check this guy out. What Marshall amp and speakers do you think he is using. Looks like his guitar does not go into the high treble input like Hendrix does live. Interesting

i remember seing this video, but now that i see it again, wow, he's very close, very very close, nice player.
from what i saw on internet, it seems that he uses a 69 plexi. but it doesn't mean he uses only this one for all songs.
it doesn't mean it's el34 Inside , it doesn't mean it's not a 45/100 why not.

This the real tone here doesn't any one have any input. This guy has nailed it

His facebook page. You can also see what he uses. Seems to be a stock 1969 half stack.

If the amp is truely unmodified; with the exception of the key thing; then plugging into the Normal channel would/could yield a tone similar to what Hendrix Bright channel was like. Any additional 'tweaking' to get it to sound right would be done via the tone controls.

It does sound very nice, very close. The mix/reverb and possibly the room it was recorded in does seem to have a positive influence on the sound.

I'm putting my money on that amp being a Super Bass...plugging into the normal channel on a 69 SL does *not* sound like that. With a shared cathode it'll be close, but not with a split cathode. In a split cathode amp the normal channel is very gain and round/dull sounding, no way you would get those clean spanky Power of Soul tones that way.

[Tazin]

If it was a Super Bass wouldn't it be even worse plugging into the Normal channel?....That's where it looks like he's plugged into.

[Tone seaker]

what do you think his settings might be

On a Super Bass, the V1 cathode has a single 820R/330uF combo shared for both halves of V1. This makes it 1640R effectively.
On a Super Lead each of the halves has its own separate R/C combo, so the normal channel has 820R/30uF alone. This yields considerably more gain, and makes for a fairly muffled tone. Even with the different tone stack and smaller PI coupling caps it is very middy/muffled sounding - perfect for blending in with the bright channel, but is almost unusable on its own.

So in reality the normal channel of a Super Bass is actually a little brighter than the normal channel on a Super Lead, or at least appears that way.

Of course, there are some indications that Jimi's SLs were slightly modded, and one of the mods was bringing it back to shared cathode.

I don't see were the 1640R cathode resistance comes from on the Super Bass when there is only one 820R resistor for V1 (a and B).

[Tek465b]

820 R for both equal to 1640 for each halves. (most of them like to think about it that way, make it easier)
Since you have 2 device(v1a and v1b) connected to the same resistor, they draw twice the current. IT increase the cathode voltage and change the bias point(colder and also increase v1 plate voltage a little)) and also change the gain of the device.
So it look like it is 1640 ohm for v1a and 1640 for v1b.

yes, and the 330uf would look like a 165uf for each half of v1?

the corner frequency should be the same for the RC combo.(820R/330µ).. or 1640ohm and 165µF. Depend how you see it.
Both make it to about half a Hz.(same thing).
The shared capacitor dont have an impact on the circuit as much as the shared resistor do.

edit: there also the de-coupling cap difference 22n vs 2n2 for V1a vs v1b plate.

[Tone seaker]

so you guys think its super bass or lead he is using. and how is he getting the exact Hendrix tone in the normal channel wher Hendrix used the lead channel

[Tek465b]

Well on the superlead(68-69..).. it's just a bit more gain on V1 normal channel for split cathode.. just reduce the volume on the fuzz or whatever is your last pedal in the chain.
Maby hendrix had 22n swapped instead of the 2n2 for the bright channel plate. or some other non-standard value, who know
That will be just like a 67SL preamp.
