I own an Ibanez RGD2127Z with stock pups... I know, I will be changing them to DiMarzio D-activators soon as I need as much definition and tightness as I can get. I recently bought an ENGL Fireball 100 head and coupled with my uber-shitty Bugera 212V-BK cab, I can't seem to get nice, tight riffage on the low E and low B, crazy as that may seem with an ENGL... I'm already taking care of the pickups as the V7-7 and V8-7 stock pups are great, but very loose and muddy on the low E and low B strings. I'm dead set on either a set of D-activators or a D-activator bridge and liquifire neck pup. The main piece of advice I need from as many of you who have experience in this regard is: I am keeping the Bugera cab as I feel it's just fine as a wooden box (nice, sturdy wood with a closed back), but hate, hate, HATE the stock speakers. They are loose in the low end and flubby when palm-muting, especially the low B.... Extreme tightness and definition with palm-muting as well as extreme clarity and punch for lead work are the most important things here, please recommend me a good set of speakers. Thanks in advance!
