- ~Well, here's an OK hardware hack:
-
- ~This year, I've modified my Yamaha PSR-500 keyboard for use in the Stanford
- ~University Marching Band. It's the only regularly-used keyboard I know of,
- ~in *any* marching band. Has anyone heard of another?
-
- The YPMB has had a grand piano on the field during halftime. We
- also have a guy who carries around one of those miniature Casios.
- Your setup is more impressive, but not unique. We've also had a
- 'cello, but that's closer to stupidity than a hack.
-
- ~Volume was a little harder. The Yamaha uses 9-12 VDC power, so I
- ~bought a 120W car stereo amp, on special at Radio Shack.
-
- ~I get power on the field from a 20 Amp-hour motorcycle battery, cost around
- ~$40.
-
- When I was in high school, our marching band had an electric
- guitar. It also had a cart with a heavy duty car battery, a
- 12VDC-120VAC inverter and a large Fender amp. One guy played the
- guitar, while someone else pushed the cart around. Could you
- find a volunteer?
-
- ~It weighs about 15-20 pounds, all told. That's less than a bass
- ~drum or brass tuba, but more than a fiberglass tuba or any other
- ~instrument in the LSJUMB.
-
- Just when I was beginning to respect you, you go and mention
- fiberglass tubas. 0.5 :-)
-
- ObHack #1: Last fall I spent a couple afternoon in the metal shop
- attempting to fix an alto horn so I could join the YPMB. I
- learned a lot about making weird sized screws. Two weeks later I
- found a working alto horn in the back of the instrument room
- which I used for the rest of the football season.
-
- ObHack #1.5: For basketball and hockey, I didn't need as much
- mobility, so I used a euphonium since it played better. The
- problem is, I can't play on that large a mouthpiece. So I took
- an old trumpet mouthpiece, cut off and discarded the cup, drilled
- out the shank to accept a french horn mouthpiece and held
- everything together with duct tape. The best thing is, the
- resulting combination worked better than some officially approved
- and recommended mouthpiece/horn combinations.
-
- NonHack #2: The preceding shenanigans were becoming tiring, so
- this fall I went and spent large amounts of Real Money on a King
- marching horn. It's in tune, loud, and a joy to play. Not a
- hack, but a fine work of craftsmanship.
