I ma looking for a bass for beginers but that can be used for the next 10 years. Is it beter to have 4 of 5 strings and what bass do you recommend for a cheap price. I have an amplifier. I will be used for Metallica still playing. Does it mater if the bass is made for jazz or metall? I can buy a tenson deluxe J5 for 180 euro. What do you think? Thank you very much.
