They really give you the same "rich tube" warmness as some of the multi thousand dollar Universal Audio compressors. Also comes with original ONTOP 12v power source. Fantastic mic pre - very clean and present, no blemishes or scratches! Super on vocals and also stunning on bass. Smooth world-class optical compressor is fantastic on bass and vocals. Also great on anything with strings, and makes hand percussion sound very realistic. Read the reviews - it's a killer preamp. This is my second tampa, i sold my first tampa to my buddy a couple of months ago and decided to get another one. Ive owned this pre for about a month now and its brand new just sitting in the box, Im just looking to move up and spend a little more on a avalon. Mine's in PERFECT great working condition. Comes in original box with manual and power supply. Will deliver so if interested please reply back to set up a date to check it out. 450 OBO will work a deal
