I own 2 Mapletree preamps the 2 se and the 4se
They are wonderful preamps that have amazing tone
Dr. Lloyd also provides wonderful service and is a true gentleman, that is honest and practical and will not ever try to rip you off. Value wise his gear is like a honda, even with a 100,000 miles it still gets its price.
If you don't like it, you can sell it here on AC , average sale time is between 5 and 11 minutes.
