Description
Anyone who’s tried to dial in relief on an acoustic bass through that tiny sound hole knows the struggle — blind reach, awkward angles, and a wrench that never quite seats right. The CruzTools GTAW4 is built specifically to solve that problem. The 4mm ball-end tip finds the nut even when you can’t see it dead-on, so you’re not fumbling around trying to line things up by feel alone.
Both segments of the blade are extended beyond what you’d get with a standard hex key, giving you the reach to get past the soundhole opening and actually seat on the nut deep inside the body. Once you’re there, the oversized handle gives you real leverage and control — small, incremental truss rod turns matter, and this tool lets you feel exactly how much you’re moving without overtorquing.
This is professional-grade gear, the kind techs keep in their gig bag for setups on the fly. If your acoustic bass or acoustic guitar’s neck is fighting you — too much bow, too much back-bow, buzzing frets that come and go with humidity — this wrench gets you in there to make the correction yourself instead of waiting on a shop appointment.
