In the words of Seinfeld, "I think I may have made a big mistake." Decided to mod my bass myself to accommodate thicker strings. Went from steel strings to weedwackers. Used a pocket knife to add a little room to the notches on the bridge and used my DeWalt cordless and small drill bits to open up the tailpiece slots. Left the nut alone. Didn't have rasp files to do any of this work. As you might guess, this work did not come out pretty. Strings are installed and seem okay although E is a little buzzy. Are the slots in the tailpiece required to follow the curvature of the fingerboard? I think when i bored them out i may not have stayed true to their original angles. Is it a big deal if the notches in the bridge are not smooth and rounded(some are kind of a v shape now? Also, some may be more than half the diameter of their respective string. Should I take it into a luthier and get things tweaked to a higher level of quality? Does it really matter? I'm new to the upright bass so any advice is appreciated. This is not a troll post. I really was that impatient/frugal the other night. Thanks for any help!
