Amp looks very similar to the old Messenger line of amps . Up front , amp is a little buggy but works OK , medium side is out and the max side produces a very large DK ......with 2 watts in Low side does about 25 to 120 and High side does about 50 to 200 pep ......the SRF 2072's are 65 watt devices so there pretty much doing what they should. 60.00 Shipped Priority mail same day or next thanks for looking.
