When you make DIY stompboxes powered by 9-volt batteries, your biggest fear is a solder burn (or dropping your drill on your iPad, but that’s another story). DIY amps are different: AC voltage can kill you, so a klutz like me approaches amp builds with caution.
Which brings me to one of the great things about Tube Depot’s Tweed Champ Vacuum Tube Amp Kit: the fantastic assembly manual. Other great things include the price ($499, roughly half the price of a non-kit Champ clone of comparable quality). The design (which follows the original circuit, but substitutes an intelligently designed circuit board layout for the original turret board). And most of all, the tone.
I’ve got lots more to say about the kit, the fun I had building it, the lore of the 5-watt ’58 Champ, and the pros and cons of Class A amps (the Champ is the only Fender classic that merits the classification). But first, have a listen!
