The goal was to create a small tube amp, the guitar signal of which was to be as un-molested as possible. It had to have both clean and crunch channels, conveniently switchable, and it had to accomodate for an aggressive overdrive tone that didnt flub out like a poorly executed panna cotta. After at least a good year of trial and error, the W.I.S.C emerged, and it sounded pretty beastly for such a simple little guy. Wolf In Sheep's Clothing describes this wee amp well as it produces a far greater tone than you would expect. This Plan Pack contains the circuit schematic, layout diagram, chassis footprint, parts list, component codes and turret board layout; all the information you need to construct this amp in your own time. If you are keen to build this amp, as an introductory offer and to say thanks to all you YouTubers out there, you can download the Plan Pack for just 1 buck.

Thanks to a chassis layout, that took what seemed like forever to complete, the W.I.S.C is pretty quiet in terms of unwanted noise. I believe the layout of an amp is perhaps the most important aspect of an amp design, almost like the ultimate mod. Ever looked at the guts of a tube amp and thought, what the? The 40's and 50's were the golden age of tidy, neat circuit building. The 60's got a little loose and by the end of the 70's, things just went pear shaped. It was as though someone grabbed a handful of electrical components, threw them at the nearest chassis, grounded whatever they could, wherever they could, and called it a done deal. The W.I.S.C layout took a bit of doing. It is as close to point-to-point as I could get it. Each tube is aligned with its corresponding filter cap and leads are as short as possible where they need to be. Via a significant earth strap, the circuit is grounded at a single location, near the Primary Transformer. The layout provides for the least amount of hum and hiss and you can really wind up the gain and be confident that your cat wont scratch your face off. Conversely, If your neighbours are sensitive folk who are likely to stone your windows after poisoning your vege patch, you can dial down the volume to civil levels.
