Krivo Pickup Quick GuideKrivo Pick-Ups is a small, homegrown company building handmade pickups in the USA (Portland, Oregon).

The Krivo pickup for upright bass now mounts on most ANY bass with a heavy duty but lightweight brass L-bracket (no modification to bass is required: bracket attaches with included 3M™ Dual-Lock adhesive-backed fastener). The new mounting system enables the Krivo to fit even basses with a very thin or even curved "cutaway" style fingerboards. The new mount keeps the pickup securely attached even with very forceful and aggressive playing—great for rockabilly and psychobilly players. Of course, it still includes our bonus items (like our jack mounting kit.)

Includes our exclusive Gollihur Music tipsheet to get the most out of your purchaseThe Krivo humbucking bass pickup is a very good alternative to piezo-based pickups for players who play in high-volume situations, or who have stage setups that are particularly susceptible to feedback problems. A magnetic pickup is largely unaffected by the sort of vibration that causes "rumbling" or "humming" feedback with piezo pickups, and also doesn't pick up sound out of the air, so it doesn't suffer from the "screeching" feedback that microphones often do.

Krivo has developed (and continued to refine) this pickup over the last several years, and improvements have made it sound "woodier" and less electric, as well as silenced the noise levels and electrical hum. In 2017, the pickup's size and weight was greatly reduced, and in 2016, major improvements to noise specs were introduced. We've carried the Krivo since 2010, and at that time it had been updated with a special combination of ceramic and neodymium magnets for clarity, warmth, and higher output than other magnetic upright bass pickups. It also uses easily adjustable (hex wrench) pole pieces to easily achieve even string response. And the current pickup is virtually noise-free.

Since it's a magnetic pickup, no external preamp is needed, since most (pretty much all) bass amps are designed to accept magnetic pickup input with no additional "buffering" needed. A preamp certainly could be used, if only to provide useful tone-shaping - and a handy volume control on/near the bass - but it certainly isn't required.

The drawback (usually) for magnetic pickups is that they usually sound more "electric" since they are getting their signal directly from the strings; they're not really putting the wood (and resonant cavity) of your upright into the sonic equation. However, Krivo has taken steps to provide a more woody, fat tone from the pickup. It uses wooden casing parts, custom "scatterwound" coils, and what Krivo calls "Optimized Microphonics."

What the heck are "Optimized Microphonics"?

For most magnetic pickups (for electric guitar or bass), "microphonic" isn't usually a good thing. It was more common in the old days - if something inside the pickup was free to vibrate (like windings that are a little loose), and was attached to the magnets in the pickup, it could vibrate in concert with sound waves that hit it. Because of this, on some old basses and guitars, you can shout into a pickup and actually hear your voice faintly through the amp, as if through a microphone - hence the name.

Nowadays, most pickups are fully "potted" (soaked/filled with epoxy, wax, or some other material) to prevent this sort of thing. However, Krivo - based on extensive "trial and error" development - specially hand-winds each coil with a controlled variation of both fused and loose windings. Each individual coil is then hand "sealed" (rather than soaked or potted) in a special mixture. Krivo thereby uses controlled microphonics to actually encourage a certain amount of this electro-acoustic effect, which (I can only assume) is what creates a less "sterile" or "electric" element to the sound.

These features, and the pickup's overall design, all combine to create a tone that is less "electric" and a good bit more "organic" than one would expect from a magnetic pickup.

Side benefit: It also provides a bit more sound from the fingerboard, meaning that rockabilly slap players will even get a bit more of the fingerboard "click" sound that so many of them are after. And if you couple this pickup with a fingerboard transducer, your sound will really begin to click!

The big, round sound from the Krivo pickup can work particularly well for slapstyle, rockabilly, bluegrass, Latin music, and modern jazz. It's not the most natural sound you can get with a pickup, but it could possibly be the most natural sound you can get with a magnetic pickup.

IMPORTANT!! Please Note:

Polepiece spacing on the pickup is approximately 15/16" from center to center. This allows for variances for use on 3/4, 4/4 and most 1/2 size basses. If your spacing at the bottom of the fingerboard is wider, you can adjust the depth of the pickup and raise the polepieces to compensate (such as on a 4/4 bass.) For a 1/2 size bass, it is important to measure to ensure that the strings will be adequately captured by the polepieces.

Magnetic pickups require strings with a significant magnetic content in order to provide a good quality signal. Not all metal is magnetic - many strings use nickel or other alloys, which are not magnetic. Double bass strings can contain a number of different non-magnetic materials, unlike bass guitar strings that are intended for use with magnetic pickups. Therefore, it is important that you consider that factor when choosing strings for use with this or any other magnetic pickup.

Many strings are quite suitable, such as Thomastik Spirocores, Corelli 370, etc., but others and mixes of different manufacturer or model strings may result in uneven tone and response. For instance, Pirastro Obligatos may look like metal strings, but they are primarily a nylon core, with only a very thin metallic surface -- as a result their response is not satisfactory due to the lack of metal. You may wish to research the matter or inquire with the manufacturer as to string construction or survey other bassists who are using magnetic pickups to ensure that the strings are suitable.

The recommendations below are from other players using magnetic pickups, not necessarily my personal experiences.

Strings reported to be GOOD for magnetic pickup use:

  • Eurosonics
  • Pirastro Original Flexocore
  • Thomastik Spirocores, Superflexible
  • Corelli 370 (I can vouch for these)
  • Innovation Polychrome (work but with lowered output)
  • D'Addario Zyex (work but with lowered output)
  • Jargar dolce
  • D'Addario Helicore-- (Note: though I have my concerns with the E string; seems as if its response is somewhat lower than the other strings, at least the Orchestra and Hybrids I tried seemed that way.)

Strings reported to be NOT GOOD for magnetic pickup use:

  • Pirastro Obligatos and Evah Pirazzi (minimal metallic content)
  • LaBella Supernils (no metallic content)
  • All Innovation Strings (no metallic content)
  • Gut strings (insufficent or no metallic content)

    Krivo Pickup

    Posted by Jim Faris on Apr 4th 2024

    I'm still feeling my way with it, but it doesnt sound like a P-bass... and that's great! I've mostly been a gut string player, but I dont slap as much these days, and I'm playing bigger and louder shows, and not always with my amp/rig. So, on Mark/Bob's great advice I bought some Corelli 370 bass strings and I ordered a Krivo. Wow! it's a great pick up. In the past I've had other Mag pick-ups, but they all make my bass sound like a P-Bass. Not the Krivo. I'm guessing it has to do with the level of microphonics that it produces, not much, just enough to give it a bit of a more natural, almost microphone-like sound. The mount is solid and stays in place even when I do the occasional slapping. Easy to install and set up. This past week I had a rehearsal for a loud rock show, had to use the house amp, didnt bring a preamp. Plugged in, dialed in my sound and got on with it. There are a few issues and solutions. My fingerboard is much more flat than average, I mean over a 1/4 less than most. so upon mounting the Krivo, either the E or the G side of the pick-up was so far back that the volume level was very uneven. Solution: the Krivo has adjustable pole pieces, I set it where the A and D sound good, adjusted them down a bit, then raised the G and E until I had an even sound. Issue #2: the barrel on the output jack is so smooth, there is no amount of tightening that will keep it in place while plugging in/out. Easy solution, wrap a small rubber band around the barrel, no more slip. This pick-up is amazing, simple, effective, powerful. It gives my bass all the flexibility of an electric but keeps my tone.

    It might be the best thing I have ever purchased for my bass sound.

    Posted by Mica Calfee on Jan 26th 2024

    I have used several different types of pickups over the years. When a friend showed me this pickup, on his bass, I instantly knew I had to have one. After I easily installed it, I showed my wife, (who is also a Jazz musician.) She was amazed. Her words were, “Wow! I can see why you wanted that!” (It is always good to hear the wife say that after you spend $100s on a new "toy".) I experimented with the ability to do long glissandos, and hammers, and lifts. They were so strong and clear. Then I tried some Rockabilly slaps. (I never do that, partly because it always sounds like crap on my bass.) Now I need to find a Rockabilly band to join. As I experimented more with the great sound, my wife said, “Do you know you are giggling?” She was right. It might be the best thing I have ever purchased for my bass sound. It makes my somewhat inexpensive “student” model bass sound like it cost $1000s more.

    OMG What a difference maker!!

    Posted by Daniel Ketterer on Sep 29th 2023

    I was getting frustrated with feedback issues when I amplified my Bass. Nothing I tried seemed to help. Last week I ordered one of these pickups because it looked like the answer I was after. Man oh man was it ever!! I now have richer tone and more low end oomph than ever and I can play loud, if needed, and there's no feedback at all. Service was awesome. I ordered on a Wednesday and they came Saturday by noon. I'm a very happy camper and so are my bandmates.

    Posted by Matthew Thomas on Jun 26th 2023

    I have been looking for a pickup that doesn’t feed back and this is it. Nice warm tone, even when using a bow.
