I guess I'm kinda "old school" and out of touch. I have two "boutique" pieces I'm looking to sell to down size my rig. I'm looking to sell these pieces to get two, maybe three pieces and take the leftover money and pay down some credit cards. I'm not in a gigging situation, and these pieces are sitting doing nothing. They are an EBS HD350 head and a Glockenklang Quattro 410 cab. I am thinking of picking up a Hartke 410 XL, maybe a 115XL. And maybe a Peavey Tour 450 head. I play a Lakland 55-02 as my main bass. It has a very powerful B string. Finally the question....Is it "safe" to use the 410 and 115 "full range" ? In the past, I've bi-amped. My Glock handles the B with no problem. What to do?
