I was very pleased when I sent for this amp (Bass Central, a great bunch for sure!) and finally opened it up to try it. The build quality is exceptional in and out. Good quality jacks, pots and cabinetry throughout. Though it only has a simple 5 band rotary eq, it is VERY effective and can be switched out of the chain if necessary. The input pre is VERY high-headroom/low noise and of course the signature Ashdown backlit VU is a useful and welcome retro feature. In addition to the 5 band eq, there are switches for deep and bright, which are not overpowering yet create above-subtle changes in tone. The sub octave is more of a tone/timbre control than an effect. When used sparingly, it creates a nice extension to the bottom end without creating any mud.

Power wise, this amp can dish it out. It's not the loudest head I have owned but definately STRONG. The dual fans help keep it running cool, something all amp manufacturers should realize. I mean c'mon fan cooling bass amps consistently goes all the back to the earliest of SVT heads!!

This is a very well built amp for the money. Currently I am only powering 2 SWR WM115 cabs but it still cranks. It will really shine with an Ampeg SVT 810 or 610hlf cab!!

If you cannot afford the ABM series amps, be sure to check out the MAGs!!
