I am using a Hammond 44 Hyper on this solo. at times it sounds more like a soprano sax than a melodica. For the intro (verse) it is a combination of many melodicas including bass. (see credits at end for the melodicas used) This group of melodicas work well together. I will be uploading another Monsters of Melodica Video soon where the original Hammond 44 Melodica is featured in the solo. The sound is completely different. The use of different melodicas is necessary depending on the type of music or even the song it self. I have found that combining melodicas can really make the sound full.
