  • Super Bass vs JCM 800
    Sep 1 2022

    Marshall amplifiers. The sound of Rock n’ Roll? At the very least, we can certainly say that Marshall has played an important role in defining the sound of the electric guitar, and especially rock guitar. 

    In this episode, we are looking at two of Marshall’s most classic amplifiers, from about a decade apart. The first captured the sound of classic rock in the late 60’s and 70’s. The second helped spawn the next generation of 80’s hard rock, metal, and beyond.  

    The first is the towering titan that is the “plexi” amp. In this case, it’s a Metal Panel Super Bass 100 from 1973. Generally, a “plexi” Marshall is considered to be Non-Master Volume amp with 4 bridgeable inputs. 

    The second amp is the venerable JCM 800. This one is the Single Channel 50 Watt Model from 1984. In head form it is called the Model 2204. This one is a combo Model 4010. 

    The general understanding is that the earlier amps were lower gain and were a bit more versatile, while the later JCM800’s were higher gain and a bit of a one-trick pony. We put these notions, and others to the test, sampling everything from clean tones, to crunch, to cranked up devastation. We think you will find the results interesting.

  • Tweed vs Brownface vs Blackface
    Mar 9 2022

    What is more classic than a Blackface Fender Amp? A Tweed Fender Amp perhaps? What about the Brown Fenders, which are experiencing a renaissance in popularity?  

    Few amp companies have more than one classic amplifier design. Incredibly, Fender has at least a dozen classic amps, and three entirely distinct era’s; each unique both sonically and aesthetically.

    Today we are diving deep into each of these classic amplifier eras (with apologies to the Silverface era, which we consider to be mostly similar sonically to the Blackface amps- see our Blackface vs Silverface Episode), to discover what makes each one distinctive, and learn the strengths and weaknesses of each. We have a low/mid powered example from each era, and a lot of ground to cover. 

    Think Tweed amps can only do raunchy overdrive? Think Blackface amps are scooped and overly bright? Press play and prepare to open your ears and your mind.

  • Amp vs Speaker
    Dec 23 2021


    How many amps do you need to own to get all the sounds in your head? For some of us, that answer could be many. But what if the biggest difference between amps was not in fact the amps themselves, but the types of speakers and cabinets that were used? Also, if you own a bunch of amp heads, but run them all through the same speaker cabinet, will they end up sounding quite similar?

    Well, these are the questions we are tackling today. We will compare 3 classic combo amps, each through their own cab/speaker, and then start swapping cabs/speakers to see whether it is in fact the amp itself, or the cabinet that makes the most difference. 

    To be clear, you cannot make a high gain metal amp sound like a 70’s Silverface by swapping speakers. We are talking about relatively similar styles of amps here, however, this is especially useful if you have ever wondered if you need a Deluxe Reverb and an AC15, or a Marshall and an Orange.

    Speakers are probably one of the most overlooked elements of the tonal signal path (at least here at the Ground Wire). Many guitarists will change pickups, overdrive pedals, and even cables, before considering a speaker swap. Have a listen, and let us know what you think. We found the results to be rather surprising.

  • Three Pillars of Fuzz
    Nov 8 2021

    Welcome to season 2 of the Ground Wire Podcast. We're kicking off with the Three Pillars of Fuzz. Most modern fuzz pedal circuits are based, at some level, on one of three iconic fuzz designs: the Tonebender, Fuzz Face, and Big Muff Pi (nevermind that the very first fuzz design was the Maestro Fuzz Tone, and that it inspired the Tone Bender, which inspired the Fuzz Face… that is the subject of a whole other podcast) which all sound very different, and are each responsible for some majorly iconic tones.

    From Hendrix to Page, Ronno to Gilmour, Corgan to Mascis, these Fuzz designs have created the sonic foundation for some of our favorite music. So let’s dive deep, in true Ground WIre fashion. We are comparing these fuzzes, into small, medium, and high powered amps, with various guitars, and seeing how they stack with other pedals. We put each one into, and out of, it’s comfort zone. We also compare them in a band mix with bass and drums.

    Hopefully this episode will provide some insight on the merits of each, and help you determine which fit your playing style, and for which applications. Now let’s get fuzzy…
