Question about power amp input impedance

Power amp’s 10k input impedance is plenty fine with a preamp’s 1k output impedance. No problem there.

Bumping an old post. Thanks for this info looking at a 1st version at a good price.Just a friendly reminder to everyone: There is a trimpot on the preamp. This controls the overall gain.
IME, basically all of the preamp noise can be dialed out simply by lowering the gain on this so that the level of the pickups when passive is the same as the level when the preamp is active.
HI Arguz, I know this is a very old thread, but I’m hoping you’re still active. I have a Stagg EUB and has all the same problems everyone is talking about. But one part of your posting is especially interesting to me….the settings on you Rumble 50. I have a rumble 100 and have been wondering what settings others used when trying to Arco. Can you Tell me how you set yours? By the way… try putting one of those small, thin, felt sticky pads under the D string on top of the bridge. I have two of them and it raises the string just enough to approximate an acoustic bridge. Much easier to bow.I own a stagg since 2 years ago and mostly played with bow, I use d'addario helicore strings and so far I had no volume issues, although as you mention pizz is far more appropriate for this instrument.
For Arco I crank the second knob in the stagg almost at maximum, I use a Fender rumble 50 and play with the effects it has for a better sound, but just to get a better tone, not volume.
One issue I did find is that strings tend to have a lot of resonance so I put some micro fiber below the strings to damp the sound in the upper side and some sponge below the bridge, I know it sound strange but it has given me fairly good results.
Still strings seem to be not as responsive as if it were an acoustic, it require a little more effort from the bow, not so much as pressure but more "pulling" if you know what I mean.

IIRC, it was a green pad:Love that and I alos prefer a satin or unfinished neck. Do you remember the grit of the pads?
I put La Bella Black Nylon Tapewounds on mine...man do they sound great on this bass!La Bella Original 54 Flats. I’m a flat guy.
You too man. That CAR amazing. Beautifully played and broken in. You should grab a set of the original reverse klusons and throw them on.Sweet bass! My neck date stamp is Jul 65 so definitely in that timeframe.
Awesome- I have the same problem!Thanks Kirk. I took the unit in a specialty shop and they found the size. If anyone else needs the machine screw size, it is 4-40 x 5/16. This was a common issue. I went ahead and cleaned in the inside, and it sounds like new again! It's a killer amp.
This is one of the best StingRay models ever produced.I have been very impressed by the various discussions I've seen.
Holding this instrument in the photo, I noticed that I really like the fact that it can switch between passive and active, and its tone suits my taste perfectly.

I think the big tradeoff is weight. I have one of the maple/alder ones and it is light as a feather which is great for performance (in fact it is my “main” bass even with a Woodstock NS in my arsenal), but the all-maple is going to be more similar to his own instruments and the classic NS-2.His tone and technique, and a long history with Spector (and almost Ibanez . . . ), I'm not surprised he preferred the one piece maple wings.
Thanks, DP.

I am in possession of it. My wife inherited it from a family members estate.Wow that’s a rare bird! I own CS-74 #3 and I’m very sure that’s 100% authentic. You won’t find those particular pickups anywhere else, and all the details appear correct. Tell us more about where you saw this!
$2500 is a good price for these MSRP.With tax you’re talking right at $4000. With Jason’s price at fret nation, along with him not charging sales tax, you’re paying almost half off with today’s pricing. In 2024, the 4 string version was $2650.
John Paul Jones talks about doing the arrangement and playing bass on it in the documentary movie Becoming Led Zeppelin.I believe it was John Paul Jones-I saw it listed somewhere in his list of studio credits.
Being that he was an extremely busy session guy between 1962 and 1968, it is quite possible.
