Excellent, Road worthy case for a very nice price

Von-Funkenstein 15.02.2026

I would have given this five stars all the way down, except there's no compartment/retaining system for the power supply for the synth.
Construction is excellent though, i've always used either semi, or full flight cases, semi are generally ply wood instead of the resin/plastic used in this, and full flight are ply covered in aluminium sheeting too.
Although they're obviously not as strong as a full flight case, (i'd be happy to stand on a full flight case and jump up and down on it, i wouldn't do that with this one though) i'd say they're almost as good and certainly as good as a semi flight, but lighter in weight.
All riveting and extrusions are high quality and very well-fitted, internal padding is adequate, the handle and handle attachment points feel like they're up to the job too.
This is a really good case for the money!
Just get some Velcro, glue it to the inside and use it to strap the power supply for the synth in too, it would be great if Thomann had thought of this though.
