The aim of the operation was to transform this beautiful toaster racing machine by giving it an AC15 preamp and grafting it to the Top boost AC30. Along the way, I thought "why not to add a second master volume and let's crazy, an effects loop??". All that retaining the original cosmetically, of course ...

And here is the result ....

• The controls for gain, treble and bass remain unchanged,
• The "Mid" becomes the "Cut",
• The switch "bright / tick" becomes "gain + / -",
• Adding a second volume knob and an LED indicating the commissioning of the "master 2",Adding an additional tube
• .
