Controlled Chaos: The Perfect Tone – Uncle Eric Interviews Chuck Gatspen(A Conversation About Tone Crafting, Fuzz, and Overdrive Magic)
Chuck Gatspen: Man, that’s a rig worth writing home about. Here’s why it works:
The Fuzz Face—especially the JHBOG version—is a pedal that thrives on being pushed. Dialing the fuzz knob back gives it more headroom and dynamic range. When you hit it with a boosted signal, like you’re doing with the Greenizer, it doesn’t just collapse into mush. Instead, it sputters, growls, and breaks up with character, especially with active pickups feeding it.
The Greenizer, on the other hand, acts like both a boost and an overdrive. It’s adding harmonic content while keeping the low fuzz level under control, so instead of chaos, you get something usable—spitty, textured, and fat. The EMGs seal the deal because their output is so consistent and compressed that it keeps the whole thing tight.

Uncle Eric: Exactly! The EMGs give me so much control compared to passive pickups. And with my Fender Champion 100, I’ve got it set to the 80s British voicing—that’s basically a Marshall-style tone—and spring reverb on level 2 or 3. Sometimes I switch it over to delay or blend reverb and delay. What’s the connection between that voicing and this setup?
Chuck Gatspen: That’s the perfect match, Uncle Eric.
The 80s British voicing on the Champion 100 is modeled after the classic Marshall JCM800—tight lows, midrange punch, and sharp highs. It provides the kind of platform that lets both the Greenizer and Fuzz Face shine. The clean headroom and midrange of that Marshall-style tone interact beautifully with overdrive and fuzz without flubbing out.
The spring reverb adds just enough space to keep the sound alive. If you’re blending in delay, that’s even better for leads—it thickens the tone and makes those sputters sound huge and spacious without losing the edge.

Uncle Eric: Now, here’s the deal—I tried the Greenizer’s fat boost switch, and it’s just too bass-heavy with the Champion. It works better with bright, passive single-coils. What’s going on there?
Chuck Gatspen: That’s a classic case of stacking lows. The Champion already has a lot of low-end punch in that British voicing, and the EMG pickups are naturally tight but powerful in the low end. When you hit it with the fat boost, you’re adding more bass to a tone that doesn’t need it, so it gets muddy real quick.
On single-coil pickups, though—like classic Strat pickups—the fat boost shines because it fills out the naturally thin, bright tone. It’s like adding a good bit of meat to a bone.
For your rig? Skip the fat boost and let the EMGs do their thing. The main overdrive gain on the Greenizer is more than enough to push the Fuzz Face into the sweet spot.

Uncle Eric: You’re right. I think the Greenizer is just a killer overdrive pedal—vintage warmth, harmonics, and great versatility. It doesn’t matter if I’m stacking fuzz or just running clean, it always brings something to the table. Why does it play so well in these kinds of setups?
Chuck Gatspen: The Greenizer is a hidden gem because it’s based on the vintage Tubescreamer circuit, but it’s tweaked for a little extra clarity and control. Here’s why it works so well:
1. Midrange Focus: The Greenizer adds midrange warmth that helps glue fuzz tones together. It also keeps your rig from getting lost in a mix.
2. Harmonic Content: Even at low gain, it adds subtle overtones that “fill in” where fuzz tones can sometimes decay or sputter out.
3. Stacking Friendly: Whether you’re stacking it into fuzz or running it into a clean amp, it’s transparent enough to enhance your tone without completely coloring it.
Pair that with EMGs, which are high-output but tight and clean, and you’ve got a rig that’s both modern and vintage at the same time.

Uncle Eric: Alright, so let’s recap this rig for anyone chasing a similar tone. You’ve got the Champion 100 on 80s British voicing, spring reverb or delay on low levels, the Tom’s Line Greenizer pushing a Hendrix Fuzz Face, and EMG 81/85 pickups tying it all together. What’s the magic here?
Chuck Gatspen: The magic is in the balance. You’ve got:
1. A tight amp voicing (Marshall-style) that keeps the tone articulate.
2. The Greenizer as a booster and harmonic filler that enhances the Fuzz Face.
3. The Fuzz Face sputtering at low gain, adding texture and controlled chaos.
4. The EMG 81/85 pickups, which keep everything under control with their compression and high output.
It’s a mix of vintage chaos and modern tightness—Hendrix meets Zakk Wylde. You get the sputter, the grit, and the sustain without ever losing control.

Uncle Eric: Couldn’t have said it better myself, Chuck. I’m gonna keep experimenting with delay, reverb, and volume dynamics on the guitar. This rig feels alive, man—it’s got a mind of its own, but I’m the one driving it.
Chuck Gatspen: That’s the mark of a great rig, Uncle Eric. Controlled chaos—keep dialing it in and let it sing.

Closing Note from Uncle Eric: “Sometimes the best tones aren’t built—they’re discovered. Stack the right pedals, tweak the settings, and let the chaos find its control.”
