If it’s just for quiet practice at home then a smaller, less powerful (and usually cheaper) amp will do the trick. Any kit will connect with any amp so keep your options open.Ĭonsider when you might use the monitor and in what situations. E-drum brands such as Roland and Alesis produce their own speaker systems but it’s not necessary to match brands unless you really want to. How much power does my e-kit amp need?ĭo you know your woofers from your tweeters? The fundamental factors that set these amps apart from each other are how much power they can produce (measured in watts), connectivity options in terms of inputs and outputs and whether the system delivers mono or stereo sound. Monitors which have been designed specifically for e-drums will more faithfully reproduce these desired frequencies.

Headphones are the go-to option for convenience and quiet e-drum practice, but where does that leave us when we want to jam with other musicians or show off our new chops to whoever may care to listen? Sometimes it just feels better to move some air and feel the punch of the drums as nature intended. If you're unsure about whether the readings seem off, Google for the diode type and expected readings.Īfter soldering, make sure you cut lead ends and clear away anything on the underside of the turret board.(Image credit: Roland) What should I look for in an electronic drum amp? Your DMM should have a clearly-marked diode check function which you can use to verify them. We opted for a 12AX7 in the pre and an EL84 in the power section, which are both quite small and seemingly fragile valves, but with a gentle push they seated correctly.ĭiodes are particularly heat-sensitive, so it's worth checking them both before they go into circuit and after. However, be careful to not force anything and cause damage. When it comes to actually seating the valves, some wiggling into place will be required, especially the first time the sockets are used. Writing the pin numbers in permanent marker on the inside of the chassis by the sockets will avoid silly mistakes when wiring up the connections. We accidentally placed our valve sockets at the wrong angle when compared to the schematic, and so had to work out which connections were correct. If you've experimented with hobbyist electronics before then you'll probably know that even 9V DC is more than enough to melt a component and start a small fire, so the voltage in itself isn't the real danger, carelessness is. This is not an optional step - amp voltages can kill you, but with due care and attention, the risks are small.

So, first things first - if you're going to be undertaking an amp build then look online for advice on how to work safely with high voltages. We're getting ahead of ourselves though - on to the build. The N5X that we've chosen is a British-voiced, single-ended five watt head with a useful variable voltage circuit to bring the amp down from its surprisingly beefy maximum volume back to room level.Īlthough apparent volume is a fraught and somewhat subjective thing, taking a very rough rule-of-thumb of a fifty-watt amp being double the volume of a five watt amp - ignoring questions of clean headroom - five watts is more than enough power to be useful.
