E - Snare drum project

My E snare project really began with a view to simply expanding my Roland kit by way of an additional cymbal.
I looked at the cost of additional cymbals and decided that I could probably make one cheaper. So, as I always used to practise on a rubber pad on my acoustic cymbal I decided to see if I could modify this. I purchased a 27mm piezo and a stereo cable from Amazon for the total cost of around £3.90. I then soldered the piezo to the stereo cable (simple job) and stuck the piezo to the back of the rubber pad. I set up my acoustic ride cymbal in the correct position, placed the rubber pad on top, plugged in the jack and…….. it worked!
The rubber pad mutes the noise from the cymbal and, for me anyway, it’s nice to have that element of ‘real kit’ amongst all the pads and plastic cymbals.
The low cost of this addition and relative ease of making it got me looking at other mods online.

So, I decided I needed another ‘drum’ to hit and planned to build a splitter cable and go all the way by converting my acoustic snare drum to an ‘E-Snare’. The idea being that I could split ‘head’ and ‘rim’ on my dual trigger snare and assign any sound to it (another tom was the plan).I found a ‘how to’ guide online with instructions how to wire up a splitter. I ordered a male stereo to two female stereo splitter cable. I wanted it to look neat and managed to solder the much needed resistor (yes, it really does need this) into the jack end without it looking a mess.

It’s probably here that I should point out that they accept no responsibility for any damage to your module (or any other part of your kit) if you try this.

Next came researching how to convert my acoustic snare to an E-snare. This was quite an eye opener and I learnt a lot about how triggers work and various methods of mounting them. I decided to go for a relatively simple technique of bridging between two opposite lugs and mounting my piezo centrally. I do have previous engineering experience so making up a couple of brackets and necessary parts wasn’t too much of a task. I decided to use a thin wooden batten to span the gap. The tricky part is getting the piezo to sit at the correct height as it needs a ‘cone’ to trigger correctly. The most difficult part for me was sourcing the correct type of foam to make a cone. I eventually used a yoga block (Argos) which I cut down to around 40mm x 35mm. Then the fun part came. I taped the foam block onto a small sanding disc on the end of a drill and used coarse sand paper to shape it to a perfect cone. Note: the cone needs a 7mm flat top as this touches the head to trigger.

Also note: sanding this stuff creates a lot of dust – wear a mask!

Once I had my cone made I wired up my 27mm piezo (lead comes out of air hole in shell) and stuck the cone on. The top of the cone needs to protrude 2mm above the bearing edge. Easy to check using a straight edge across the drum.
I opted for a remo mesh head which was around £17. Plugged into the splitter and everything worked.

For a few days…..

Then ‘mis triggering’ started. To cut a very long story short my dual trigger snare no longer ‘dual triggers’. Whether this is due to using the splitter cable which has fried something on the pad or whether it’s age (6 years old), or whether it’s just coincidence, I’m not too sure.

What I do know is that there’s an ongoing debate about whether electronic kits will surpass acoustic kits. You either love them or hate them. I’m kind of torn at present as I think both have their place. With my Roland kit I can play anytime, teach more easily and record simply. My acoustic kit is noisy, big, looks fantastic and at least the sounds I’m making are from the actual sticks / brushes on the drums and cymbals and not some pre-recorded samples that I’m just triggering.

From my recent experiences I can safely say that I wouldn’t convert anymore drums. The mesh heads are good, very quiet, but very bouncy. I read beforehand that a lot of drummers were of this opinion but I think you need to try it for yourself. So, in conclusion, if anybody has read this far and wants my help I’m happy to email photos and measurements etc so you can try for yourself.

But in my opinion, don’t waste your time.
