Set ‘em Up
Digging in, the first thing that caught my eye was the Celestion Vintage 30 speaker, which carries an 8-ohm rating. The tube compliment is also impressive: two EL34s and three 12AX7s. Usually in a 30-watt amp we’d expect to see EL84 type tubes, but the EL34 is less noisy and has a better life expectancy. The amp is cathode biased, rather than fixed bias, which is partly responsible for the lower wattage it produces (Cornford’s 50-watt version is fixed bias, and carries the same tube compliment).
Starting left on the control panel, we have the Input jack, which is 1 megohm, optimal for electric guitar usage. Next is Gain, a small toggle switch for activating the Boost feature, the Boost control, and Bass, Middle and Treble tone controls. This is followed by the Send and Return jacks for the effects loop, and the Master Volume control and On/Off/Standby switch.
The rear panel features an IEC-type mains inlet socket, high-tension fuse holder, and 5speaker jacks: one 16-ohm, two 8-ohm and two 4-ohm loads. I have always preferred this type of impedance switching, as opposed to the rotary or switch type. Direct connection to the transformer taps is more reliable. At the end of the back panel is the footswitch jack for the one-button Boost switch, which is provided with the amp. It overrides the switch on the front panel.
Knock ‘em Down
I have to say I was pleasantly surprised when I first fired up the amp. I always start with Tone and Gain controls all on twelve o’clock. I used my trusty Les Paul Custom with original ‘50s PAF pickups first. The tone was warm and very bluesy, reminiscent of very early Clapton tone with a sweet, smooth overdrive and just the right amount of harmonics. I had discovered a killer blues amp and I hadn’t even turned a knob yet. The tone controls sweep through a wide range, much like other Cornford amps I’ve played, and it was easy to dial in the tones I wanted.
