Not so many FAQs, but more QUOs; "questions unasked often"! 

Do I need to buy an instrument before starting lessons?

You will need something to practice on from day one.
An amplifier is not essential to start, but should be considered within the first year.
Contact me when you are ready to book lessons.

Am I ready for a full-size instrument?

Full-size basses have a 34" scale length, that is, the vibrating length of the strings.
Short scale basses of 30" are much kinder to small hands.
Taller beginners should seek out a wider bodied bass for better control of the playing position.

At what age could anyone start playing bass?

I currently have no bass pupils less than 11 years old.
I have seen 25" scale basses, based on the size of a guitar,and though I have no experience of these for teaching, they sounded pretty good.
My only concern is that bass guitar is still a very physical instrument, simply because of the thick strings.
Even these tiny basses need thick strings to make low notes, and I suspect little fingers cannot easily control them.
I would recommend that younger enthusiasts start on guitar.
