Josh Scott is a professional musician who has spent decades evaluating guitar equipment. When he puts his stamp on something, it carries weight in the pedal community. So when he starts demonstrating Hagerman's pedals from Honolulu, listeners pay attention.
Hagerman Amplification represents something increasingly rare in the pedal market: all-tube circuitry built with genuine vacuum tubes. Most modern pedals use solid-state components that simulate tube tone. These don't模拟 anything. They contain actual tubes—12AX7, 12AU7, EF86—and the sound reflects that authenticity.
The Compressor and Overdrive Section
The 12AU7 Compressor stands out as something different in the overdrive category. It's not chasing traditional compressor territory. Instead, it functions more like a always-on sweetener that shapes the entire signal chain rather than just taming dynamics. Players who have struggled to find the right compressor will want to pay attention here.
The 12AX7 Overdriver delivers what Scott describes as foundational overdrive tone—specifically when using neck pickup and low gain settings. The tube clipping behavior creates organic saturation that differs from typical op-amp based overdrives. The EF86 Booster represents a British AC amp preamp topology, historically associated with UK amplification circuits. It functions equally well as a mild front-end drive or can slam other pedals in the chain.
This thing is incredible—it just clears the entire signal up without making it sound bad.
The Tubeklon and Gamma Radiation
The Hagerman Tubeklon literally implements a Tube Clon Centaur circuit—a clone of the famous boutique overdrive. What distinguishes this from similar pedals is the texture on the decay of the clipping. It loses some of what the original Clone offers, but gains a different character that's really nice for certain applications.
The Gamma Radiation becomes Scott's clear favorite among these offerings. Level drive, tone, and energy create multiple tonal pathways within the same pedal. The serial number one he received personally sounds particularly special. It's described as combining Eric Johnson's tones with Dinosaur Jr.—a chunky, hungry sound that makes players want to play more.
The Acoustic Preamp
Beyond electric applications, Hagerman also sent an acoustic preamp that functions as a direct box with tube tone. Running at normal voltages, it's super portable and doesn't require the typical 9V power setup. Players wanting high-quality small tube preamps for acoustic guitars should notice this fills a gap in available options.
The Bottom Line
Hagerman's pedals represent something becoming increasingly rare: genuine all-tube construction with vacuum tubes inside each pedal. The build quality is solid, the designs are clever, and they sound fantastic. The biggest strength is that these aren't simulations—they're real tube circuits in compact pedal formats. The vulnerability? These are niche products for players who specifically want tube tone rather than transistor approximations. For everyone else, this might be exactly what the signal chain needed.
Bottom Line
The strongest argument here is simple: real tubes sound better than solid-state approximations, and Hagerman delivers that without the typical tube amp maintenance headaches. The biggest vulnerability is practical—these require more care than standard digital pedals and won't appeal to players looking for plug-and-play simplicity. But for tone enthusiasts who want authentic vacuum tube character in their effects chain, this collection from Hawaii has arrived at the right time.
