I have three choices and not sure which to do. I have been offered a Markbass 2x10 combo for £620 to go with the Markbass 2x10 cab I already own. Or, I can sell the Markbass 2x10 cab for £300, and buy an almost new GK MB210 combo with the matching 1x15 for £520. Or, I could buy a new GK MB212 combo for £600. Financially, I guess the used GK deal is a no brainer, but I'm still not sure what to go for. The Markbass combo has the tiltback feature which is great, but I could get a stand for either of the GK combos to raise it and tilt it back, and if I discovered I didn't need the 1x15 I could sell that off and make a few quid back. I'll be playing a Fender MIA Standard Precision through this so let me know what would sound best tone-wise. Thoughts?
