I've been looking for and needing a boost like this for years. Dirty or clean patches this pedal nails it and gives that push up the hill when i need it! I'm very happy overall! Great job Mason and company! Thanks for everything.

Thank you for the very nice Vertex boost.It is doing good things With my lovely Guytron F/V 100.Its like lifting a curtain on the clean,and pushing without killing the tone on the overdrive channel.Very flexible with the volum option! Just ordered another one and a Steel String!! Thanks again
