PA-STK1n Parallel Axis Review by Hames J

Well-known member
Since I can't find ANY in depth reviews about this particular pickup I'd thought I would do the honours for y'all after installing one just a few hours ago.

My guitar is a MIJ Jackson PS-4L that features an alder body, maple neck, rosewood fingerboard, 24 frets, licenced floyd rose tremelo and a HSH pickup configuration.

In the middle position a SVR-1 Vintage Rails has found it's residence for over 2 years now seeing two pickup changes either side of the fence in it's time. Initially it's neighbours were an SH-6 bridge and PAF pro neck. Recently a PA-TB2 Distortion Trembucker and SH-2n Jazz moved in.

While the SVR-1 is a warm pickup, it could never for the life of itself keep anywhere near up with the output of all the humbuckers I've put next to it. It also didn't exactly have that funky single-coil vibe, a void I've been looking to fill in my guitar tone for awhile now.

Enter the PA-STK1n. Saw one on Ebay last week and decided to snap it up as they are so hard to come across and looked like it would be a great companion to the Parallel Axis Distortion in the bridge.

Not sure if I was using correct wiring for the Parallel Stack as it has 5 wires instead of the 3 the SVR-1n has, I figured out a way to copy the old middle position wiring pickup config. Although diagrams on the SD homepage schematic section (which really need diagrams for HSH guitars) suggest that the green and ground wire should be attached to the volume pot, I copied the previous config that my tech used to originally to install the SVR-1 over two years ago, where he attached the white wire (for the PA-STK1n's case, the green and ground wire) to the tone pot in the same solder patch as the resistor.

Plugging my guitar into my Laney AOR amp, the high-gain channel was already activated. The first thing I noticed was how incredibly hot this pickup is. Felt like a real humbucker in the middle position but still retaining some that jangely vibe. Under so much gain and saturation you can still hear it's pseudo single coil personality. You can almost use this a heavy rhythm pickup or for playing screaming solos. It certainly has balls to spare and shows no sign of laggin' behind in output volume compared to the humbucker positions on this axe.

Tight bass, twangy mids and highs topped off with a generous dose of compressed dynamics. It ain't hard to get this pickup giving your sound A LOT of slap & tickle.

Switching over to the normal amp channel where all the mid gain stuff happens, the PA-STK1n in the notch positions helps better prepare you for some classic rocking or texas heat situations.

Plugging into the low sensitivity input on the Laney where all the cleans are found, the Parallel Stack shows it's true qwirky colours in all of it's glory. If Billy Madison played through this pickup he would say "why that's QUACKTASTIC!". All those clear as bell and funky tones are here in spades. Bold and upfront, it makes no qualms about being in your face if you just dig into your technique slightly. With my Vintage Rails I had to REALLY dig to get the same vibe.

Due to it's ceramic magnet I guess it would be preceived as quite a "sterile" sound to some who are used to playing low output alnico true single coil pickups. I certainly didn't have trouble getting warm tones out of it but I could understand how some may be turned off by it's non-sutble dynamics.

Quite amazing how I could switch through all 5 positions and pretty much perceive no significant volume change at all. Heck it's giving the SH-2n Jazz a damn good run for it's money and it doesn't even sound intimidated at all by it's mean cousin the PA-TB2 which alone has monstrous output.

I recommend the PA-STKn to anyone with a floyd equipped guitar with a HSH or HS pickup configuration. It will really make you want to utilise your middle and notch positions for those pokey strat tones you don't normally achieve on such guitars without having to adjust your master volume. My guitar now is much more versatile.

I only need a PA-TB1n for the neck position to give my guitar the full Parallel Axis make over. In the future I also hope to try out the PA-TB1 Original Parallel Axis and PA-TB3 Blues Saraceno.

On that note, I must also point a slightly odd phenomenon after installing the PA-STK1. For some reason, the PA-TB2 and SH-2n that were already in my guitar are now sounding BETTER than before. More open, sweeter tone and longer sustaining. I kind of suspect might it have something to do with the different wiring the Parallel Axis Stack uses over the Vintage Rails that was in there before.

Thanks for the review. I had been wondering about this pickup for a while.

What was it listed under? Marital aids? I've been watching eBay for one for months!
 
Re: PA-STK1n Parallel Axis Review by Hames J

I put two in a guitar simply because I had a PATB Distortion and I wanted the guitar to look matched. I was shocked at how professional and high grade they sounded. They're really a players pickup. They're very tactile and sensitive, vs. the way you have to fight vintage singles for the tone. So they allow you to play for the sake of dynamics without dictating that you play a certain way in order to be heard, or in order to get a specific tonal quality.

I don't want to give anyone the wrong impression, I use vintage singles most of the time anyways. But these feel almost like you've got an active boost in the signal. Not because they're overly hot, but because the notes jump off the strings with a little more excitement. I recommend them highly to anyone that isn't married to all the vintage strat characteristics. (good and bad)

Also most of the time when someone says a single coil deviates from "vintage strat" sounds, they're making excuses for the single coil lacking clarity and definition in the top end. They're saying it's warmer, or darker, or just plain duller. This is not the case with the PATB Stack. It's actually more excited and crisp, while still delivering good single coil warmth and depth.
 
Re: PA-STK1n Parallel Axis Review by Hames J

Nice review. I'm installing PATB-1 (neck) and PATB-3 (bridge). The middle will either be PA-STK1 or STK-S4.

After reading your review, I'm leaning toward the PA-STK1.

Are you running 250k or 500k pots?
 
Re: PA-STK1n Parallel Axis Review by Hames J

Hehe, I've actually taken it out of my Jackson and got the stock pickup back in there. I used it with 500K pots. I'm not playing that guitar anymore and will probably sell it soon.

I've seen the PA-STK1n described as having more of a P-90 vibe and looking back I would have agree.

I decided to resurrect this thread, enjoy the youtube demo 9 years after.

 
Re: PA-STK1n Parallel Axis Review by Hames J

Definitely going to take one home after seeing that video.

I guess it helps to work at SD. On my side I am having a hard time finding where to find online on sites like GC, SW, MF. I cant find it in my usual distributor website here in Mexico.
 
Re: PA-STK1n Parallel Axis Review by Hames J

I bet a lot of the liveliness of the pickup is due to the twin parallel pole pieces instead of standard slugs.
 
Re: PA-STK1n Parallel Axis Review by Hames J

I managed to snag one off ebay a few months ago... It's waiting for the rest of the acquisitions for the right project. :P
 
Re: PA-STK1n Parallel Axis Review by Hames J

Thanks for sharing the video!

I'll be putting a set of these in my HSH RG.
 
Re: PA-STK1n Parallel Axis Review by Hames J

Nice to hear a good demo of it. I'm thinking about one of these to match the PATBs in an HSH Floydcaster. I have a Quarter Pound there now (which I love, and which has remained in place for over 30 years) but there's another guitar that wants it now. My decision is between this STK or another QP. I'm leaning toward this one for the sake of noise canceling, and secondarily to match the the look of the others.

I wish he had switched to the regular Strat pickup just once for the sake of comparison. But by all reports the STK is a very hot pickup, I guess the level difference would've rendered the contrast pretty useless. I'd love to hear a comparison with the QP, which has some girth to the tone and is as loud as many humbuckers but still retains a lot of the singlecoil vibe. I noticed he mentions the STK is like that too...

Guess I'll have to pick one up and post my own impressions. They're pretty hard to find used. New ones are more widely available now; not many of the big places used to stock them. And since there aren't a bunch of used ones on Ebay I assume people are keeping 'em. A good sign, I think.
 
Re: PA-STK1n Parallel Axis Review by Hames J

I wish they made a bridge version. A complete set of these might be killer in my Peavey T-30. It already has the square-ish cutouts and the wide string spacing.

Btw, this isn't my actual axe. Just one like it from someone who has better photography skills than me.

I bet it would be hot enough for the bridge position. If you were using three you'd want to lower the others a bit, but it sounds as if you'd still get still get enough juice from them.

Would love to find one of these used. I know I'm not the only one looking.
 
Re: PA-STK1n Parallel Axis Review by Hames J

^^ I looked at the beta version of the new website and sorted all the single coils by output, this one was more output than the STK-S6 which is a bridge pickup so I think it makes sense to try it in that position.
 
Re: PA-STK1n Parallel Axis Review by Hames J

Wish you could get em in colors.. would def get either the patb1 or 2 for my charvel
