/on and an on/on They don't necessarily have to be from SB but that's the idea. That's an awesome build.

Thanks man, and good to hear it's a great pedal. The problem re the pots is the BOM does not indicate whether the pots are A, B, or C. http://madbeanpedals.com/projects/NaughtyFish/NaughtyFish2015.pdf

If you look carefully 1MC is reverse log and the other two have a b after the value indicating linear.

Got you -- thanks! I naturally think kilobytes for kb and basically just didn't see it as "K space b" rather than "k!"

One more question (sorry to keep bothering you). Where have you guys found LT1054 chips or, if they are too hard to find, what's a good substitute for this chip? I don't see them at Smallbear or Tayda.

There is no substitute for the LT1054, they cost a few dollars too.
I would think Small Bear has them, maybe under voltage regulators or something.

Many thanks Jules. When I searched for LT1054 at smallbear it returned "Your search for 'lt1054' did not match any products." Note to self that smallbear's search engine does not match the stems of queries!

No worries mate, I thought it was a bit weird it didn't come up in a search too.
