Emperor Dual Overdrive

Who doesn't love a Blues Breaker? What about a highly modified BB with magic beans for diodes and some fine tweaking to make it oh-so-sweet? Now put two in a box and hold on tight.

Y'all know what this is based on so no need to go into too much detail. We've board-mounted everything but the jacks and DC socket on this to make it as neat as can be.

There's a lot of debate on how integral the 'magic' diodes are to the sound of these circuits, and it's really down to personal taste. They are quite expensive, so we're making them optional and will supply 1N4148 if you don't go for them. You can experiment with your own combinations rather than the original's MA856/1S1588 combination.

There's an optional 18V charge pump on board, and both circuits can be individually switched for 9 or 18V operation for more/less headroom. You can have mini slide switches or header pins/jumpers to select the voltage, or leave the charge pump out altogether if you prefer.

The original has internal trimmers for presence control, but we've given you the option to have these as external pots. It makes enough of a difference to make the extra knobs worthwhile in our opinion. These extra pots mean we've had to venture away from the control layout of the original a little. If you go for an 8-pot layout, all good. If you want trimmers for the presence controls your Tone pots are going to be towards the edge of the box rather than centered below your Gain and Vol. You do have the option of bending the Tone pot legs out of the way and wiring them to the PCB if you really want to centre them up - no harm done. Please choose the correct enclosure option. Type A for all pots external, Type B for internal Presence and board mounted Tone pots, Type C if you don't mind bending Tone pot legs and wiring them up.

Designed for vertical mount pots (round shafts) which are highly recommended, or you can wire up normal pots (with splined shafts) if you prefer. Pre-built option is only available with vertical mount.

Oh, and you can choose between normal True Bypass with 3PDT footswitches, or go for the daughterboard with our OptoPuss optical switching and those slightly softer DPDT footswitches. The switches mount on a separate daughterboard that neatly connects to the main PCB via header pins.

All this AND we've left enough space for a battery.

Please be aware that this kit requires quite precise enclosure drilling if you're attempting it yourself. We're supplying Lumberg KLB series jacks to make it easier to fit everything in.

Kit includes: PCBs, all components, hook-up wire, your choice of footswitches, Lumberg jack sockets, DC socket, battery snap, LEDs, Connecting pins. Enclosure (pre-drilled) is optional and will take a battery. Does not include knobs.

Difficulty: Semi-hard

PCB sizes: 100 x 47 / 100 x 29

Knobs required: 6 / 8
