I play guitar primarily these days, although have (briefly) played bass in a gigging band. Last time I did that I had a Hartke 3500 2x10" Combo -- it was awesome but a big, heavy box to move around (I know there are larger ones, but that's not the point here). Since then, a friend GAVE me a Markbass Mini CMD 121P (Linked to Info). It's an AMAZING piece of gear for its size. But -- there's something wrong with it, I think related to heat. It's great for basement jams but get it outside on a hot day and it's.. UNRELIABLE. Just shuts down. SO -- There may be something coming up late this summer where I'll need a gig-worthy bass rig (assuming the disease cooperates) and I'm looking to utilize the Markbass Speaker/cab. Options: 1) Buy a used Markbass head that'll slide right into the spot where the old head unit was. 2) Buy a small/Class D amp like one of these and use with the MB cab: - (New) http://www.markbass.it/product-detail/nano-mark-300/ - (New) https://www.tcelectronic.com/product.html?modelCode=P0BRP - (New) https://www.tcelectronic.com/product.html?modelCode=P0CQS - I'm sure there's an Ampeg, etc. 3) Other suggestions..? I would love to keep spending to $300, and I have no issue buying used gear. Any and all suggestions welcome. THANKS..!
