The legendary roar of classic British rock amps holds a special allure for guitarists. Gosh Amplification understands this passion, and their Problem Solver 50-Watt all-tube head is a testament to both respecting tradition and pushing boundaries.

Gosh Problem Solver Backstory

The Problem Solver’s story began in 2016 on the porch of Chris Wollard’s home. Fueled by a deep love for the 2204 circuit, Wollard and a collaborator embarked on a quest to both honor the iconic design and solve its inherent limitations.

Years of meticulous refinements and countless prototypes led to the Problem Solver – a true homage to the past and a powerful tool for today’s guitarists.

It covers a lot of ground and does that Marshall thing very well. Think Classic Rock, through to higher gain ’80s tones, and you’ll be in the right ballpark with this head. Then factor in all the added extra updates and refinements, making this amp one that you need to check out.
