Hey there. So... I am im a bit of a pickle. I bought an Epiphone Thunderbird 4 string last year. Around march if i remember correctly. Anyways, the action is horribly high. Im only now getting around to it, as i was a fairly new bassist back then, so i had no clue about all of this "action" buisness. Here i am now, though. So, i took it to my local music go round. I asked for a truss rod adjustment, and for the action to be lowered. They told me to pick it up the next day. Well, they did not do a thing to the bass. The neck was still bowed as ever, action still horrible. What is the best plan of action, taking it to a Schmidtt Music and pay about 20 bucks plus price of strings (im currently broke ) or could i do it myself? If myself, how do i do this?
