Well, it's another crappy, rainny day up here in northern ny so I thought that I'd finally post a review and some pics of my current rig. I finally replaced my much used and loved ABM500 EVO-II head with a MK500 mark king amp. I was looking for the ashdown low mid punch but with a clearer top end. Man, this amp really delivers that and then some. It has way more treble response than the abm. One thing that I didn't expect to like some much was that the eq has several sliders for the low end. I have been able to use the bottom 2 sliders as low cuts for boomy rooms with great effect. With the Harmonic Emphasis engaged and at the noon position, I almost have my perfect sound with the eq flat. The di is also clearer than the abm though I do miss the tube overdrive. Im running this head into my much loved bergantino nv610 cab. Im getting a very focused low end and mid range punch that my old eden xlt cabs weren't getting. It works better in bad rooms than my edens even though the edens were still really good. I miss the extra top end of the edens once in awhile but the HE control on the MK500 makes up for it mostly. Over a month ago, I ran a comparison of the MK500 head into the nv610 with a vintage svt into the 610. I was amazed at how similiar they were than different through the same cab. They both had a similar mid range. The ashdown had tighter lows but the ampeg has the tube power amp warmth thing going on. Since then, I traded my ABM500 to a guy for his svt-2 non pro. The non pro sounds almost identicle to the 70's ampeg. I still havn't had a chance to try the svt into the berg at a decent level. Anyway here are some pics of the rig. Take note of the cool decepticon sticker!
