I recently acquired a Redseven Duality 100 amplifier.
I thoroughly researched and considered this amp beforehand, watching numerous videos and reviewing the technical specifications in the user manual.
My requirements were very specific: a tube amp, 3 channels, a built-in boost, 2 master volumes, MIDI implementation, and a high-quality effects loop.
In the past, I've owned many amps from prestigious competing brands, British, German, and American.
The Redseven Duality 100 meets all my expectations. It's meticulously crafted, very complete, designed by musicians for musicians. There's no need for pedals or other boosts. The amp is perfectly self-sufficient.
Even the quality of the packaging upon receiving the amp is impressive, the hallmark of a meticulous manufacturer. This amp is perfect for me, and I hope to be able to use it for a long time.
Well done, Redseven.
Even on the most modern soundstage, it retains a certain naturalness. It doesn't sound compressed or flat.
The sounds come through already well-defined. In the mix, I had to spend less time than usual working on the guitars.
I used to use several drives to achieve certain tones. Now I do a lot of it right from the amp.
Si vede e si sente che non è un prodotto fatto in serie in modo frettoloso. Dà una bella sensazione di solidità. Si vede il tocco italiano al 100%. W l’Italia!
You don't always have to crank it up to heavy settings. At low gain, it has a very musical response.
Il sustain c’è, ma non sembra artificiale. Le note escono bene e il suono resta piacevole.
It’s one of those amps that lets you play all night long without feeling like anything’s missing.
When you adjust the guitar volume, it really changes. It doesn't stay the same. That's a truly incredible result for a multi-channel amplifier.
When you need more gain, it delivers. But it never turns into a muddy wall of sound. The notes stay clear. Perfect for those ’80s leads that I absolutely love.
It has that character that makes you want to stay there for hours. Not too clean, not too dirty. That’s where the Duality100 really shines.
Ich dachte, er wäre vor allem für Rock gedacht, aber er deckt ein riesiges Spektrum ab. Clean, Crunch, Lead, alles mit einer schönen Konsistenz.
Il clean è pieno e aperto. È una base bellissima anche prima di passare agli altri canali. So che sembra assurdo ma con i dovuti paragoni è il canale da cui mi aspettavo meno e mi ha colpito di più. Non ho mai avuto un clean del genere nemmeno da ampli monocanali.
