My choices are a Aguilar db750 or a Thunderfunk 550. I think one of these should fill my needs and that is to get a more old school classic rock/metal sound. What I own is quite different from what I am looking for. I have a euphonics audio iAMP combo 350. Since I joined this new band, I needed more volume and bottom end so I bought an Aguilar 115 but it is not a good pairing with the EA. Between the 10 in the combo and the boomy 15 from the aggie there seems to be a real gap. I tried the 115 on it's own and although it can boom on the low end it lacked some of the higher definition I am used to with the EA. So I have a dilemma, do I just set aside the EA and get a new head and then another cabinet to bring out the mids? Or should I build on the EA with a different cabinet hoping that 350 watts is enough? Experience would be greatly appreciated.
