    I have ordered a new jazz bass a few days ago and there are two controlers, the bass/trable and the passive mode where is written -15Bb, +15Bb and -18Bb ,+18Bb. Whats that???

    I'm pretty sure it's dB and describes the cut/boost range

    I believe those should read -15dB, +15 dB and -18dB, +18dB. dB indicating decibel, a measurement of (audio) level and the amount of boost and/ or cut. That would be my guess based on your post. A link to where you saw that might be helpful if further explanation is needed.

    You probably mean dB, which stands for decibels. Read about those here:

    What is a decibel, and how is it measured?

    It's the abbreviation for decibel, a unit used to measure audio loudness and also the 'strength' of electronic audio signals referenced to a standard level, "0 dB".

    The correct spelling for the abbreviation is :dB Yes, lower-case d (for "deci", meaning "a tenth of") and capital B for "Bell" as in Alexander Graham Bell, inventor of the telephone.

    Other electrical units are named in honor of the pioneer researchers and scientists of electricity, including:

    Volts - named after Allessandro Volta
    Amps - named after Georges Ampere
    Ohms - named after George Simon Ohm
    Watts - named after steam engine inventor/improver James Watt
    Farads - named after Michael Faraday

    Please capitalize these unit names and their abbreviations if you're a spelling/grammar stickler like me. Just like we write "Fender bass" and not "fender bass". :thumbsup:

    millivolts = mV
    milliamps = mA
    Kilo ohms = K Ohms
    microfarads = µF
  6. Bb is A#.

    @Crater thank you for pointing this out. I noticed this after posting and thought about editing the post, but thought "meh". I updated my post now.

    Curiously, the "bel" is spelled with lowercase b, though the decibel abbreviation is dB.

    I'll suggest that The Dyslexic Decibels could be a band name.

    A sharp retort? No, that's not a bass that had the tort removed and reinstalled. Wait a minute...

    That's for when plain old vanilla diminished or augmented voicings are just not enough. I mean it is a jazz bass, it's to be expected.
