The cover of the instrument will not be markedly damaged during the installation. The physical appearance of 
the  vintage  instrument remains nearly the same as before the installation. If necessary, the interface can be 
simply removed and the instrument restored back to original appearance. 

All original circuits of the Vermona Synthesizer remain without any modification. The instrument can be used 
the same way as before the retrofitting.
