I am about to purchase a Crate/Ampeg V1512 Combo and a ceramic tone tubby hemp cone speaker is offered as an upgrade. How much will this improve the tone of the amp particularly in warming up the clean tone? I have been offered the amp at such a discounted price (old friends with the dealer) that it is cheaper with the upgrade than it would have been without it normally. I know nothing about speakers but these seem to have a pretty large fan base.

thanks for any help,
Eli

ive only used the alnico tone tubbys but i really liked them. i have a cannabis rex thats a ceramic hemp cone speaker but i havent really done much with it, but from the initial sounds it is a good sounding speaker, but i think it takes a while for the hemp to break soon
