Thanks for the clarification!No, nothing to do with the size. If Biyang makes (or probably more likely made) a big box equivalent of the Fuzz Star, it would probably have the exact same linear taper volume pot.
This is more just along the lines of keeping costs down and simplifying construction, so basically something like the Fuzz Star has three linear taper 100K pots in it. That simplifies component inventory, and makes it more foolproof WRT getting the right taper & value pot in the right spot on the PCB.
The truth be told, even ProCo used three 100K log taper pots, which is probably why the filter control is wired in reverse, because the sweep works better that way. For ProCo to get the traditional/intuitive effect would have meant using a reverse-log pot.
Also, some original EHX Big Muffs had either linear or log 100K pots, I guess really depending on whatever could be sourced in large quantities. Seeing something like a linear pot for the tone control (which is a must) and then a log taper pot for the vol. control is actually more typically found with either some DIY kits, or some of the more spendy boutique Muff variants.
All of this said, components at the 'recovery' gain stage (after the tone circuit) can be modified, to increase/decrease the amount of recovery gain (which is probably the right way, design-wise, to get the vol. knob to end up at a theoretical 12:00 position). Oftentimes, all that has to be done is to make that transistor's emitter resistor a bit larger, if a linear taper pot is being used.
...But in the case of the Fuzz Star specifically, I can understand why Biyang wouldn't go to any kind of custom alterations like this. And as far as swapping resistors go, they're SMD, so not really an option for the casual DIY'er, either.
I'm fairly certain that the Mouse, Brownie, and Max Distortion all have a log taper vol. pot, so it might be possible to get a part number off of it, and then it's just a matter of sourcing it from somewhere. I'd guess that the same pots that Biyang are using are mass produced for other electronics, so something should be available. Probably the only other potential snag I might think that would be encountered is that these specific pots use a solid 'D' shaft, to be used in conjunction with a setscrew knob (it's a little less common).
Will just deal with Fuzz Star as is ( we both have our weaknesses!), and figure out how to work it in- plus doing that in a band ( volume) context will help- won't need to be so dang sensitive about the Volume
for those who are not TDPRI long timers, I have an old history of bugging the hell out of 11 Gauge, about Blues Drivers vs. OD-3's, Rats, Tube Screamers, Fuzz Faces, OCD's, Timmy vs
Very patient and informative- I try to retain the basic sound/operating info; will never actually understand electricity or electronics.
Thanks, 11 Gauge!
