which ashdowns do you have and do they run good with effects. also are the tone controls hard to handle or are they pretty easy to get a good tone out of? more specifically the swr sm-900, and how is it with effects? and are the tone controls good to handle or no? i ask because i have the oppurtunity to get an abm 900 evo II or an swr sm-900 im trying to figure out which i want. i need to know by tonight though. thanks for all your help.
