Over a month ago I have posted few words about some sort of invention in the DIY stomp box world.
The idea was simple so genius: Using the p-bass pickups as a sound transformer.
The majority of the DIY stomp boxes I saw so far has a piezo buzzer for this goal.
And as any piezo element it comes with 2 common issues:
1. “Dirtiness” of the sound. Not only the kick of you foot is transmitted but all possible squicks and even smallest rustles.
2. Huge feedback. You have to be a sound engineering guru to get an acceptable sound. So it is loud enough and without the self-generated feedback sound.
The regular magnetic pickup supposes to solve both problems at least the big part of it.
Just because it’s only able to transmit the vibrations of the metal object.
In the case of the guitar it is the vibration of the string. But you can use any metal object for this goal.
Now. Why p-bass pickup?
Well our DIY stomp box is a foot drum, right?
Therefore we want to get as low frequency of the drum sound as possible.
MATERIALS USED IN THE PROJECT:
|1. Cohiba cigar box..
At the beginning I was thinking about the bigger box as I saw in the internet and described in the blog article.
But finally I have decided on this one.
Main reason – the portability.
|2. P-bass pickups.
The cheapest solution was to order the set of p-bass pickups on eBay.
Its price was just $6.50 to the moment of ordering from (surprise!) China shipping free.
The first test showed the significant electric feedback.
Well that’s the price of the low price I guess.
Therefore I had to add the item 3:
|3. Self-adhesive aluminium coil.
The best solution for the shielding of the box would be a copper coil of course.
But the aluminium coil is much cheaper and still does the work.
The covering of the interior of the box will protect the pickups from the electromagnetic interference and thus will decrease the unpleasant sound.
|4. 1/4″ Guitar/Phone Jack.
This is a standard part for any DIY project.
You have to have a plug to connect the amplifier cable. Right?
The only relatively complex job in this project is the soldering the pickup wires to this jack.
You can buy them in any store electric department just for $0.7 or 10 pieces for $6 or so.
Make sure to sand a bit the contacts before soldering.
|5. Self Adhesive Double 2 Sided Sticky Strong Mounting Tape.
Of course, you can use the screws or glue to mount the parts inside the cigar box.
I’ve found for myself that this mounting tape is the best solution.
Just be patient and don’t rush to remove the protecting paper from the other side until you sure all stripes are in place and ready to catch the item.
|6. String Replacing Metal Object.
Remember that we need some metal object vibrating on the foot hits?
After some thoughtful search in the recycling bin I’ve made my decision on the Fisherman’s Friend metal box for the lozenges. I’ve ruthlessly detached the lid and that’s what I will use as a “string”.
That’s actually it.
You are pretty much done.
I also would advise to put some rubber legs on the bottom so it will not slide while in use.
Some people put the bigger/higher legs on the outer side so the box is comfortably inclined towards to your foot.
But it really depends on personal preferences.
I personally use the roll of the soft carpet.
The demo video is to come shortly.
