Right now i have a Peavey T Max and a Aguilar GS212. I'm thinking of replacing my T-Max with an Aguilar DB750. Does it really make a step forward? I mean can you really hear a $1500 difference? I'm not sure, i also would like to buy a Rickenbacker bass. But I'm a student so i have to make choices. Right now i have a Stingray5 and a Rickenbacker bass sounds much different. When I'm going to record an album with my band, most listeners won't hear I'm using an Aguilar amp, but they will hear difference between a Stingray or a Rickenbacker.. Can anyone give some advice? Thanks in advance.
