Bass bow works wonderfully with my Ibanez EUB, feels mobile on the strings and takes the rosin well.
Unfortunately mine came with a minor, hopefully cosmetic? manufacturing fault (the plastic coating on the metal winding is twisted, and there is what is probably rusting under it). Coruss have not responded to several emails over a few weeks, so I'm very disappointed by the service level and will be investigating which is the correct EU body to raise a complaint with.
Apologies for the inconvenience you faced. We're so sorry for not receiving your previous emails. You can send it back to firstname.lastname@example.org.
Regarding the bass bow issue, it's actually oxidation due to the silver-plated copper. While it shouldn't impact performance of our bow, we understand your disappointment. We're keen on setting things right. If you need, you can send the bow back. We'll inspect and repair it pronto.
Your satisfaction is our priority, and we're committed to making this a positive experience for you.
