Hello^^
Thank you for your answer!
Its a large Djembe...the diameter is about 33-34 cm
My hands are 17,5 cm long... my friends might be a litte longer, let them be 18 cm (she has longer fingers)
Unfortunately we can´t tell how old the skin is. It might be old. It´s at least 1,5 years old (drum was sitting at her boyfreinds house) plus the time the former owner had it on.
I would say the tones sound uninspiring and the slaps sound a little metallic, but really only a little, bass is good. Other Djembes including my old axe sound far more metallic.
Well so we´ll try cranking the drum a bit and see if that helps... and if the skin pops, we at least have a very good reason to try a new skin

Thanks and have a good day
