Carl Martin Bass Drive:
We were off to a bumpy start here.
First thing I noticed when plugging it in was the wall of noise. Not like a drive unit with an unusual amount of floor noise. More like the instrument cable is shorted noise. I could not make it work properly and it sounded like a broken speaker at best. Troubleshooting led to the obvious answer: It's the tube. Apparently, it got shaken a bit too much in transit, although it was packaged fine.
I only had a 12AT7 lying around from the Tube Drive experiment, but I did open it up to change the tube. That device was not constructed with tube rollers in mind - but of course I managed to wriggle out the old tube and get in the new one. The noise was gone now, so that's that.
I only tested it for a minute, thought it had not enough gain and it sounded quite dark, so I set it aside.
I managed to find a proper 12AX7 tube, which came from a Fender Hot Rod Deluxe, and slotted that into place.
The gain was corrected and I believe that what I'm getting now is what It's supposed to sound like, but it remained dark.
I have the feeling that when playing with headphones, my dry sound has more treble content than the wet sound with the treble knob maxed.
Then another thing demanded my attention:
Looking at the device, it says "Carl Martin"
Made by East Sound Research, Denmark
Designed by Holm Malmquist
The box, however, says
Bassdrive
by East Sound Research Denmark
Made in China
I don't know if I'm being dramatic here, but the comma makes a difference for me.
Choosing the wording "Made By <company name>, <country name>" Does imply to me that the thing was made by that company in that country.
On the box, it looks like the company name is "East Sound Research Denmark"
In the Danish Business Register, the company is named "East Sound Research", and on the Carl Martin webpage, they refer to themselves as such.
I cannot shake the feeling that they've tried to hide the fact that the device was made in the far east and trying to make it look like it was made in Denmark.
Is that Danish Audio Gear Marketing? I want to remind the reader that T.C. Electronics also hailed from Denmark before they were acquired by the Behringer Group - and most of us remember the 'discussion' about their watts.
