I was quite pleased to have won an eBay auction for a Roland Micro Cube having missed out on a few; it was a fair price, despite not having the power adapter (if they come with them then why are so many advertised without??).
Anyway, sourcing the 9V lead is proving a task; official ones are around £26 new (which is steep compared to the amp's cost - good luck finding a used one), and the reviews on eBay/Amazon for non-Roland replacements are almost universally bad, stating that they can wreck the amp and hum.
Surely there must be an excellent option at a reasonable price? Suggestions please.
