Anyway, when the amp arrived I gave her an inspection, clean-up and retube with a set of new JJ tubes. She was now ready to be fired-up. So, I took my guitar, plugged it into the now gleaming Champ and clicked the power switch on. As the amp warmed up she began to hum. A little more mains hum than I would expect but perhaps that could be rectified (pun not intentional) later. At least there were no sparks or smoke. Everything seemed to be in order so far. But then, after a fair bit of noodling around on my old Strat, it began to dawn on me that I was not at all impressed by the tone of either the clean or overdrive channels. No, not impressed at all. Now, I’ve owned several Fender amps in my time, Twin Reverbs, Deluxe Reverbs and currently my go to amp is a Fender 1 x 12 ‘Tweed’. All these vintage models are beautiful sounding guitar amps and I have a great deal of respect for Leo Fender’s work, but this Champ 12 sounded weak and pale in comparision.
