Continuing with the Rack units… but… I’m not getting a rack… I’ll just use them as heads…

Man is this thing powerful or what?!? So… specs are: weighs around 22 kgs it has 2 output transformers capable of delivering 2x 95 watts each, you can push a lot of cabs! 4 in total if you use the outputs… however… with a cab switcher… you can push 4 16 ohm cabs per channel… a total of 8!! That’s a full Stadium rig!

6L6 and El34 tubes, so each channel has 2 modes.. Class A through the EL34 at 30 watts, or Class A/B at 95 watts using also the 6L6. What’s cool about this… well… apart from having different tones… you can run the channel at 30 or 95 Watts, which makes quite a bit of difference.

In total this unit has 12 tubes, which translates into £200 for a whole set of JJ tubes… it has 2 channels with independent stand by switches and volume knobs, it has 2 presence controls… one for each channel.

The volume knobs are just great, they behave like a hi-fi knob, you can just tame the volume to any level you want, but more importantly the volume sweeps in a beautiful way, there’s no sudden increases or drops like on Marshall amps.

I use a custom made amp switcher.

I’m running this power amp together with a Studio Preamp, this is pushing 4 cabs at a total of 4 ohms, and man…. this thing sounds huge! Also loud… but the sound has this 3D sort of thing about it, pretty much like a Matchless, I’m not entirely sure if this Power amp colours the tone or not… but I’ve read that some people are actually using it for hi-fi, so I’m guessing the unit just amplifies whatever the preamp is putting out.

If you’ve read my other posts, you’ll know that I’m after the AC/DC Donington 1991 sound, during the razor’s edge tour, this combination of the 295 abd Studio Preamp pretty much nails the tone, it’s almost addictive!

I’m yet to use this in a live environment (thanks Covid 19) but I’ve played relatively loud at my studio (100db) and it is just a gorgeous tone! Of course I’ve been testing it with my SGs.

I hear that rack units are out of fashion… and people are buying 15W combos or heads… I’ll tell you what people are not thinking about… headroom… 100W is loud… but… running a 100W amp at half volume sounds much nicer than a 20 W amp at full volume, the articulation that you get with the massive transformers of a 100W cannot be achieved with a 20W head/combo.

The Power amp plus the preamp weighs a total of 26kg. My Marshall 1987x weighs around 15 and an SLP 1959 weighs 20Kg… so… yeah.. these Mesa are heavier, but can you out a price on tone? Would you care carrying an extra 6kg if you know your tone will be much closer to what you want?

Of course not… 6kgs is nothing… just ditch some other crap from your rig. These units are outstanding and I’m pretty sure that they will come back into fashion soon.
