I wasn't really sure what to do a search for for this topic so I will post the question and apologize in advance if this turns out to be common. I have returned to the bass in a band after many years of playing guitar in bands. What can I say I love both! To that end I bought myself a 2001 EBMM Stingray which turns out to have a bad preamp. I am thinking of replacing it with a SUB passive setup (which is another thread) For last nights gig I returned to the Peavey Cirrus 4. I use a Hartke TX600 with a pair of HD112 cabs. The Hartkes apparently are known for lo volume so I cranked the OD to just under where it flashes and had the volume set at somewhere around 10:00 and the low end was pretty strong on the E&A strings, however when I played the D&G strings anywhere on the neck really the volume and strength of the tone just disappeared! I have not been using this amp and bass on a regular enough basis to really know why so I hoped someone can shed some light on the lack of dynamics here. I don't know if it is a Hartke TX issue, and active pup issue (god knows it can't be me ) I appreciate the feedback (pardon the pun) Maybe I need a better head and passive bass. BTW we play primarily classic rock from the Beatles through to some 80's. Thanks much!
