5 band groinal filter
Audiobomber's 5-band groinal filter
Mastering is a very time consuming undertaking und due to the workload, cultural background or personal preferences, changing of attire is not always possible or desirable.

This often leaves the sound engineer with no other option than to perform necessary grooming tasks with true vintage gear that generations of mastering engineers have used before - like the 'manual 5-band groinal comb filter'.

The 5-band groinal comb-filter may not be an entirely hygienic device, but its impact on mastering is althemore soothing and relaxing, often bringing the sweetest overtones to the final master.
