Peavey: JSX Joe Satriani Signature Head

Purchased from: N/A

Sound — 10
I've ran a few guitars into this amp, including an Epiphone Les Paul Standard Plus, a PRS Custom 22, and an Ibanez RG1570. With the noise gate activated, the amp is almost silent. It is extremely versatile, which is the amps strongest quality. The cleans are modelled after the Peavey Classic 50, and are crystal clear. The clean channel also takes pedals extremely well. The Crunch channel is nice, but has a little bit too much gain for crunch. I was able to get a nice metallica tone on this channel, and also found that it has a fuller tone than the Ultra channel. With the 'fat' switch engaged, the tone gets a boost in bottom end, and also has the mids boosted. This causes the amp to take on a darker voicing, which is great for playing british rock, etc. The Ultra channel is pretty thin, which is great for shredding. It also has more gain than the Crunch channel. With the 'fat' switch engaged, the channel loses it's thin sound, and takes on more of a conventional lead tone. All in all, the sound of the JSX is great.

Overall Impression — 10
The JSX makes a great first impression, and the good news is, that that impression lasts. It's great for almost any style of music (I play blues, metal, pregressive rock, classic rock, and virtuoso and it suites me great). If you're in the market for an all-tube half-stack, and you want something with great tone and a ton of versatility, then the JSX is deffineately worth a look.

Reliability & Durability — 9
This amp is very dependable, and is well built. I'd deffinately trust it to gig with.

Features — 9
The JSX features 3 channels, clan, crunch and ultra (lead). It has channel switching and an effects loop, along with a built-in noise gate. It is 120 watts, all-tube, and has more power than you'd ever need for conventional gigs. It features a 'fat' switch on both of the distortion channel.

    I have the JSX and its great..but really it doesn't sound that great at low volumes to whoever said that above. When you crank it, that's when you get the great tone. Also, I'm kinda bummed theres no reverb. The good thing is this amp takes effects very well.
    yeah, im saving up for this head after the holidays, tried it at guitar center, and it sounds sick for the type of music i play.
    metal Lover
    Also, the JSX can sound different than other JSXs. I've tried one that could get very distorted on the crunch channel but mine sounds classic rock ACDC type distortion on the crunch channel. Make sure you play the exact amp before you buy it.
    ya i tryed this and the 6505 out at guitar center today, the jsx sounded incredible at a low volume, while the 6505 would barly distort at low. once i save enough im going to get the jsx combo.
    im getting this amp next weekend, i can't wait!! Ive been trying out all the amps i could find over the last few weeks and the JSX has beaten them all in every way. Great clean tone, nice crunchy bluesy channel (not that i will really use it) and my favourite, the Ultra channel...best metal tone i have found of any amp so far! (Ive played all the major marshalls, 6505, mesa stiletto, a couple of engls). Three great channels, versatility and features to boot, awesome look, and reasonable price when compared to others of same level.

    Dude i tried the 6505 before trying this and the JSX was way more impressive. The 6505 needs to be loud (and i mean LOUD!!!) before it starts to sound good (but does sound very nice once its up there) while the JSX sounds awesome at lower volumes and only gets better when u crank it up.
    HOLY LOWDNESS JOE! I just bought this head for $730 used. I use a peavey valveking cab with it and it sounds great. I personally love the clean channel the most. I love the master volume on it. To get a super clean sound turn the cahnnel volume as low as it goes and the master up. Do the opposite for a more distinct clean sound. Very versatile. Definatley recomend this thing!
    The combo for this amp is incredible. If I only had $1600....
    anyone played the new JSX 50 head? is it as good? A 100 watt head is probably too much for my garage.
    i've been seein these heads on ebay for very cheap. hope to get my hands on one =)
    Like Dr. No said, it's gotta be cranked at least a little bit to get a real smooth distortion out of it. Low volumes are still good, but just not quite the same. Really, though, when you're in your bedroom or you can't turn up your amp, you need to just take that into consideration if your tone is off--it's like that for many amps. If I could change one thing on this amp it would be to make the clean channel a bit brighter. However, I have found out that if you have a higher input level going in (say, use the high input or a clean boost pedal set to 4-5 dB) it comes through with a lot nicer of a punch The Mids are fantastic on this amp, and to get satriani's sound you just need to keep a flat EQ and play with the gain. The resonance/presence knobs are quite responsive. All around great amp. Perfect for someone who's into an "articulate high gain" amp with a nice amount of chug on the thick strings. Very versatile. Does most styles justice. The clean is also much better with effects. Slap some delay in there. Yum
