Attention guitar amp designers... techs... players... tone tweakers!

MultiChoke
Introducing the first variable choke!

 Mercury's NEW MultiChoke offers you these important benefits:

Think of a choke as a shock-absorber for your amp's power transformer. Did you know that upgrading your tired old or wimpy reissue stock choke -- or adding a Mercury choke to an amplifier that doesn't have one* -- will actually extend the life of your power transformer and rectifier?

*Amp manufacturers often cut costs by the use of a resistor in place of a choke. This choice has absolutely nothing to do with tone, it's purely economic. Replacing that resistor with a choke is a low-cost upgrade that'll usually give you a huge improvement in tone.

Your amp's tone noticeably improves with any peaked and tweaked, hand-tuned choke from Mercury. Mercury users tell us that they hear a tonal richness that was not there before adding one of our chokes. Why? Because a choke provides musical smoothing to your amp's circuit. It also has a huge impact on touch-sensitivity and tone dynamics.

A choke is so much more than a simple inductor. It can also store energy like a capacitor. Better voltage regulation results from using premium-quality chokes. The choke puts less stress on your power transformer and permits higher load currents to be drawn from vacuum tube rectifiers without exceeding their peak current rating. This means life extension for your tube rectifier -- and even solid-state rectifiers run happier!

Mercury's NEW MultiChoke is in a league by itself. The MultiChoke allows you to quickly and easily audition several different choke values to determine the best possible fine-tube the tone from your amp. And, the MultiChoke saves time and money by eliminating the need to purchase a stack of single-value chokes -- not to mention all of the added time needed to solder/de-solder leads for your tests.

Depending upon your needs, Mercury offers several MultiChokes with varying value sets. Currently available sets include:
