Testimonials

Geoff fixed my Hammond Organ. He is amazing. He’s my best friend. He comes to my house. We eat food together. I play songs for him and write the charts too. He is the best.

Peter Geohegan

My Hammond was completely fucked, but Geoff went ahead anyway and made it great again. Then I bought a new one. And then another one. I don’t know how many I’ve got now.

Liam Kealy

I had this Leslie Speaker and Geoff made it sound really loud. You’ll never guess how loud it is. You should come to the Rainbow Hotel one Monday night and hear how loud it is.

Tim Neal

I never used Geoff, but I like his style. He’s a warm cat with the personality of a tuna fish. Going one way, but heading in another at the same time.
