Brought in my 2 channel Mesa Dual Rectifier that two other shops couldn't fix. Circuit Surgeon had it sorted within a week. Sounds better than ever.
Really fair pricing and clear communication throughout. I got a full breakdown of what was wrong before they did any repair work. Def recommended.
My Roland keyboard desperately needed some love. Circuit Surgeon sourced the discontinued parts and even replaced the worn felts after 20 years of playing — it's like a brand new instrument.
Everything you need to know before sending in your gear.
