Exactly. 1894 have trialled a drum and a megaphone. The drum in particular was divisive amongst fans, with one fan who was on the drum for the first half of the Gladbach game in 2016 copping shit loads of abuse on the concourse at half-time. As for the megaphone, it took years of dialogue with the club to even get to the point that one was allowed to be used.
Funnily enough, the drum did help to contribute to the atmosphere a fair bit that night but the amount of negative comments meant that it was never going to become a regular thing. For the record, I'm not massively in favour of a drum myself but the point was politely made at the time that if more fans could actually be arsed singing then we'd never have needed to trial a drum in the first place.
