So I purchased a new bass just the other day. I got a Warwick Corvette 4 string. Since picking it up, my roommate has been working the overnight shift. Because of this I've been playing it mostly through my headphones, which are connected through the head. So my problem is this: The bass sounds absolutely amazing through the headphones. It really has that unmistakable Warwick sound (the growl and punch of the lows and the cutting clarity of the highs). Conversely, when I play it through the head and cab (no headphones) it sounds good but it does not have the same sound. There is a noticeable difference. I just can't seem to adjust the settings on my head to replicate the tone I get with the headphones. Like I said, the bass is a Warwick Corvette, the head is a TC Electronics BH 250 and the cabinet is a Peavey 115. The TC head only has knobs controlling the volume (obviously), bass, mids, and treble.... Has anyone else had this problem before?? I've only been playing for a short while and this is my 1st real upgraded bass since I began playing on my cheap Ibanez so I have yet to encounter something like this. Please advise!!!! Any and all help would be appreciated. Thx in advance!!!
