OK, I admit this is kind of a rant stemming from my personal frustration in the past few years concerning reliable amplification. But, have you noticed most of what is available is just not working, sounding good, or even leaving you stranded on a gig?
As I have aged, I have sought lighter weight solutions to my rig. It started with moving away from large transformer power amps to A/B class switching amps. In most situations these lighter weight (14lb) amps are outstanding, offering high power and reliability as long as the power source is consistent. They just don't like to run on generator power, so my solution was to maintain one of my old big transformer amps as an alternate. Even with the lighter amp used in conjunction with an F1X preamp, the rig gets heavy for me to load in and out comfortably as the three herniated discs in my back take their tole.
My next solution was to try the new generation of D class amps in small packages. I tried virtually everything from Darkglass to Demeter 400 and 800, Markbass Markus Miller, Fender Rumble 800, Walter Woods Blue Light, TC, Quilter, Mesa, Genzler 350, Behringer, Aguilar etc. Most were either lousy sounding, or severely underpowered. A few just plain blew up like the Markbass, Demeter, and my latest, GRBass 800. The best performers by far were the Behringer and the Fender Rumble, but I simply can not get anything approximating the "Alembic" tone from any of them. Sure I could add a Super Filter to the mix, but that is something I would prefer to avoid.
I had high hopes for the GRBass 800 Cube combo in carbon fiber, and found it to have great tone, ultra light weight, and it was loud and responsive. Alas, the amp section and tweeter fried on my last gig.
So why can't anyone test their products under real world conditions to assure reliability? And why for God's sake can't anyone attempt to duplicate the magic Alembic tone which has been available to copy for 55 years?
