The Engineer’s Thumb is a unique compressor that picks up the classic OTA type of compressor and gives it some modern adjustment. Most notably, it’s has a much quieter noise floor, and it’s also less coloured than the classic Ross/Dyna type of compressor. This compressor is great to use with Acoustic, Electric and Bass guitars.
