[Coarse, Fine] Frozen and dysfunctional Hammond M-3 came immediately back to life after one application in the 3 oil cups. That's why I spent $20. 5

Doug	26/06/2024
[Compound] Found the exact product I needed for my vintage Hammond M3 organ. It shipped quickly and the price was great. 5

John	14/05/2024
[Yes] I restored a 68 year old, 1955 Hammond M3 organ in which the tone generator had not been oiled in decades. It is crucial to use the specific Hammond oil and thankfully B&H carries it. After oiling the M3 everyday for four days the tone generator was finally able to start up. It is now working perfectly like a new machine! 5

Albert	07/05/2024
[Coarse, Fine] This got my newly acquired '55 M3 humming again after sitting unused for years. Don't use anything else but this to oil your Hammond. 5

Robert	15/04/2024

[Coarse, Fine] It's the right stuff for the job. Having a 65-year-old instrument with hundreds of moving parts means taking care of it properly. Thanks, B&H! 5
