Well quite a few years back I ranted on here about my issues with my new ABM 500 RC head when it just fizzled out at a gig after about 12.6 months of ownership. I know better now than to go online/internet and start railing about MI quality without first searching as many options as possible.
I didn't curse anybody or go off on anybody or anything like that but I was very p.o.'d my great sounding, first very expensive, amp left me hi n dry so suddenly. I'm much better now.
Music store I bought it at was cool in that they let me pick out another amp from their shelves while they sent mine off. I picked a Genz Benz GBE600 and never looked back. When they called me 11 months later to say my Ashdown was fixed, I told em, keep it. I'm keeping this Genz.
But I really liked the way that ABM 500 sounded and kept thinking about that tone. Moreso, when they put out the MicroBass heads but I was still unsure. Still shaky on Ashdown, I got a real good price on a new MAG 300 II head from TBP last fall, so I took another chance at an low priced Ashy just to hear that tone again.
Its quite underpowered for what I mostly need to gig. But that tone is still there and I dig that built in compressor alot.
My best results is when I run the MAG head into my 4 ohm, TB153 cab, using a passive JoBo 5 bass. Huge tone outta that rig, blues band guiturdist loves it.
Now giggin with a Motown/Funk band mostly and when I used the MAG head with my 4 ohm, Eden D210T (modded with Deltalite 2510's) a couple Saturdays ago. I could not hear my P5 out of it at a gig. I was in the PA and could hear the FOH and monitors but the lowend mud was so huge I could not dial it out.
So I brought in my GB Streamliner 900 at second set and all was great again. That amp sounds nice thru that Eden cab. So I guess this MAG head only plays well with certain of my cabs. Of course, I can't use my STM-900 with my Epifani UL410 cabs, no mids at all. So the quality seems to be there, this is a MIChina model. But its holding up so far and even after it fell to the hard floor off my UL410 on casters...TWICE, the first time I used it at a club gig.
So it seems to take a lickin and....well you know the rest. Good luck.
