Introducing Thrash Factor!

Re: Introducing Thrash Factor!

I have a newer stock JB (TB-4) and an older SH-4 that I put an RCUOA5 into. I notice differences between them, but each suits the guitars that they're in. Another variant? Yay!

In this case, the JB we pulled from Dave's guitar that was used as the basis for Thrash Factor was not factory spec - that is to say that a standard production JB from the 90's should sound the same as a modern production JB, but the one we are replicating did not.

Cool man, do you have a pic of the original unicorn pickup base plate and all? Would be groovy to see what the real McCoy looks like.

C'mon Riley, you gotta give us more than that. What makes Dave's old JB different and why is this one anything more than a hotter JB? As a consumer of all things JB related, I am totally down to try one out (assuming I can get it without writing on top), but there is little "magic" left in pickup recipes.

actually I took a look at the specs sheet, the Thrash Factor has a dcr of 16.4kΩ while the JB has a dcr of16.6kΩ, assuming they wound it in a similar pattern, this should correspond to a higher resonant peak because of the lower inductance with a slightly LOWER output assuming the magnet is the same, I am guessing also the mids response would be different with a greater emphasis of the high mids and less low mids. In other words, harsher, airier, slightly tighter.

I don't know. But another metal comparison would be great anyway, this time including PATB and other new models (duality, Mustaine's JB etc.)!

The JB from Dave’s guitar had a lower DCR and higher resonant peak than normal. Without giving too much away I will just say that there are more factors when winding a pickup than just wire gauge and number of turns that can affect the sound of the finished product, and we’ve made some changes to the process for Thrash Factor that help it replicate Dave’s pickup.

The natural harmonics and cutting bite in RIP are some of the best I've ever heard. I think his solos on that album should be remastered. Marty's solos can clearly be heard but Dave's solos are lost in the mix especially his solos in Holy Wars.

That’s only a difference of 200 ohms, temperature alone can affect that nevermind tolerances of the materials used. If there is a difference, doubt it’s just that.

you are right that 200 ohms may not be much, but a drop of 200ohms also comes with a drop in inductance, which I mentioned

I put in an order for a couple of bridge models (reg and trem spaced), so we will see.

It wouldn’t be a large enough drop to radically affect the resonance frequency. Dont assume the slight drop in dcr is due to a reduction in turns. keep in mind slight differences in material tolerances will more than affect that.
 
Re: Introducing Thrash Factor!

As for how dave looks... it's called 'aging'. Leave him alone.

As for the JB that Dave had in that particular guitar, I suspect it was an older JBJ type. I've owned several JBs and JBJ's and the latter DO sound different. Just enough to matter. Maybe Dave's was a little more toppy than some. Variance happens.

If you want that old JBJ sound, go buy an Antiquity JB or if you want a further refined take on that sound, the Demartini model is excellent.

As for the Thrash Factor, tighter lows and less mids are cool but the more agressive highs is something I DON'T want from a JB. That being said, I'll be interested to see how these compare against JBJs and current JBs.
