I have a bt-350 crate bass head running a 8-ohm black widow 15 cab at 250 watts. I have all the low and mids you could ask for. I want to added a 4-10 cab at 8-ohm to get to a 4-ohm 350 watts rms. will this kill my vol at 175-175 rms ? I need some higher notes to get out of muddy sounds.

actually you'll get everything the amp has to offer @ 4ohms including extra highs!.....im currently running two bag-end cabs w/JBL 15's @300 watts rms!/Gallien-Kreuger Amp.i personally prefer 15's over 12's..

Here's the manual - check pages 6 and 8.
 
You cannot run an 8 ohm cab with a 4 ohm cab on the speaker outputs, because the total load is in parallel, and those two cabs in parallel are less than 3 ohms, whereas the amp needs 4 ohms - anything below that will fry up the amp.
 
The bi-amp option lets you use the BT350 as the power amp for either the high or the low frequencies, and you need a separate power amp for the other part - it's all explained on page 8.

I have a old Fender Music master bass ser# 548565.my dad bought it fairly new. He decided that paint was looking bad and painted over the original paint.Is there any way to take the new paint off?

thank you for your time and answers
