View: https://soundcloud.com/donnythompson/maggie-2-mix-a-mp3 I recently replaced the stock 12AX7 tube in this mic to a 12AT7. The original reason I changed the tube wasn't to get a tonal difference, it was just that the old tube was causing noise, and the only spare tube I had lying around was a 12AT... but I think it did change the tonal characteristics of the mic, not dramatically, but a bit. This is a public domain song, an old folk song, "Maggie".. I think it's either Irish, or Irish-American in origin, written sometime in the 1860's. I didn't spend a whole lot of time on this, I tracked the vox in one take, so there are a few pitchy notes here and there, but my motivation for doing this wasn't for release, anyway, it was only to show what the SolidTube mic sounded like on vocals after the tube change. Guitars were tracked using an MXL 860 ribbon. Funny final note... the vocals at the top of the song sound a bit different from the tone towards the middle and end... the simple explanation for this is that I began the vocal track just after turning on the mic, and the tube wasn't yet warmed up (yeah, I should know better), so the texture of the mic sounds different from beginning to end. LOL So, for better - or worse - this is what this mic sounds like on my voice. I wouldn't choose this mic for every application, but for something like this piece, I think it works well. As usual, all comments, suggestions, etc., are welcome. d.
