The other day just out of interest i borrowed my friends pedal that allows for two amps to be ran at the same time... I hooked up my marshall amp and my old bass amp (200 watts solid state) with another 4X12 cab and a 1X18 cab. The sound i got from that was surprising... I put a boss overdrive pedal in the signal path so it effected both amps... the marshall was the overdrivven distortion sound im used to, but then the bass amp running at the same time, created a gritty low end sound. I really liked the sound it made, good and dirty for the style of band i play in. What i NEED to know before i do this again, is if its safe. Am i going to damage anything by using a bass amp with an electric guitar? Or is it safe to use a bass amp with an electric guitar?

Thanks to anyone who can answer this question for me.

Id also suggest if you are going to mic a guitar cab a good method i came across is to use 2 SM57s not betas just the regular type point one directly at the speaker and EQ it with NO bottom end then take another and angle it in from the side so you get this sort of positioning | \ then EQ the angled mic with no top end. Then mix the two together. This way you get a balanced sound which is big enough to be used in mono as a rhythm part rather than having to do endless takes of the rhythm track and then panning them all which ways. This all saves tracks which in home studio cases really helps.
