1 rhcole 6 months ago I recently became the proud owner of an '04 6120 Jr2. My first Junior! Love it. As I like to do, I took a pair of headphones, plugged into a clean pedal, and compared the Jr's sound with other guitars I own. The Filter'Trons on the Jr are smoother than I expected, as I used to own a 6122 from the same era that had a bit of "ice picky" treble that caused me to replace its pickups with TV Classics. Not this Jr guitar.Now, each tonal comparison between guitars I own made sense to me until I put the Jr up next to my Power Jet. I reasonably expected the PJ with it's PowerTrons to sound darker with less treble than the 6120. I also expected the PJ to display a distinct midrange bump by comparison.Nope. While the Jr. had a stronger high Midrange/lower Treble, let's say peaking somewhere around 5-6kHz, the PJ actually had a slightly brighter high end at around 6k+. I didn't hear a noticeable midrange bump in the PJ like I expected either. Furthermore, in many other respects, the Jr's and PJ's pickups sounded similar.Now, this was just how both guitars sounded to ME, no measurements involved. And I was also trying to ignore the more solid PJ body sound vs. the hollow and airy Jr. Still, it made me wonder, because I was expecting a pretty distinct difference between the two pickup sets, and I wasn't hearing it.It made me wonder whether the differences in the bodies were influencing the tonal responses more than I expected, ie: would the Jr. sound way darker if it had PowerTrons in it? Would the PJ brighten up noticeably with the Filter'Trons?I went online and tried to find more info about those '04 Filter'Trons, but couldn't come up with anything useful. I REMEMBER my 6122' FTs from that era, they were quite bright, almost too much so.Well, I was just surprised, and I thought maybe one of you experts could explain what might have been going on, if only to suggest that my aging ears are not quite as accurate as they used to be.What do you think?
