The God of Mods – Dennis Kager


The God of Mods: The Tone King Gives a Shout to Dennis Kager

 Marc Johnson for The Tone King

Without the support of some, would not be doing as well as it is today, and Dennis Kager has been one of our biggest supporters. For followers of TTK, you will recognize Dennis’ handiwork from our vid “TTK’s Modded JCA20H”, where we demoed the Jet City amp modded by Dennis to include a boost as well as an effects loop.

The thing that sets Dennis apart from a lot of the other Amp techs is that he is a player, and it shows in his work. Every one of his mods doesn’t try to change the character of the amp but, instead, emphasizes its best features.

After getting his education at Middlesex County Electronics School, he went straight to work for Ampeg in ’64. While he was working at Ampeg designing amps, he was working hard at night out of his home repairing them. It wasn’t long before every band passing through the Jersey area was banging down his door for repairs and modifications, and it wasn’t long after that that, with so much work, he had to leave Ampeg to do his own thing.

Calling his company Dennis Electronics, his company soon became the New York service center for both Fender and Gibson. While working on amps for big names from The Police to The Allman Brothers, Dennis still somehow found time to create the first ‘discreet’ channel-switching amp, which included two completely separate channels instead of just stacking gain on top of the clean channel. Later, he sold his line of amps and set up shop at Lou Rose Music where he has been working on amps ever since.

Any real player will tell you that nothing sounds better than a modded amp done by someone who knows what they’re doing. Dennis Kager not only knows what he is doing, but he is one of the best in the biz. His is still the go-to guy, and, when other guys can’t get the job done, they send it to him. Dennis is always open to special projects. So, if you want a killer mod done to your amp, give him a call, and don’t forget to tell him that The Tone King sent you!

About the Author: Marc published his first novel Becoming in 2010. It’s a kick-ass book with monsters and dreams and stuff, and you should buy it. Since then, he’s written thousands of articles for, many of which have been picked up for circulation by manufacturers and other news outlets. His next book, Drugs and Pancakes, should be available early 2014 if his alcoholic editor can find time to work on it in-between destroying his liver and screaming about punctuation. He graduated from Roosevelt University with honors, which means that he’s not as dumb as he looks. He’s been playing guitar for over 25 years, which is almost twice as long as most of his students have been alive.

    Hello, I recently bought an early ’72 Fender some, it was road worn and put away wet! Anyway, I want to restore this dog…We take it apart and find repair stickers in the chassis from a Dennis Electronics…I call the original owner and asked if what repairs he had in the last 40 years..He told me that he used to bring his amp to a shop in Jersey back in the 70’s..see where this is goin’? Anyway, I hope the GOTM’s breathed some magic on this wretched amp so many years ago…

    I’ve tried a bunch of different ways of sequencing my pedals, some of which are pretty straight forward, but others kills the tone a bit.

    Could you please give me a suggestion!

    Here are my pedals:

    Chromatic Tuner
    Goodrich Volume Control
    Boss NS2 Noise Supressor
    DOD 440 Envelope Filter
    Boss GE-7 Equalizer
    EXH Double Muff
    MXR Carbon Copy Analog Delay
    Digitech Whammy WH4
    EHX Memory Man

    Many thanks,

    Thanks mr Kager for Pignose G40V (he was the designer of this little beast). I get it slightly used for only 300$ (I’m not kidding). Then I’ve upgraded the speaker to neodim one, made it 2-channel foot-switchable with only pairing of master/volume knobs and relay-switching between them :), added the tone shift and many other Steve Ahola little mods from ProManiac mod-list, and now it’s more than versatile combo. My friends don’t believe such a little box has so many power and so great tube tone (clean is bright, and distorted sound with EMG81 goes almost Zakk Wylde huge)… I heard about other mr Kager amps – they are even more versatile then my modded one, and little/toneful/powerful/affordable as well, so… Best wishes to Dennis Kager.
