If you have a mic, great if not, Supro has provided a very respectable line-out for sending your signal direct. There’s no onboard reverb, which might make some players consider its larger 1x10 5W sibling, but it’ll take a reverb pedal nicely, and throwing a little overdrive or fuzz in front of it will do a great job of provoking its more animalistic side. What it lacks in headroom, it makes up for in the sweetness of its cleans.

The control panel has a volume knob, a boost toggle switch, tone and master volume controls, plus your standby and power switches. The Delta King 8 has a single 8” speaker that’s driven by a single 12AU7 power tube, with a footswitchable FET boost for an extra ladle of gain. However, at a single-watt, it gives up that rabble-rousing gain at manageable volumes, and as such makes an ideal roommate. Indulge in analog with the best tube ampsįeaturing a similar retro aesthetic to Supro’s Blues King 12, albeit with go-faster racing stripes, the Delta King 8 is a single-channel Class A tube combo that’s all teeth, grit and heat.It helps, of course, that the tones are bang-on, but the black vinyl covering and logically arranged control panel will assist many an analogue native in acclimatising to this new world of digital amplification. This is all very 21st century, but the Spark retains the classic feel of a guitar amplifier. Bored of the metronome? The Smart Jam feature will create a backing track for you to play along to – just pick a tempo, play a riff, select a genre and the amp and app will do the rest. That’s invaluable as a practise tool, but it also gives you a helping hand in learning to work out songs by ear.
But if you don’t know the chords, the Auto Chords feature on the Spark app will transcribe them for you. Sure, you can stream your favourite songs and play along – that’s a given.

Having solved the age-old conundrum of how to deliver inspiring tones at household volumes – the Spark’s twin 4” speakers offering a very respectable full stereo spread for a small combo amp – it then offers a digital solution for those times when you have no one to accompany you. Yes, it’s a housetrained tube amp with a super-simple setup, and if you want something small and manageable but can’t get inspired without that genuine tube heat, this is where the action’s at. The Supro Delta King 8 provides a heady dose of electric blues and early rock ’n’ roll mojo, and all from a diminutive 1x8 format whose single watt of output will be enough to raise the hairs on the back of your neck without waking up the whole street. Best of all, though, it sounds incredible, with heaps of amp and effects models to play with.

These two types of modulation are Amplitude Modulation (AM) and Frequency Modulation (FM).What makes ’em small? Well, they’re portable and lightweight, they sound good at low volumes, and they don’t take up much space. The transmitter sends radio signals-called continuous sine waves-using one of two types of modulation to carry information. Analog radio has two main parts, a receiver and a transmitter. The technology itself is remarkably simple. In fact, a lot of vintage gear is still in use. And in all honesty, not much has changed since Tesla's first "modern" radio. Although fierce rivals, the impact of Marconi and Tesla lead to the use of analog radio as we know it today. While radio broadcasting grew in popularity through the 1920s, it took years of legal battles for Nikola Tesla to be finally awarded the US patent posthumously in 1943. Guglielmo Marconi is credited with the first successful application of wireless technology after sending out the first radio signal-consisting of a single letter, "S"-in 1895. That way, you can understand the difference between analog and digital radio, and why it's a good idea to make the change.Īnalog radio obviously isn't a new technology.
In order to learn about digital radio, you first need to learn how analog radio works.
