So I'm fairly new to bass. Former guitar player. I got my first amp ashdown mag300r a few months ago. I have no complaints about it. But I put out an ad to see if anyone wants to trade. How will I ever know what I like unless I try it out right? I was hoping to trade for a gk mb200 but thats kinda a long shot I know. Anyways, a guy responded offering a sansamp rpm preamp and an american audio vlp300 poweramp. Is this a fair deal? I know price wise its pretty even I think. But are there any cons/pros to going with a separate preamp/poweramp rig? and tone wise? BTW the way I use the mag300, I dont even use the eq section. I bypass all eq controls and switches. So its basically the raw jazz bass tone. opinions?
