GUBEC HIGH-GAIN ENGINE

FROM FROSTBITTEN SCANDINAVIAN METAL TO SUN-SOAKED CALIFORNIA LEADS — EVERY SHADE OF HIGH-GAIN EXPRESSION.

TONAL SPECTRUM

Gubec is a high-gain engine built for true tone chasers. It covers the full spectrum of heavy expression — from the frostbitten riffs of cold, Scandinavian metal to the sun-soaked saturation of classic California leads. But can also dial a clean tone, and anything in between.

STUDIO SOUND EQ

With all comprehensive EQ, this pedal gives you surgical control over your tone. The standout is the low-mid control — carefully tuned to cut out the mud and carve space in the mix, delivering that polished, "finished" sound you usually only hear on records.

LEGENDARY AMP TONES

The high-mid control unlocks an entirely different dimension, letting you sweep from the articulate bite of a Friedman to the classic roar of a Marshall. Together, they put legendary amp tones at your feet. For both crushing riffs and soaring solos, this control shapes your tone with precision and musicality.

THREE-WAY TIGHT TOGGLE

Add to that a three-way Tight toggle switch and you've got instant access to entirely different worlds of gain:

• Wide Range – huge, open low end for stoner, doom, or fuzz-drenched riffs.
• Tight – razor-sharp response for fast, palm-muted chugs and modern metal precision.
• 720Hz Focus – a classic midrange filter inspired by the legendary Tube Screamer.

VERSITILE TONE AUTHORITY

From blackened north to golden south, Gubec adapts to every shade of high-gain playing — with the clarity, punch, and authority of a fully produced record.

TL072 Dual JFET Op-Amp — Core Gain and Signal Definition

The TL072 dual JFET op-amp forms the main amplification stage, selected for its low input bias, high input impedance, and wide bandwidth. It provides clean, high-gain amplification with excellent headroom, preserving harmonic content, articulation, and dynamic response under extreme distortion.

2N5088 Transistor — Clean Boost Stage

The 2N5088 NPN transistor stage provides a transparent clean boost, ideal for low-output guitars or for pushing the TL072 into additional saturation. Operating linearly, it increases signal level without coloring the tone, adding dynamic response and subtle harmonic enhancement when needed. This stage allows players to tailor output, tighten riffs or emphasize solos
