ScottR Posted January 23, 2017 Author Report Share Posted January 23, 2017 Thanks Scott! I'll have to get back to you on the measurements but I can tell you they are not the same as that single-cut I did with P-90s a few years ago. Same 25"scale, but the single-cut is 22 frets and this is 23. And I purposely moved the bridge pickup further away from the bridge--roughly where the pole on the low E string is on a tele bridge. I wanted the bridge pickup to play a little warmer than normal. And that works quite well btw. And if you pick below that pickup, it sounds like a normally placed bridge pickup, and there is plenty of room to do just that. The P-90s on the single-cut were built by RAD and these are Klein high wind P-90s. The single cut used 500K pots and this one uses 250K pots. So while both guitars sound unmistakenly like P-90s, they have distinctly different tones. SR Quote Link to comment Share on other sites More sharing options...

Thinking about replacing it gave me another question for you Andrew. What would happen if I replaced the volume pot with a 500K and left the tone pot at 250K?

curtisa Posted January 23, 2017 Report Share Posted January 23, 2017 Overall sound will be a bit brighter and a tad hotter than it would have been with a 250k volume pot installed. Quote Link to comment Share on other sites More sharing options...
ScottR Posted January 23, 2017 Author Report Share Posted January 23, 2017 So both the volume and tone pots don't both have to be 500K for that to happen? I went with the 250K to get the warmer sound, and figured both pots needed to be the same value. I've never heard of anyone mixing values. What would be the result of a 250K volume with a 500K tone pot? Sr Quote Link to comment Share on other sites More sharing options...
curtisa Posted January 23, 2017 Report Share Posted January 23, 2017 Probably not much discernible difference with everything at full tilt compared to vol = 500k, tone = 250k. The feel of the tone pot may change slightly. My gut feel is that mixing of values isn't done because then manufacturers would need to stock two sets of pots. It's cheaper to buy 1 million pots of a single value than it is to buy 500000 of two values. You can always slug a bigger pot to behave as a smaller pot. A 500K fixed resistor strapped across the middle lug and ground of a 500k volume pot will limit its maximum resistance to 250k (and make the taper slightly more logarithmic, which may be advantageous). 2 Quote Link to comment Share on other sites More sharing options...
curtisa Posted January 23, 2017 Report Share Posted January 23, 2017 Of course, you could go all out and really stagger the differences between the two pots. The pot with the lower value will cross-load the higher value pot, darkening the sound with everything flat out. Say 500k volume and 100k tone. With tone at 0 you'd still end up with the same amount of treble loss as it would be with a 500k tone at zero, but with tone at 10 it would be like the tone pot was only partway up... ...maybe not so useful?

ScottR Posted January 23, 2017 Author Report Share Posted January 23, 2017 So using a 100k tone with a 500k volume, would be similar sounding to using a 500k tone with a much smaller cap on it? You guys that actually know what's going on with electronics are just like magicians! I feel like I know just enough to know where not to stick my bare finger.

Bigger cap = more treble loss (strictly speaking, the point at which the treble loss commences as you wind the tone pot down becomes lower in frequency). Smaller value tone pot = duller sound at maximum setting (the tone pot becomes less effective at "opening up" the original sound of the guitar when at maximum). 1 hour ago, ScottR said: You guys that actually know what's going on with electronics are just like magicians!

Prostheta Posted January 24, 2017 Report Share Posted January 24, 2017 This aspect is the only reason why I think active pickups limit choice. Reducing impedances fundamentally alters that relationship between the controls and the pickups. We'll discuss this more when I announce this season's video builds and start discussing spec refinements. Nina's SG will be a simple 500k log for both volume and tone with a 22nF or 33nF cap. I'll probably tune the volume a little too make the roll-off sweeter, but I need to buy her a little valve amp first to analyse the relationship.

I mean- look at the curves and the set of p-90s on that baby. ooof! nice job Scotty- if I didnt mention it in (years) previous- I really dig the head stock design too- especially the personalized volute. too cool. curious- what are the measurements on the center of the p-90s to the bridge? and- is it the same scale and pick up location as on the guitar you did a couple years back that you put up the mp3 soundbites of ? So, I took measurements from the poles to the front of the bridge: neck....5.5", bridge....2.125" SR Quote Link to comment Share on other sites More sharing options...

Andyjr1515 Posted January 26, 2017 Report Share Posted January 26, 2017 I get distracted for a few days and look what's happened. I am in complete awe just how good this is, Scott.

ScottR Posted January 26, 2017 Author Report Share Posted January 26, 2017 Cheers Andy! I appreciate the kind words. I showed it off yesterday to a couple of guys that have been following it on line. They both commented that it was sleeker and smaller bodied than it looked in the pics. I never picked up on that.....because I'm rather familiar with its actually size, oddly enough. I don't know if it is camera angles, focal lengths or just the shape itself that gave the impression of more size. SR Quote Link to comment Share on other sites More sharing options...
