What are these Bass Guitar controls for?

[alexwaston]

Hello everyone!

Ever since I received my Behringer BDI21 am modeler, I've been playing around with my cheap bass guitar.

I'm not really a bass player, so if I may ask... what are the knobs for? Mine has 3 and I know that one is for the volume.

 

 

It is a Lyon 5-string.

 

Relax more: watch fantasy movies | watch adult movies | watch jason bourne movies. Good fun!

If only one is a volume control, then the other two are probably tone controls. It seems odd that you have no pickup selector switch (or do you?).

 

If correct it means that the volume knob is a 'master' control, meaning that it works for both pickups together.

 

The other two would almost certainly be independent tone controls; one for each pickup. The bridge pickup (angled one close to the bridge) will have a brighter tone, whilst the neck pickup will have a lower 'bass-like' tone. If you have no pickup selector switch, that means that both pickups are always on together.

 

Try out the other two knobs to see what tone changes you can get.
