Hi there.Read lot of good stuffs about Puma 500 and 900,especially like that they are transparent,loud,good sounding heads and do not color or do it in very subtle form your sound when they be pushed hard ( or am i wrong ? ),so i would like to have one - it would match my J bass with Delano JMVC5FE set and Noll electronic.Very like this taste knob . I am happy with how sounds my bass now and i would like to have it same tone at high volume without any or less colorations and distortion from the cab but there is my missing link - need a good one.Need one which would sounds very balanced and neutral at high volume -i would play fusion,funk,pop etc. stuffs.Boiled down to few cabs but i will appreciate any other thoughts and suggestions then mine,so here they are: 1.TecAmp S212 or M212. 2.Bergantino CN212. 3.Glockenglang Double. 4.Accugroove El Wappo Jr. 5.Barefaced Super Twin. Bear in mind that i would not be able to test any of them,which is bad thing i know but none of them have dealers in BG. Thank you for your time.
