Hohner Marine Band Crossover Bb

After about a year of learning to play blues harp using Hohner Special 20's (mainly C, occasionally A and D) I decided to go for another type of harp in the key of Bb and chose the Marine Band Crossover. After opening the case and taking the harp out one immediately senses that this is a high quality instrument. Well designed and obviously made with great care. The bamboo comb is a unique detail. Unfortunately directions or restriction on cleaning the comb are missing.
The rounded corners of the coverplates are a brilliant improvement over the Special 20's.
The main properties of course are sound responsiveness. Even with my limited experience I think I can say that the Crossover scores extremely well on those.
The harp is pricy but without any doubt worth it.
