Taming the 5150III Stealth 100 6L6

Hey all.

Been trying to sell my Stealth 100 for like 8 months to no avail. Oddly was selling for a steal at $1600 and nothing but shitty tire kickers.

Since I’m stuck with it, I’m trying to tame the overall gain sweep if possible. I kinda hate the amp but mostly because the gain goes from off to full bore at like 8:00…

I have a few lower gain preamp tubes. Just wondering what spots they should go in.

holy smokes that's a lot of preamp tubes!

@JerEvil what speakers/cabs have you tried with it?
Tried it with my Friedman BE412 that’s got GB/V30 mix, my K100 loaded Marshall and Redback loaded 212. Gonna swap those speakers for a Weber Silver/Greyback combo and see what that’s like.

geeze, that's a pretty good mix. Hope the S/G combo works out, a lot of people dig that amp. It was on the hitlist at some point.
 
I post this dumb clip all the time, but this is a 5153 100w EL34 on the Blue channel with the gain just barely cracked open, like 0.5 out of 10. All stock. There isn't a ton of room on the gain pot to get this kind of sound, but it's in there if you're careful. The Blue preamp of the 100w Stealth is identical to the Blue preamp of the 100w EL34, so you could get this exact tone with the Stealth also, but with maybe very slightly lower mids but you could just turn the mids up a hair to compensate.

The amp settings never change, just the guitar pickup selection and playing dynamics, that's it. Start of clip is an EMG 89 in the neck, coil tapped. Middle of the clip at 1:15 is the 89 neck in humbucking mode. End of clip at 1:58 is an EMG 81 in the bridge.



I made it to show that the amp doesn't have to be a 100% firebreather all the time. Actually I tend to think of the 5153 as a slightly harder sounding, more modern high gain Bogner Ecstasy. I've got a 101B and if I boost it and cut bass at the input, it and a 5150 III are a lot more similar than anybody would think. Like they sound almost the same.

Anyway, I posted this clip here to show that if you can't sell the amp, maybe you can at least use it to fill another kind of gap in the tones available to you.


edit: I also wonder if you could have the amp modded for a different gain pot. The schematic says the Green and Blue channels use 250k pots with log30 tapers, which means at noon, the pot should be set to allow 30% signal to pass through it. A linear pot would allow 50% signal pass at noon. The Red channel uses a 1 meg pot with a log5 curve, which means that at noon, only 5% of the signal is getting through, if you can believ that, lol.

I'm saying that if you want a more flexible Blue channel, you could try to find a 250k pot with a lower log value, which would give you more knob sweep resolution at lower gain settings.

according to the Euro tubes website, V4, V5 and V6 are for channel 3 (red).
If you replace two of those with 5751's, you'll drop the gain a decent bit, without sacrificing the base tone.
If you change V1, it'll affect all 3 channels obviously.

I’m definitely going to try the 5751 in the V1 spot first. I’d like to see if I can make the green channel and actual clean channel, and also tame the red channel. I kind of wish they would make a single channel version of this amp with just the blue channel. I’d buy that in a fucking second.

Dude I like that :cool: sounds nice(y)

Man, not only did I really like those tones, but the plane was also super fucking tasty.

Keep the Speakers. Crank the Amp to at least 3/10

Thanks dude!

Yeah man that tone is in there if you dial for it. It’s easy to never attempt it though as the amp is marketed and played by basically everybody as, well, a 5150. :D

That clip was guitar straight into amp btw. Again you have to get super deliberate with the Gain knob to get that sound but there it is!

Oh I barely crack the gains on this amp ever. Hence the question here. Maybe I need to move from the Stealth to the normal version…

You could do that, but the core tone of the OG 5153 is just a bit different than the two 100w stealth versions imo. Even at the same gain settings I’ve always preferred the Stealths over the OG. The stealths just seem a bit more lively.

Here’s the best comparison I’ve heard of the three amps:

 
When I had the 50W Stealth, I tried a 5751 in there and didn't love it. Can't remember for sure but was probably in the V1 spot. To be fair, I prefer less modern tones boosted to tighten them up a bit. Still want to spend some time with EL34 100W for some reason.
 
In general. I don't think there's taming.. The amp is what it is unless you do real modding, and then it's a different amp.
I tried this with a Jet City 50 combo.. Fucked with it for years but never loved it.
I ended up turning it into a Deliverance LOL..

Yeah I’ve seen this. Oddly I like none of these tones and generally don’t like to see this guy gets. He has the same RedSeven D100 pre I have and never liked how he made it sound either.

Take the skirt off Jeremy! Gain is good!
