Fire box question

[yotop456]

Hey guys I have a pres Firebox and plan on using a cheap ART Tube MP Preamp
To give my guitars a fuller sound. Has anyone every used this product and think its a good buy? Also would i need to plug this into my line inputs on the firebox instead of the instrument/mic inputs?

I've not had experience with that pre-amp, but it would run to one of the line in jacks on your Firebox.

OK so if i plug my guitar straight in i use the instrument input, but i use my amps headphone/out does that also get plugged in to the line ins?

hm, I'm not sure on that one. you're probably best plugging a headphone out to a line in. I imagine it would be too hot running through one of the pre-amps in the Firebox
