Formerly called “ESP Standard”, all ESP E-II instruments are created at our ESP factory in Tokyo, Japan, and are designed for professional players who accept no compromises in tone, feel, or reliability for their guitars and basses. The new BTL Series basses (available in the 4-string BTL-4 and the 5-string BTL-5) offers a set of extraordinarily flexible tools for sculpting the perfect tones for any genre of music. Available in an outstanding Black Natural Burst finish over an alder body with spalted maple top, the BTL basses offer a sonic signature powered by an Seymour Duncan SSB passive pickup set that’s paired with ESP’s own high-end active 3-band Cinnamon EQ system. The extraordinary versatility of the bass’s controls (volume with push-pull preamp bypass as well as balance and discrete controls for bass, midrange, and treble frequencies) allows you to use this bass for any gig, in any style. High-end component include ESP strap locks, Gotoh tuners, a Hipshot A style bridge, and a bone nut. Includes ESP hardshell form-fitting case.

I recently aquired my 2018 used E-II BTL-4 from a seller in Japan and it's a fine instrument. The only problem I've found is there doesn't seem to be an owner's manual available on ESP's website. The manual that is available seems to be pretty generic and covers all their guitars and basses, but it's dated 2009. The card in the case is all in Japanese, not surprisingly, but it would've helped if it was also in English. The EQ seems to be the opposite from my Ibanez basses so I keep turning the wrong control at the moment. This could be awkward if I need to switch basses during a gig. 

I'm also getting a bit of noise from the volume pot when turning up and down and a few sprays of contact cleaner hasn't solved the issue. This is disappointing for a supposedly high quality instrument and it might need a visit to my local guitar tech to look at it. 


Playing her for three months. Can't believe how superior she is compared to other bass in the same price range. Just wanted to say thanks.

Is this the bass that niilo sevanan from insomnium uses?

Carl N.

Hey Devin, I can't speak for all of his instruments but I know he has one of those.



Looks great! What is the weight? How is the balance with straplock near the bridge in the center of the body? Have you considered moving it up slightly so the guitar naturally stays at a 2:00pm position?

Todd B. ESP

Hi, The average weight is 8lbs. The balance is excellent with the long upper horn. No need to move the button on the body when you have a long horn up top.
