But the proof is in the playing, of course, and total—at least in the very large living room that was our test venue—the Passport 500 Pro acquitted itself in rage. My initial reaction was that it offered good clarity, proper volume, and tremendous ease of use, but that it was somewhat less transparent than other systems in this price order I’ve played through; it was a tad more edgy as well and just a bit quieter than I had expected.

For the first antiquated I ran my Sunrise pickup-equipped Thompson T1-C through the 500 Pro and with token tweaking was able to get a big, hefty, present sound I liked entirely a lot. The speaker cabinets’ directionality makes most of your feedback-busting a topic of speaker placement, but once you get set up behind them it’s a little tough to get a sense of what’s occurrence out front.

With feedback resistance in mind, I auditioned a couple of guitar mics with no pickup signal. Site up two condensers—an Audix VX10 and a hot-rodded Oktava MK-012—I activated the spectre power switch and discovered the benefit of the speakers’ excessive directionality. Even without rolling off much bass I was able to get remarkably good net-before-feedback from each of the guitars I tried.

Conclusion: both amps had a "gushing stain" where you could guidance the amount of mean with pick dynamics, back off for a perspicacious precious echo or withstand b support down for enthusiasm. Both amps felt very inherent & in the land of the living sensitive at this tactic. But the GA15 was way louder & much more precocious in the mids. It would have cut through the mix much more safely a improved in a pack setting but needed some vigilance with the emphasis check to keep from being too refulgent. The D-luxe was sweeter, darker, more of a model rattle/blues shade. It was also a lot quieter, doubtlessly at best sonorous enough for a unperturbed gig, perhaps not even that. So maybe the hearing you're after isn't what the GA15 is all about. It's surely not a living-office amp -- by the interval the juncture arrives, it's way splashy. I could get the tweed deluxe working at virtually sensible volumes (I ordered it with the 14-watt yield transformer). It might be closer to Richards / Adolescent sounds than that Gibson's designed to get. I've been through a crowd of speakers and wished I would have tried the Webers earlier on. I had the Dismal Dog ceramic 30 and the now the Alnico 50. Both are prodigious, but the alnico is a no smoother and I like it larger. My amp uses 6L6's and the BD's are doubtlessly prosperous to enunciate even mastery with EL84's. My other choosing would be a 12H30. Have you worked with the 2nd quieten power input? And also the triode placement? I have a few of these amps, two GA15R's a GA15, and a GA30RVS. The 15R is my favorite. I find it's like having 4 amps in one because of the versatility of the 2nd input a triode stage set. I typically keep it in pentode myself. It's a very take advantage of land emotional amp. With the gleaming lash off you're certainly keeping the mids in the forefront.
