most useful app i have for arranging metal

this app is awesome! the quality of the samples and the attention to metal needs for palm muting and tuning are unique to this app.
i use it everyday!

update:
Im currently using arrangements created with Jam Maestro to form a new band. Im using CraigsList with JM arrangements to get attention and the results have been very good. Ive found a bass player, 2 guitarists, and a singer, all because I can create arrangements easily in JM and present them on CL. Im able to weed out a lot of undesirables and also give a good first impression to those who are desirable. Thx David!

FU-thats my name about Jam Maestro: create guitar tab
