Had a great time building a cigar box guitar under the direction of John Nickel at Nickel Cigar Box Guitar.

Here’s a detail of the piezo pickup that we installed in the cigar box. The small block of wood on the left is later glued to cover the piezo element.

Making Tracks for the TrackBox

I saw this “cyber” Monday special from audioMIDI.com: Nomad Factory’s Blue Tubes Trackbox for $15 (expires Sunday 12/6). I downloaded it to see if it might replace the TubeMP 12AX7 tube preamp I use between my banjos and audio interface. I use the preamp to soften the tone of the admittedly harsh piezo contact mics I use on my banjos. Driving the tube a little harder provides some welcome compression and the limiter helps tame the spiky sounds from a piezo on a frailed banjo.

In my initial tests, I’ve been pleasantly surprised with how well the TrackBox nails the tube sound–a little goes a long way. And the 4-band parametric equalizer seems eminently usable. Testing it as a VST in Max 5 it used about 7% of my CPU (an aging PowerPC G4) with all the bells and whistles turned on and was closer to 4% with only the tube and EQ running.

I’m not convinced I’ll leave my tube hardware at home just yet–without a hardware limiter in front of my audio interface I  have to drop the input level significantly to avoid clipping. By the time I’ve pulled the level back up I’ve also introduced some noise. The tone-shaping potential of the EQ and compressor might be worth it, especially if I need to travel light. In the meantime, it’s nice to have another channel strip color.
