The JSX is pretty bad ass,………

JSX combo about 300 miles from me, i ruled it out cuz i don't wanna spend 3 hrs in my car.

HaHa, my bad man. The gist of what was done was mainly to tighten up the low end, and make the amp a bit more open/less compressed. it has a very focused attack now. The presence and resonance controls have a greater affect on the amp really allowing for extra tone shaping. My JSX will also run 6550 tubes now. The sound to me is modded Marshall meets boosted Rectifier. it has these Snarling mids, but with a Modern Feel and attack, Punchy and in your face.

That sound pretty bad ass. Did the mid frequencies shift?
While I like it in a mix, the mid focus on a lot of Peavey amps sat in a place I didn't like overall. For me, the JSX sat right on that line

On mine, the Mid focus shifted a little. The cocked wah sound is gone. To my ears the mids have a more upper mid thing going on after the mods, that is definitely more musical for sure. The EQ controls in general have far more effect than they did, allowing for unlimited tone shaping

One of my favorites for sure. I've been doing a bunch of research on Peavey amps lately. The jsx has a couple revisions and the XXX II has a couple differences of its own.

If you hate the active tone controls, the valvekings have almost the exact same preamp with a more typical FMV passive tone control. It's a bit funny how many amps have a similar DNA yet prices are all over the map.

I read somewhere that the vk’s are basically 800’s…. Way closer than the Windsors were….

I was always under the impression that the VK was a cheaper asian-made version of the Prowler

The VK 1x12 combo and Prowler share basically the exact same panel layout so I guess it would make sense

The peavey rockmaster/ultra lineage of amps really are a great tone with a fairly low price point. I've had my old rockmaster preamp for over twenty years. It is insanely picky about power amps but with the right one, it sounds great. For the $35 I paid for it in 2005, I've definitely gotten my money's worth out of it.

The JSX might be one of the best amps I have ever heard for someone who plays primarily lead guitar. Voiced for that singing lead tone. You don't see nearly as many JSX in the wild anymore. The JSX and XXX are super similar schematic wise. Very small component level changes for the most part. For the most part if I remember correctly the gain pot in the crunch channel and a plate resistor on the lead channel were the biggest changes, with few other adjustments here and there.

The JSX is in my top 5 favorite amps. I've owned 3 or 4, always loved it.

Here is a question about the JSX if someone has owned both the head and the combo …. Has anyone with the head hear the honkiness? Or is it something inherent with the combo? Or visa versa ? Or both. Could speaker type affect this tone. ? I own the head (now twice) and I don’t hear it as a bothersome tone. But I also don’t do high gain music more 70-80s so maybe I’m wanting to hear a bit of mid as that’s what I hear in my head.

Hey stranger! Hope you've been well my dear friend.

The JSX head is definitely a bit honky to my ears, especially paired with V30's IMO.

My first experience with one was at Sam Ash when I went to buy my Apollo interface and was waiting for the sales guy to find it in the back warehouse. To keep occupied I plugged into a used JSX into a Marshall 1960 cab and was very surprised how awesome it sounded. Super bouncy and easy to play, pinch harmonics jumped and screamed, high end was sweet like a modded Marshall. I ended up taking it home with me that night as well.

Fast forward to playing it through my cab collection at the time and it had a very inherent mid honk that was next to impossible to dial out, especially with V30's. More so than GB's strangely enough.

So IME, yes...the head is very mid heavy.

Pretty good sounding amp especially with the 6L6's.

Built like shit though, lots of crappy components.

Good to hear from you; hope all is well. That’s good info. I’m using my ADA 2x12s and it sounds killer. I hope to record some this weekend and see if the mid comes through. I have other cabs as well to fiddle with as well, V30s and others. Will prob look at the Marshall with 65s vs the EVH cab We shall see.

I have a JSX with some tweaks I did to it. At the time I had Kyle @ KSR helping me with ideas. It's actually the one amp I have kept through everything, and I've owned a TON of amps as most of us older cats on this page have . Lean, Mean and Aggressive

You have the best jsx i’ve heard no doubt
