The tuning machine for the D string of my Thomann student double-bass came apart after many years of hard work. The Roth and Junius replacement looked identical to the original on the website and indeed, it was an exact fit and my bass is back in playing order. An easy DiY job.
I also have the Markbass Micromark 801 combo amp, the Shadow SH SB2 double bass pickups and the Gewa Prestige Bass Gig Bag all of which I am well-pleased with.
