Sonor OrffBT BasisTrolley Universal Orff Instrument Stand Adapters Ac2 Chromatic Adapter - Deep Bass
Independent shopping perspective
The Korena take
The Ac2 chromatic adapter in deep bass size, for mounting chromatic bars on a Sonor Orff BasisTrolley stand. Buy it to extend gear you already own.
Strong match
Who this is for
- Adding sharps and flats to a deep bass instrument on a BasisTrolley
- Programs already standardized on Sonor Orff stands
- Keeping chromatic bars mounted rather than loose in storage
Consider the trade-offs
When to look elsewhere
- Anyone without a BasisTrolley stand already in the room
- Soprano, alto, or tenor instruments, which need a different size
- Buyers expecting the chromatic bars themselves
What matters in use
The specifications, translated
Catalog numbers tell only part of the story. These are the details most likely to change how this product feels, sounds, or fits into a setup.
Detail 02
Chromatic adapter
Holds the add-on sharp and flat bars in playing position rather than requiring you to swap bars manually.
Detail 03
BasisTrolley system
Designed around Sonor Orff's own stand. Third-party or older stands are unlikely to line up.
Detail 04
Hardware, not an instrument
This is a mounting part. It makes no sound and adds no notes on its own.
Final check
Know before you order
- 01Chromatic bars are not included. This holds them; it does not supply them.
- 02Confirm you have the BasisTrolley stand, not a different Sonor Orff frame.
- 03Verify your instrument is deep bass. Sizes are not interchangeable across the range.
Product questions
Before you decide
Straight answers to the questions shoppers most often ask about this product.
01Does this come with chromatic bars?
No. It is the adapter that mounts them. You need the chromatic bar set for your deep bass instrument separately.
02Will this fit my alto or soprano instrument?
No. This is the deep bass version. Smaller instruments in the range take a differently sized adapter.
03Do I need the BasisTrolley stand for this to work?
Yes. It is built as part of that system, so check the stand you own before ordering.
04What does a chromatic adapter actually do?
It positions the sharp and flat bars alongside the natural bars, so a player can reach the full chromatic set without stopping to swap bars.
