Rare and special-edition effects units

In addition to our best-selling HotBoxes and popular boutique effects units sometimes SeanMandrake makes a few special editions, one-offs and unusual pieces of kit. These effects are offered strictly on a first-come first-served basis and are always hand-wired and unique.

Volume Boxes

Many amplifiers are designed so that their built-in volume controls change the tone as they are turned up. The Marshall JCM800, as just one example, is designed to get warmer and less harsh as you turn the volume control and this means that the only way to get that warm tone is to have the control at full.

Nearly all valve amps also use cascaded gain stages and the volume control is often in the middle of this. This means that unless you turn the volume right up on the amp the pre-amp valves don't interact and you end up stuck with a one-sound amp that quickly goes from too-clean to too-grotty and only has one sweet spot.

With a volume box after your pedals and before your amp you get more control and more tone from your amplifier. No magic. No fuss. Just better tone and more control. It really is that simple.

F258 Drive : Vintage Overdrive.

At the heart of the F258 are three hand-selected vintage Germanium diodes that form an asymmetric overdrive circuit. Around this is a carefully designed tone-network that shapes the drive into a sweetly vicious growl reminiscent of an era when tube amps were pushed to their limits, transformers got hot and every gig could be your last.
