What is a Bb

[Daniel125]

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

 

[filmtex]

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?

I'm pretty sure it's Db

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".

millivolts = mV
milliamps = mA
Kilo ohms = K Ohms
microfarads = µF

Bb is A#.

A sharp what?

@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 what?

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

Bb
It's a Bed and Mini-Breakfast.

I take offense, being a founding member of MADD (Dyslexics against mad mothers).

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.
