Do you have a budget? The Ibanez Promathean gets excellent reviews on here & also worth looking at are Markbass & Genz Benz combos. You could probably replace the TE 4x10 combo with one, I did.
Had a Trace 4x10 combo & now have the Markbass 2x10 combo which is far superior in every respect (louder, bassier, clearer, lighter & more portable).
