Is it a set up problem?

[Arnold Schnitzer]

I was scrolling through the forum and noticed that your question had not been discussed. So here's my input:

I'd like to know what you mean by "the pizz sound is not so good". Does this mean there is a lack of bottom? Too boomy? No sustain? Too much sustain? Unfortunately, words like "good" are not specific enough. Please give us more to go on, and perhaps we can advise you. I realize English may not be your first language, but give it a try.

Pics of the bass would be helpful too. Flatback or Round? String length?
