Eh.....that doesn't sound very ...ummm...Sykes to me.Yikes, not Sykes is what I’m hearing:
That’s not how bolt ons work
I owned a pair of Mark-IIIs during my playing days. They needed absolutely nothing. More gain on tap and more tone shaping with the EQ than you could ever need. 'Endless sustain - liquid gain...' Yep. Along with full, round mids and tight thumpin' low end. All straight out of the box.
To my ear - every single before / after demo video of a Kruse Modded amp I have heard sounds like they put an EQ in the loop and dimed every slider above 4k.
There is absolutely no such thing as a "Sykes Mod". Aside from his hands, what you are hearing when you listen to the Sykes HUGE and nearly perfect Boogie tones below is a slight modulation (chorus I believe) placed on one of the two split tracks (simple wet / dry set-up by Bob Rock). This will not only thicken / widen the overall sound significantly, but the modulated side will also include the filtering of the lows and boosting of the top-end frequencies that are typical of a chorus-like effect. Having tried this myself, I know that it can be a brilliant sound when the modulation is subtle. When you listen to the Kruse "Sykes" mod, it's almost like he was trying to duplicate / mimic this effect by way of EQ. All of that said, most of the Kruse mod clips I have listened to tend to be pretty bright. It's not for everyone.What is this "Sykes mod" all about in the first place?
Didn't John play stock Boogie amps (when he was playing Boogie)?![]()

My at home "living room" sound does not work well as a live tone as I tend to boost the lows and resonance almost as if there is a bass player in the room. I also have to push the high end a bit as I am not using enough volume at home to really bring the top end of the amp to life. I can also afford to use you a little less midrange as I am not "competing" in the mix in terms of cut. None of these practices are effective live or in the studio.It seems many newbs can't grasp the concept that the ideal live sound (changes by venue) is not the same as the ideal bedroom unaccompanied sound or ideal studio mix with band or your UTube "guitar influencer" channel.
I often record unaccompanied guitar interludes across multiple panned tracks just to listen to the pure tone and range of that guitar, but bringing in the drums/bass/keys requires mixing/EQ.

of course, most of us are...But to your point, Syke's Mesa Colosseum heads were bone stock to my understanding.Yes, I'm quite familiar with such dry/wet setups.
Just wanted to make sure I got my Sykes Boogie history correct![]()
