So I've been reading this forum for a good while, and I've noticed a couple things. First off, the main complaint you might hear about dirt pedals is that they cut low end. I think everyone's dealt with that. Second, tons of people play solid state amps, and if they do play a tube amp, they've usually got the volume set at like 9 o'clock. What the hell? Of course I've done a few soundclips of some dirt pedals, a lot of which I can easily get tons of low end out of, but other players who buy the same pedals can't. I guess I took it for granted that everyone knew what I'm about to explain, but it's become more and more clear to me that they don't so let me tell you why: It's simple. Compression. This is a big part of the reason why tube amps pushed to their breaking point sound so good and get so loud, and not something that the guy running his super high wattage tube amp at 9 o'clock is necessarily going to get. Many tube amps are very responsive and dynamic in that you can control with your attack how much of that tube saturation and magic you get. But with a tube amp cranked to it's breaking point, you don't always get twice as loud when you play twice as hard. That's because of the compression. The sound just gets bigger, and you get more sustain because the more you dig in, the more the amp compresses. I get huge low end out of Tonebenders (Mk II and III), Fuzz Faces, Tone Machines, my Maestro Fuzz Tone, and other such fuzzes, none of them modded for bass. The reason is simple, I run the volume high on the pedal. My amps, which I run at the breaking point, will clamp down (compress) on the overall volume so I don't get a volume boost actually, the added upper content from the volume boost gets compressed but squeezes more of that tube amp magic out, and the low frequencies just fill out the sound on any dirtbox that doesn't totally delete the low frequencies. Upping the volume is just like playing harder on a cranked tube amp, the sound gets bigger, but not always louder. If I can get time tomorrow I'll do some on/off clips to demonstrate this. Needless to say this is one of the reasons I've been playing only low wattage tube amps in my new band that I can actually crank into compression. I NEED classic 60's fuzz AND low end to fill out my three piece. And that is how I can have both.
