Cornell - Explorer 10 Amp Head
Take it from the top
A small, deceptively versatile tone monster that makes a great recording tool, the Explorer 10 is an exceptional amplifier. Don't let the modern looks, the blue LEDs and all that jazz distract from the fact that this is an old-school, single-ended class A valve amplifier. It is a lunchbox-style class A valve amplifier that's housed in a typically rugged grey steel case, with perforated cover and smart gold handle trims. It's a stylish little amp, and reassuringly heavy, too, with over-sized mains and output transformers under the hood. The electronics are hand-soldered onto a substantial circuit board, 4.8mm thick, that's arranged with printed tracks with turret and eyelet-style wiring – much like you might see in 1950s American amplifiers. You'll find the base for the Explorer's sole 6L6 power valve housed on the main board, with the two 12 preamp valve bases mounted on the chassis with hand-wired links. As you might expect by now, the components are of the highest order, and audio geeks will be sent to their happy place upon witnessing the primo carbon comp resistors and flawless wiring. The Explorer 10's setup is simple. It has a single-channel preamp with volume, gain and tone rotary controls. There’s a Clean/Mean switch that adds a respectable mid-boost, and a four-way attenuator switch to control the Explorer 10’s output power from 10 watts down to a measly 1/8 watt. It also broadens your single coil tone. On the rear of the amp you'll find a pair of speaker outputs and an impedance switch with a choice of four- or eight-ohm loads, so you won't be lacking in cabinet options. Upon switching the amp on you are greeted with four blue LEDs lighting up the preamp valves. There is no standby; a smart thermistor solution delays the full current en route to the mains transformer until said thermistor has warmed up. Although the Explorer 10 is a simple amplifier, there is plenty of variety on offer here. There's no shortage of brightness, but none of those ice-pick tones to set your teeth – and playing – on edge. Whether you are noodling some Montgomery lines on the LP's neck pickup or playing sharp, compressed country on the Strat, the Explorer's cleans are incredibly musical.
Denis Cornell is one of the most revered names in British guitar amplification. He was among those responsible for Sound City amplifiers and the Fuzz Face, back when he was making his bones at Arbiter. He counts the likes of Eric Clapton and Noel Gallagher as his fans, and anyone who is familiar with his work can attest to the super-tough build quality and attention to detail.
Rotary Wattage Select Switch
Whether you're in the studio or playing at home, the wattage selection allows you to choose how powerful you want the amp to be. This means you can select a lower wattage and drive the amp harder however the overall volume being much lower - making it more suitable for home use!Here are the available wattages:A - 10 wattsB - 2.5 wattsC - 0.25 wattD - 0.08 watt
Loudspeaker Outlets & Impedance Switch
On the back of the head, there’s a pair of loudspeaker outlets and an impedance switch with a choice of four- or eight-ohm loads, for easy connection to a wide range of cabinets.
Robust Construction To Last A Lifetime
There’s no standby switch, but the Explorer 10 uses a clever thermistor arrangement to delay full current being applied to the mains transformer for a few seconds until the thermistor has warmed up. Overall, the Cornell is built to the kind of standard only a few manufacturers can match and should last a lifetime.LEDs also light up the preamp valves when you switch on. CLEAN & MEAN SWITCHThe Explorer 10 has a simple single-channel preamp with volume, gain and tone rotary controls. There’s a switch called Clean/Mean, which adds a respectable midboost. it acts as a hefty boost to the mids – just the thing when you need a little more punch.
