Thanks! 😁

When his camera shakes you know the amp is happy!! 🔊🎸

Thanks my friend, rock on!

Agree completely. I built a two channel amp with both. It's versatile, and doesn't leave me wanting. I highly recommend.

Same.

Thanks man, great to hear that!

Thanks man, it actually was that cold

Unheated practice space, eh? Here in Austria we only had -5°C, so not too bad yet. Also superb playing as always! You always manage to come up with the catchiest riffs. Makes me want to grab the guitar and jam along.

Thanks my friend! Glad to see you here.

Yeah I tried to make Strats work with vintage 2203’s for many years and wish I had my stock 71 1987 back then. But even though I play LP Specials with P90’s or humbuckers now, I still slightly prefer the 1987 to my stock 79 2203. There’s something about the low mids that make the 1987 warmer at any setting.

Thanks man! See you!

Thanks, glad to hear it!

Those pulsonic greens are a major factor here I’d think

Thanks Todd! That’s a good point

Yeah, the 800 has a bit more gain than that, but the comparo works as to the change in tonality in the cascaded vs non cascaded designs at a similar gain setting.

I would have liked to have heard the 1987 with the channels jumpered.

1987 by far for me. Thicker and more " grunt ". The 2204 is brighter and a bit more edgy in the distortion. Still very nice but 1987 all the way for me. Nicely done.

Thanks John! They sound great with an attenuator at bedroom volume level too but it isn’t as fun of course

Tackar! Gott att höra

Thanks! I’m having one sm57 perpendicular to where the dust cap meets the cone and another one 45 degrees to that in the same horizontal plane.

That’s an interesting reflection. The bright cap on this 2204 is 1000pf. I haven’t checked the one on the 1987. I think the 70 schematic says as much as 5000pf (.005 nano farads)

@@JohanSegeborn This is one comparison video I always hoped you would do! Always wondered how they stacked up. I never knew what the caps were-at 5000pf, no wonder the bright channel on the 1987 is so piercing at low volumes. Haha. I just knew when at bedroom level when I jammed at home in the 70’s the bright channel on my 1987 (year 1971) was too thin and bright until I discovered cross-channel/jump-channeling. It made a Big Muff Pi sound good back then for learning Ritchie Blackmore solos. Then in the later 80’s I had a couple of early 70’s 1959 models and one 1969 Plexi modded for master volume plus the same caps (on the 2204) put on pull pots because then I could have the deeper sound if I wanted but also one OR both caps engaged to get that modern master volume sound. Even with both caps engaged the amps still sound thicker and more bassy than the 2203/2204 series. Even though some players wouldn’t like the bassy sound, I needed it when I played in my church in order to make the amps sound more like they were played really loud with the natural low end. They worked quite well.

Thanks Ronnie! 😆

Thanks! Glad to hear it

Thanks! Glad you like it

Indeed!

Hi Todd! I did a bunch of videos of the SIR studios mods together with the Swedish amp builder Daniel Forsberg earlier here on the channel.

@@JohanSegeborn doh! Sorry I missed that.

Thanks man, I’m afraid I instinctively maximise the master as a first order of business, but I see your point. Maybe a topic for another video

Thanks, interesting feedback

I agree with that. I’ve never been big on amps that use a really large cold clipper. It adds a cool sounding edge to very saturated lead tones (like in a SLO, Recto, or 5150), but doesn’t clean up well from the guitar volume.

Cool, those are really rare!

Thanks! They are in the thumbnail actually!

@@JohanSegeborn I did try zooming in but it was too blurry to decipher. 🤘

Thanks, glad to hear it!

Thanks glad you like it! I edited out when I switched amps

I’ve got a stock 70 Superbass and it’s a great amp with the vintage Marshall sound, but it’s a different playing experience to the Lead spec amps. No way would I want my stock 71 1987 and 79 2203 to lose that upper mid Kerrang and sparkle in the rolled down treble.

Aloha!

Thanks Dominik!

I think all 2204´s have cascaded preamp tubes and a MV.

@@qddk9545 no the first 2204‘s had the mastervolume but not the cascaded preamp that the 2203 already had. Strange decision, but they corrected that a year or so later

2204 has more gain but the 1987x has more tighter useable gain

Thanks!

Thanks, yeah it becomes fatter then but usually too rounded

IME jumping channel’s doesn’t add any more gain, if anything it’s the opposite. As Johan says it just makes the amp rounder sounding, which is the opposite of the 2203/4 sound

@@zachariahwade8482 it depends on how you are using the jumped channels. With both volumes at the same level the overall gain is significant higher cause you are using both halfs of the triode’s

Sure! Bluetooth Marshall speakers and headphones for $500. 😂

😂

Thanks, glad to hear it!

Thanks 😆

No on the contrary, These are brutally honest

Good thing for Johan - he’s a talented badass w/ badass gear💪🏼

Not pointing fingers. Just good advice learned the hard way.
