I am looking for a set up that works well for practicing (headphones). This setup will be in an apartment where "boom" is definitely an issue. Am I wiser to buy a low watt practice amp and use headphones, or can I get a efect unit that i can paly directly into. I have a Zoom 500 something, but frankly, I just dont like the "thin" sound it gives my bass. I have read a lot of the negatives regarding multi-effects...so what do I need to do here? Thanks for your help!!!
