musictheory.net provides the ability to make custom web exercises to practice music theory topics. I have created several buttons below for custom exercises for BASS players. Please be aware that you will need these exact links to get the exact exercises you need.
The amplifier (or amp modeler) is the second most important part of your guitar tone besides your guitar itself. The following is a guide to how to get the best sound from your gear.
I like flatwound strings for 1 reason only: the feel. I like that they are slippery, and they are not as abrasive on the fingers as roundwound strings are. I don't have this problem with roundwound guitar strings because the windings are so small that the grooves in the strings are almost unnoticeable to me, but when I play roundwound bass strings, I feel that they quickly hurt my right hand fingers if I play aggressively.
That being said, I wish I liked roundwound strings. The natural brightness of the strings can come in handy, especially for high gain tones. With my roundwound strings, I find myself having to boost treble quite a bit on any gain tone to get the same sense of cut and attack.
So why do I stick with roundwounds? I find myself playing lower gain genres of music on bass, and I save the high gain sounds for guitar. I think roundwounds sound good for jazz especially. If I need brightness, I play with a bright sounding pick instead of fingers and that usually helps.
Ask yourself these questions to help you choose the string for you:
Do I want a bright, cutting tone, or a dark, mellow tone?
What genres will I be playing?
How much gain do I need?
Fingerstyle vs pick?
Is your right hand ok with the roughness of roudwounds?
I think most players will find roundwound strings the way to go, especially if you play with a pick most of the time. It is much easier to darken brighter strings than it is to brighten darker strings. It's a close call for me, but the feel really is the deal breaker. I want to be able to play fingerstyle for a long time, just like for guitar, so that is enough for me to choose flatwounds.
For guitar players, the best speakers for live use are either 10" or 12", with 12" being the most popular choice by a large margin. Bass players are a bit more split between 10" and 15". 12" and 18" speakers for bass can be found in use, but I'm not a huge fan of these. I think every player can find the tone they are looking for in 10" or 15" speakers. If you are looking for a brighter tone, try 10", and 15" for darker tone.
