Hey everyone Im on the market for a preamp.I use Rickenbacker 4003 .I want the preamp to reveal growly aggressive mids of a rick. What are your suggestions ? I am in between of tech 21 vt bass di ,TWO NOTES LE BASS,Hartke Bass attack and GK Gallien Krueger PLEX . Im not satisfied with GEB-7. Im thinking of selling it and getting a Source Audio EQ2. What are your thoughts on that ?
