So my friend I'm teaching needs/wants to buy a bass amp. She's a small person so it needs to not be too heavy. We have checked out a couple of combo amps (Fender Rumble, Ampeg, Mark Bass (12" + tweeter). None of them blew me away, we tried the Rumble 200w ok ish, the 500w (2 x 10") mmm not great, The Ampeg was the low power version, it sounded ok but will need more power (we are waiting to try their higher power combo). Of the ones we tried the Mark Bass was probably the best (http://www.markbass.it/product-detail/cmd-121h/) but apart from it's a bit ugly (and expensive ish) I was underwhelmed. Then my bass rig is MB-1 (with MDRT), Quadverb, power amp (currently Carvin DCM 200L) and 2 x Messa P112s. So I'm leaning toward recommending her spending a decent amount and buying something better than the cheaper stuff. Any ideas guys and gals ?
