Don't Forget

Carbon/maple hybrid delivers the warmth of wood and clarity of graphite.

Designed by Ned Steinberger himself, the Steinberger Synapse XS-15FPA 5-String Bass Guitar features the unique U-channel graphite core in a rock maple neck and maple body. Combo head accommodates double-ball and single-ball strings while the unique direct-drive double ball bridge adds super-fast string changes and tune-it-once tuning stability.

While other guitar manufacturers have been resting on their laurels, Steinberger's been thinking. Witness the strap hook, recessed tool holder and output jack, fold-down leg rest, and phenolic fingerboard that's slick as butter and fast as lightning.

Low-impedance EMG USA bass pickup with internal low-impedance preamp and piezo bridge extends the range on both ends for earth-moving lows and phenomenal transients from slap-style playing.

Includes gig bag.

  • Cybrosonic Technology featuring an integrated graphite U-channel combined with a three-piece hard maple neck
  • Maple wings
  • Phenolic fingerboard
  • EMG USA humbucker
  • Piezo bridge
  • Ebony saddle
  • Direct-drive double-ball bridge
  • Fold-down leg rest
  • Recessed tool holder
  • Recessed output jack
  • Strap hook
  • Combo headpiece

Comments about Steinberger Synapse XS-15FPA 5-String Bass Guitar:

man i really wanted to not return this bass. i liked its design but it was not made well enough.
although i have tried other bass's made in korea that were nice; but this needs a good truss
rod system. quality control should have not let that problem pass.
I think it has a great design and great features that all would want and include
great feel. sound, controls, pickup, balance.
low quality rating due to poor truss rod. this is a basic must have and has to be quality to
be dependable and always usable. this bass a poor quality adjust nut. it was stripped out
on arrival.
low value due to unusable truss rod. what have you got when this is gone.
i have read other reviews else where that mention this issue.

Couldn't be more pleased

By Bass Dude-5glrB

Comments about Steinberger Synapse XS-15FPA 5-String Bass Guitar:

I was a little hesitant at first to buy a Steinberger as they were expensive and different than what I was used to. After seeing the affordable "B" models I decided to give it a try and buy a white Synapse. After receiving the bass I was not quite sure what to do with it. Yes, it was different, felt different and sounded different. But after getting used to it I was blown away. Outstanding quality with an array of sounds (EQ) that far surpasses any of my other 20+ basses. More treble and more bass than anything else that I have ever owned. The Piezo pickup really adds a twang that I have not experienced before although it makes the bass "squeak" when touched on the body as the entire bass becomes "active", only noticable when everything else is quiet and only if you move around (no big deal). Whether using your fingers or a pick, it will take a while to get used to as the feel is different lacking the part of the body where normally your wrist or thumb rests. Give it time and you will get past that. The neck feels great and "normal". I don't even miss the headstock, it is just the right hand that needs to get used to the new bass. I love it. I just bought an additional black "B" model as well as a fretless red "B" model as well. Don't be afraid of the "Bs" as they look brand crispy new to me. Certainly no wear or defects, only a "2nd" stamped under the leg rest that cannot be seen unless the leg rest is extended and you look right at it. This won't be my only bass that I use, but it will certainly be one of the few that I make a priority when it comes time to grab a bass or two for a live gig. Gig bag is nice and tight as well. If you don't mind something a little different than the norm, give this bass a try. I'm sure glad that I did. If you can't afford one of these then try a much cheaper Hohner Steinberger copy. I highly recommend those as well, above the also affordable but lessor quality Steinberger Spirit models.

Great bass! :)

Comments about Steinberger Synapse XS-15FPA 5-String Bass Guitar:

I really like this bass. It sounds great tonally and it have a decent low B string for being only 35" scale. I do not see the same amount of love and care that was put into the build of my Japanese Fender P-bass though. Other than that is is a great bass.

Synapse 5 string bass


from Brooklyn, NY

Comments about Steinberger Synapse XS-15FPA 5-String Bass Guitar:

The only thing I really don't like about my new bass is, that you can not adjust the hight and intonation of individual strings. The reason for this is, that the saddle is one solid piece. Only course adjustment is possible.One other thing is, that even though my nails are short, they make little marks on the body of the instrument when I pop strings. Naturally the nails will hit the body slightely when bringing the finger under the string before pulling up for popping. Other basses have a finish that can take this abuse, only after a long time will you see marks.Other then that, I really love it. Sounds great, looks great, feels great.

Comments about Steinberger Synapse XS-15FPA 5-String Bass Guitar:

I brought this bass. For me I was looking for a similar experience of their earlier Ls and XLs. Was a bit of a gap from them other models.
In the short time I've owned it I've found tuning a little tested in hot temperatures. I've used it on my travels in hot climates in the north west of Australia. They don't like the heat and I was constantly checking tuning. Might be due to no truss rod as someone mentioned above.
I found and didn't know before that it was an EMG P bass pick up in there. I did not like it one bit so I swapped out the pick up which originally is a EMG 40P for an EMG 40DC. Sounds great and more to my liking after being on musicman and fender jazz basses. Personal preference there in sound choice.
I think the E string has a distorted type sound in it when struck. Not sure if it's this one in particular or others but it's noticeable and not good. I've used in studio and live situations.
It's not all negative lol
With emgs solderless easy to connect pick ups it's made it easy to try a couple different pickups. The sound is big.
The sustain on it is the longest I've heard. Takes a little getting used to compared to a standard bass both in how it sits on you and positioning of the fretboard. Little adjustments but good once you're away.

I didn't like the issues I had with it and more so number one problem.. its sound. Since swapping pickups and an outlook on trying others thanks to EMGs easy to install capabilities I'm liking it.
So it stays in the family.
It was to be sold but now a keeper.
