Yamaha THR10X guitar tone - Iron Maiden "Powerslave" album - Powerslave cover

Many Yamaha THR videos advocate cranking the Master control. It definitely has its purpose.
What I discovered is that raising the Master will increase the thickness, at the cost of tightness, while lowering the Master will increase the tightness, at the cost of thickness. The latter is exactly what I needed to approach many of the guitar sounds of the 1980s that were high in gain but always sounded thin to my ears.
Combining the Brown 1 channel with the Brown 4x12 cabinet and a startlingly low level of Master, the tone was reminiscent of classic Iron Maiden. Because the Master was so low, I needed to increase the recorded track gain in Audacity recording software to be heard alongside the backing track. Equally drastically, I dialed out the bass and maxed out the midrange.
This recording is my result. Settings are shown at the beginning and end of the video. It's not a 100% match, but quite close to my ears.
If you have any suggestions on how to tweak this tone further, feel free to explain in the comments.
I recorded two guitar tracks with exactly the same settings, one panned 50% left playing Dave Murray's guitar parts, and one panned 50% right playing Adrian Smith's guitar parts.

Hi mate its a really useful review on the master volume setting, thank you, but what i really difficult to find in reviews of this amp is, will the volume drop when you switch channel(sound model) mid song? Say you playing with brown 1 for the rhythm part of certain song then switch to power 2 to do the solo? Thank you

Interesting question! Presuming that you designate (and save) one patch for rhythm (Brown I) and another patch for lead (Power II), I would recommend setting these two patches to be even with each other (or with a slight overall volume increase for the lead patch).
In my example, if you use a startlingly low level of Master for your Brown I rhythm patch, and you want to set up a Power II lead patch, you might want to consider reducing the Master on the Power II lead patch to better "match" your Brown I rhythm patch. Otherwise, if you don't, the lead patch might have a large jump in overall volume.
Good luck!

@@axeltuneguitar Thank you mate, I didn't mean switching between the 5 saved presets, simply turning the channels knob in the mids of playing, does it transfer ok? or does it lost its volume and distortion like some transistor amps which forces you to tweak the volume (and or other knobs to recover the volume) and interrupt your playing? Thank you mate

@@rioace3953 OHHHH I understand now! Turning the "Amp" knob (to switch between Power I, Power II, Brown I, Brown II, and Southern Hi) results in no loss of volume or tone when changing between amp models. You can see this in action in Ola Englund's THR10X video where he is twisting the various knobs (including the "Amp" knob) midway through the song and the levels stay consistent. ruclips.net/video/grogLHqCGhU/видео.html

@@axeltuneguitar Thank you so much mate, yes that was exactly the question. And your findings about the thickness versus tightness is definitely a useful tip. I wonder if you ever tried running any type of pedal that could maintain tightness as you increase the master volume? Definitely no pedal that cost more than the amp itself though? Cheers

@@rioace3953 I don't have any overdrive pedals to test the following theory, but it might be worth trying an overdrive pedal in front of the THR10X to possibly tighten the sound. A "normal" amp tends to benefit from increased tightness when the overdrive pedal's level is set high and its gain is set low. If you get around to trying it, let me know!
