Stompbox 1.0

stompbox-v1Stomp box made from a Musician’s Friend shipping box, cardboard tubing (using inside for support), and packing tape.

A contact pickup from Radio Shack was placed on the box with double-sided tape. Wire was soldered to the pickup and routed to a pill bottle fitted with a 1/4″ jack. This was my dad’s idea from a previous pickup experiment. In this incarnation, the signal was processed with a tube compressor (could also use a preamp), then into my pathbay for other routing.

Technique: The box above is played with the right foot. I used the box almost as a footrest with both feet on the top. This helped with my posture while also allowing me to play without the box sliding across the room.

contactcloseAt the time, I was using the Roland VS-1680 as my recording medium. EQ was applied there. One problem with the cardboard prototype was caused by the plastic tape that I used. I got a “sticky” tape sound along with the more thud-like stomp. This could be avoided with paper-based tape, or glue. Using my left foot to dampen the box helped keep the stickiness to a minimum. My next prototype will be wood, eliminating the stickiness completely.

To hear an example of this technique, check out “I’m Goin’ Down” from Cadillacs & Tarantulas. A new version of the stomp box is in the works using wood and a second pickup.

Wrench Gamelan

im_wrench1-754263“Chaos Factory”, one of the songs on Immaculate Misconceptions required a clanky type of rhythm track. The sound in my head was much more processed, but I thought I would start simple with whatever metallic stuff I could get my hands on. Some wrenches from my toolbox and a couple trips to Lowe’s later I had a working concept for a gamelan of sorts.

im_wrench4-779626Assorted Melody Bolts
Bass Wrenches: 7/8, 1”, 22, 15/16
Striking wrenches: 11/16 & 3/4

There were two funny things about this little project. The first was during one of my trips to Lowe’s. I was checking the tone of the bolts by dropping them on the cement floor. One of the associates walked by and said, “I don’t know what you’re doing, but it doesn’t look like work!” I’m still not sure what that was supposed to mean.

The second funny part was during the recording process when I realized – despite all my attempts to the contrary – that this collection of metal objects actually sounded too pretty. A few attempts at pitch shifting the sounds resulted in some interesting textures, but nothing that would work in the context of the original song idea. So I left the processing out and just recorded a rhythm and solo track of the gamelan and left it at that. The result was much more perky and bright than what I envisioned, but there’s always room for a remix on a future collection.

Drum Tree

perc_drumtree09The Drum Tree is definitely a work in progress. This picture was taken 2/28/09 and shows the current configuration. This “instrument” was a product if the rather crammed quarters of my studio space over the years. There’s never been enough space for a drum kit, so I’ve just accumulated a collection of various percussion items. There’s not exactly room for a percussion table, so I’ve devised a way to maximize my space while providing access to a good selection of sounds nonetheless.

In a sense this has become an instrument in itself, as demonstrated in these rather poor clips. This method of playing was used most recently on my CD, Catch the Squirrel.

Bass Drum Contraption 1.0

perc_jdbassdrum1-788338Inspired from a gig at Brews N Bytes… I liked theirs so much that I made a mental note of its construction and began shopping for parts that night when I got home.

I’ve been wanting to build a stomp board, and in fact have done some experimentation with pickups, wood and cardboard boxes (see http://www.mindspeak.com/stomp.htm), but so far I have not found the sound I was looking for.

Many old blues guys have used different types of foot stomp boxes to get a beat, but I was surprised to see that there wasn’t much info on the web about how to build the one I was using at Brews N Bytes. So here it is – possibly the first description of its kind. The bass drum is actually a cheap 10″ x 10″ tom drum from Ebay (new $10.59, but $25.54 after shipping).

The footpedal ($9.99, but with shipping $20.65) and tom mount ($6.50, but $12.49 with shipping) are also from Ebay. I used a few old screws and a couple braces from Lowe’s (maybe $3). I had the board lying around from another project. So all told, before the shipping nonsense, my investment was $30.08. It took about 30 minutes to build. The tom drum came with a couple pieces of hardware, one of which I bastardized slightly to make work for this application. Ideally I might want to just use a piece of pipe of the appropriate diameter and length, but it worked out pretty well and gave me the option of mounting something inside the drum if needed.

perc_jdbassdrum2The one at Brews N Bytes had a removable tambourine inside, but for now I just wanted the thump – so I used an old throw pillow to deaden the drum. Otherwise, the drum actually sounds pretty bad! (though I did purchase a tuning key to help tweak the sound a bit). I’m happy with the results, though it almost looks too good. My original idea was to go as cheesy and cheap as possible on this little project. So maybe I need to distress it or something. Still, this thing ROCKS on tape! Just slap an SM57 in back of this thing with some compression and you’ve got a THUD that doesn’t take up the whole room, but does give you something to work with in the mix. (Just beware that your neighbors may think you are insane stomping away at this thing too much.) Along with my brother’s old snare drum, this makes a partial kit that is nice for jamming. Future enhancements will be something non-stick for the bottom because this thing will slide if you get too vigorous with it. It also doubles as a cardiovascular workout if you are a wimpy guitarist like me.

Feel free to reference this article if you like (just give credit of course). There’s at least two guys in Australia who build stomp boards using pickups, but that has a different sound of course: http://www.jupitercreekmusic.com/stomper.html
