Hard-riffin', quick-picking Zach Wish gets comfortable and loud with the 50W solution to chasing the different gassed-up eras from the beacon of British rock.
Gosh Problem Solver backstory: The journey began on the front porch of Chris Wollard’s house, back in 2016. Fueled by a shared passion for the 2204 circuit, Wollard and I embarked on collaborative process to redefine the circuit, ironing out its quirks and limitations. The result is an amplifier that not only pays homage to its roots but catapults the classic rock sound into the modern era.
The relentless pursuit of sonic perfection led to numerous modifications and revisions, transforming the 2204 circuit into a beast of its own. No longer bound by the constraints of the original design, the Problem Solver emerged as a versatile powerhouse, ready to unleash its magic in both studio recordings and live performances.
What sets the Problem Solver apart is its thoughtful array of features, carefully curated to empower your creativity. The AGE switch lets you tailor your tone stack to different eras – whether you crave the cutting-edge brilliance of 1963, the aggressive bite of 1966, the mid-heavy roar of 1981, or the warmth of 2023, it's all at your fingertips.
The Mid Boost switch elevates your highs and mids, ensuring your solos cut through the mix with unparalleled clarity. The Depth control allows you sculpt the low-end frequencies. And the revamped EQ controls provide a logical, intuitive layout, ensuring that you can sculpt your sound effortlessly, straight out of the box.
In the end, the Problem Solver Amplifier isn't just an homage to the past—it's a celebration of timeless tone, reimagined for the demands of today's musicians. Join us on this journey and discover a new era of sonic possibilities. Plug in, play, and let the music do the talking – the Problem Solver has arrived.

Revv G3 Purple Channel Preamp/Overdrive/Distortion Pedal - Anniversary Edition
The Revv G3 revolutionized high gain pedals in 2018 with its tube-like response & tight, clear high gain tones. Suddenly the same boutique tones used by metal artists & producers worldwide were available to anyone in a compact pedal. Now the G3 returns with a new V2 circuit revision that raises the bar again.
If 3 Were 6
With six times the controls found on the 1 and 2 versions (if you discount the original’s on/off slider switch,) the LPB-3’s control complement offers pre-gain, boost, mid freq, bass, treble, and mid knobs, with a center detent on the latter three so you can find the midpoint easily. A mini-toggle labeled “max” selects between 20 dB and 33 dB of maximum gain, and another labeled “Q” flips the resonance of the mid EQ between high and low. Obviously, this represents a significant expansion of the LPB’s capabilities.
More than just a booster with a passive tone, the LPB-3 boasts a genuine active EQ stage plus parametric midrange section, comprising the two knobs with shaded legends, mid freq and mid level. The gain stages have also been reimagined to include a pre-gain stage before the EQ, which enables up to 20 dB of input gain. The boost stage that follows the EQ is essentially a level control with gain to allow for up to 33 dB of gain through the LPB-3 when the “max” mini toggle is set to 33dB
A slider switch accessible inside the pedal selects between buffered or true bypass for the hard-latch footswitch. An AC adapter is included, which supplies 200mA of DC at 9.6 volts to the center-negative power input, and EHX specifies that nothing supplying less than 120mA or more than 12 volts should be used. There’s no space for an internal battery.
Power-Boosted
The LPB-3 reveals boatloads of range that betters many linear boosts on the market. There’s lots of tone-shaping power here. Uncolored boost is available when you want it, and the preamp gain knob colors and fattens your signal as you crank it up—even before you tap into the massive flexibility in the EQ stage.
“The preamp gain knob colors and fattens your signal as you crank it up—even before you tap into the massive flexibility in the EQ stage.”
I found the two mid controls work best when used judiciously, and my guitars and amps preferred subtle changes pretty close to the midpoint on each. However, there are still tremendous variations in your mid boost (or scoop, for that matter) within just 15 or 20 percent range in either direction from the center detent. Pushing the boost and pre-gain too far, particularly with the 33 dB setting engaged, can lead to some harsh sounds, but they are easy to avoid and might even be desirable for some users that like to work at more creative extremes.
The Verdict
The new LPB-3 has much, much more range than its predecessors, providing flexible preamp, boost, and overdrive sounds that can be reshaped in significant ways via the powerful EQ. It gives precise tone-tuning flexibility to sticklers that like to match a guitar and amp to a song in a very precise way, but also opens up more radical paths for experimentalists. That it does all this at a $129 price is beyond reasonable.
