I have been using an original Clarus head from Acoustic Image for many years with great results. My go-to cabinet is a rear-ported Flite enclosure with 1 x 10" Eminence ultralight that was custom-built to my spec. This combo weighs in at around 10 pounds total, making the trip from the car a breeze. In bigger venues, I also play through PA or mic'd. I am now considering either a MarkBass Little Mark 250 or TC Electronic BQ250 to satisfy G.A.S. and desire for a little more "color." I mainly play smallish rooms, 4-6 piece jazz combo on Rob Allen fretless and Pensa J535. Any opinions/experiences with these heads that you can share? Note: I am NOT interested in effects, just warmth, punch, depth, and clean sound. Thank you.
