S.I.R. 100W SuperLead Schematic pt. II

[CoffeeTones]

Solo is fine, the other is smooth and thick. Might try a little more NFB - 56k to 91k @ 4R, or 15k to 22k PI tail, or smaller value presence cap - .1 to .47uF. If you choose to go that far, the 25k presence circuit might do the trick as well. That will definitely take away some tubbiness, give more top end and sizzle.

The .1 has been in and out like 5 times now. But I tell you once you stick the .68 in there it's like crack..... you just go ooooohhhhh that's nice.... Then you put the .1 back in and your brain reminds you on how sweet that .68 was and all goes south from there..... I guess this is the point where a switch would be an idea. I will see if I can get that 25k in there and do some clips with that at one point.

.33 or .47uF can give some of each end of the spectrum by pot adjustments. I'm not pushing the issue, but it's worth trying to use each circuit (5k and 25k) with each cap value.

This discussion reminded me of something I saw a while back. Pretty good stuff https://www.youtube.com/watch?v=MWTJs3HMG3k

For clearer reference to the mid tone and more https://www.youtube.com/watch?v=y0wFTWHjQtc

What many modders don't achieve is the mid and high voice of the #36 / Jubilee tone.

Just for you then. More mids and highs:

A little too treble peaked and thin in the mids. What did you change?

More mids then:

Tried to get more of the C80 and less of the V30. But crap this amp is føkkin loud as føkk.... I think the dog is stating to dislike me.....

[gluke]

A tad to much gain for the rhythm parts me thinks. Sounds more right for the solo:

I'm being picky, but WTTJ sounds fine, the solo and Nightrain are too compressed and the top end is not clear, like it is coming apart / garbled. Maybe tweak some voltages a little via the droppers if you want. The mids are close, could be a little more skewed toward the top. It might be interesting to put a cap on the mid pot like Marshall did in the combo amps. Not necessarily the same value though.

That said, you are the one in the room with the amp. As long as your are satisfied - run with it.

[CoffeeTones]

Ya might also adjust the treble side of your pickup down 1/4 to 1/2 turn to see if it clears the top end.

Not sure I wanna be in a room with this amp anymore. I turned it up to 4 and holy mother of cow! This amp is evil! He called it Levi superkill because it was actually designed to kill people.

I need to take a brake from this and hopefully recover some of my hearing......

I used to do all my clips at MV 4 lol, I was always waiting for the police coming to the door lol,
Anyways your amp is sounding good
Tweaks for too many mids, 470k500p before the pot, and maybe 250p33k TS

That it just Nøkkin Futs! Honestly it is brutally loud at that point, so I have no plans of doing that again. I am used to testing my Metro Plexi kits with my GB 4x12, but this is in another leauge altogether. I was hoping to roll off som highs and lows at some point, but nope, still the same just a million times louder. I was thinking that maybe the cab would start giving in a little but no luck there either...... so next up is a Fryette Power Station.

250p??? I though Y’all agreed that the TS was stock???

A few suggestions - You may want to ditch that 5n bright cap and try another workaround. Then your gain will be controllable and you won't be forced into so much brightness. These amps hide their true color until you crank the volume / master, then it becomes a different amp. Many times unbearable and bad sounding when controls are opened up.

A 470k // 470p, 1n or 2n2 combo prior to a gain pot can lessen the bass, tighten the amp and make it somewhat more woody. To me a 470k with no cap can sound better than 470k // 2n2 by sounding much the same, but is a little tighter.

You can tailor that combo to 220k // 1n, 2n2, 4n7. That will introduce more bass than the 470k and allow you to tune the brightness. You can still use smaller value bright caps to capture some woodiness and other effects. IMO, the 5n bright cap just makes the amp more of a one trick pony because it is too bright until the pot is almost maxed out, in order to kill the 5n brightness. Then you often have too much volume /gain.

If you choose to ditch the 5n bright cap, you might then need a smaller presence cap value on top of the other things mentioned above.

Be careful, you can easily damage your ears which will cause swollen nerves and ear parts, giving headaches, ear ringing and possibly nausea for several months. Use ear protection or isolate your self from the volume. Rely on your recordings to tweak the tone.

A PPIMV can work great, but also hides the true character of the amp when turned down, so you still have to tweak the amp with controls somewhat turned up.

I don't really know if it was in the 36 or not, but it sounds good in some amps, depends on how bright your amp is,

New day new spec no more 5n bright cap:

Sounds a lot better in the top end. Highs are now clear and not breaking apart. The mids are nice and vocal. About the only difference I would shoot for is making the lows a little more vocal, thick and bouncy. Possibly, slightly bump up the value of a cathode cap or coupling cap. Could increase the PI output caps a a bit, as a last resort. No idea what you have now, but sounds like maybe a 250p treble cap and / or peaker combo addition. If you did change the treble cap, you might increase that as a test as well. If you added the peaker, the resistor value could be lessened and cap changed to get the same high frequency, but increase bottom end.
