Maybe:

in: %1[%2-%3]

out: %1'['%2']'

How to make this action for batch processing?

For sure set Mp3tag Filter to ...  
"%_FILENAME%" MATCHES "^(.+?_[.+?)-.+?(])$"

... then apply "Convert Tag - Tag" ...  
... or Action "Format value" ...  
Field: \_FILENAME  
Formatstring: $regexp(%_FILENAME%,'^(.+?_[.+?)-.+?(])$','$1$2')

... or ...  
in case of the trailing sequence has always the same length, ...  
then apply "Convert Tag - Tag" ...  
... or Action "Format value" ...  
Field: \_FILENAME  
Formatstring: $cutRight(%\_FILENAME%,8)']'

Big thanks, **DetlevD**!

Field: \_FILENAME  
Formatstring: $regexp(%_FILENAME%,'^(.+?_[.+?)-.+?(])$','$1$2')

works fine!

How add whitespace character in your formatstring?

i have mixed files... for example:

Jay\_Mexx\_-_Plastic_(Original\_Mix)\_[Deep\_Records-DRS245]

Jay Frog - Dream (Original Mix) [Groove Records-GR054]

etc...
