Alright! I'm switching from a SVT 4Pro set up to an preamp pedal/amp rig for both cost and versatility. The two main cabinets that I use are an Ampeg SVT 810 and an Ampeg PR-410. Please keep it to the short list or something that fits the bill. Needs: - Be able to drive an amp - DI out - Good tone stack! Wants: In order. - Selectable gain stage or second channel. - Tuner out. - Tube - Gate and/or compression I'd like to keep it in the $300 and under range. If I go above that then I might as well get the Meatsmoke I will want eventually. Short list: Aguilar ToneHammer Darkglass B7K Eden WTDI Tech 21 VT Bass Deluxe Sadowski Preamp (I'd likely just build a clone to try) Any feedback or other suggestions? (please keep it to applicable qualifications and price range). Also, I have an MXR M80. I like it but it goes somewhere else in my arsenal and I don't want another.
