Chapter 5. DeskBeam Bass: > The DeskBeam in Principle - Pg. 147

MAKE: PROJECTS Eccentric Cubicle height/offset adjustment screws at each end of the string course are the only concessions to setup variables in the instrument. If you want more control over intonation, your best bet would be to cut individually positionable frets for each string and wedge them under the strings at the head- stock end. This would take you about 10 minutes to accom- plish, but likely wouldn't be worth the effort. Material-wise, this could easily get complicated, depending on how just-like-a-real-instrument-ish you want it. If I were making a standalone 'Beam, this would be an issue I'd obsess over at the drop of a hat. For the purpopses of this particular project extruded aluminum angle bar, 1 / 4 -20 threaded rod, and a motley assortment of nuts are core components. Our material choices for stringing this monstrosity are many and varied. I've made 'Beam instruments in a number of different scales, and have strung 'em with everything from actual grand piano bass strings (Awesome, absolutely awe- some. More awesome than you could ever hope to imagine. Really, really awesome. And expensive. Really really expensive) to 30-strand twisted-steel picture frame wire. (Not in any way To make a reasonably warp-resistant neck/body, you'd have to knock together two 2" x 4"s into a T profile, which would mean carrying around a hammer and nails with you. You'd also need a drill and a 5 / 8 " spade bit to drill holes in the lumber to accommodate the shafts of two tripod mic stands, if you didn't want to have to sit on the floor to play it. Oh, and a handsaw to cut your purloined lumber to length. All of this lies well within the realm of the do-able. You'd be sacrificing acoustic volume without the presence of the desk, which is probably for the best from a feedback perspective. Don't expect anything less than 18" and at least 800 watts of power to do an adequate job of enlarg- ing the piezos' signal to acceptable levels. Reproducing the extreme low-end content of a 'Beam instrument eats up headroom on your power amp like nobody's business and entails . . . er . . . expansive speaker cone movement. If you're not using a Derek Smalls­scale backline, you're much better off running the 'Beam into the house system via a direct box. Plan on buying a few beers for the sound guy, and don't be
