It's mean... it's nasty... it's now 13 watts. Mercury's Mean 13 High-Power Upgrade is a total balls-out approach to modifying your Little Giant. A complete redesign of the original amp that delivers a whole new spectrum of T-O-N-E -- from classic American to classic British distortion! Awesome tone with stone-quiet performance, for a fraction of the cost of anything in its price range!

MEAN 13 HIGH-POWER Upgrade -- total balls-out upgrade with twin 6V6 tubes. And 13 watts output, too! This ain't yer momma's "Little Giant" any more!

The Mean 13 High-Power Upgrade is a completely different design than our XLG Upgrade Kit. The Mean 13 High-Power Upgrade requires a radical modification of the Little Giant's circuit board and chassis -- including the addition of twin-6V6 sockets and it's full-custom transformers and choke.

More than any other component, your amp's transformers determine its tone. Our Mean 13 High-Power Upgrade features custom-designed, handmade and tuned, performance transformers. The same or higher quality as those used in boutique amps costing substantially more. And, like all of our upgrades, after you hear this you'll never settle for stock transformers again. Never. The improvement in tone is beyond dramatic!

PLEASE NOTE: This is a specially developed and priced kit. At this time we are not selling the components individually. THESE KITS ARE AVAILABLE IN THE USA/CANADA 120V VERSIONS ONLY. AT THIS TIME THERE IS NO EXPORT VERSION.

*BIG NOTE: The Blackheart Mean 13 Mercury's kit does not include the amplifier -- only the components necessary for the upgrade of an existing amp.

CAUTION! The voltages in your amplifier can be dangerous. Transformers and chokes are not user serviceable parts. Installation of these components should always be performed by an experienced technician. The simple ability to use a soldering iron is not enough to qualify a "do it yourself person." Those who are inexperienced in working with electronic circuits should never attempt to service their amplifier. Household line currents can be deadly!! Transformers, chokes and large filter capacitors can store a dangerous charge for several days or more after the amplifier has been unplugged. Never touch the terminals of such devices without being certain of their charge status. Risk of shock and damage to equipment may result from mishandling and/or improper use of these components. Please use common sense and always think safety first. After all, tone is most enjoyed when you are alive to hear it.
