I am in the process of buying a new bass amp. My behringer1200 crapped out on me last week during band practice. so now i have practice again tonite and i have no amp! i have a 15 watt guitar amp. if i plugged my bass into that and kept the vol on the amp low and miked it to the pa which i can crank will that work? i dont want to ruin the amp but if its at a low vol it shouldnt hurt the speaker too much right? what about feedback issues with the mic in front of the guitar amp? i'll bring me earplugs! will i get a bassy sound at all? i know it will sound not so great but as long as its tolerable it will do temporarily. we play at a rehearsal studio and they have a pa and mics you can use for free but to rent an amp cost $10 an hour. I dont think they even have bass amps to rent. i am broke otherwise i'd just lay out the 10$ for the two hours we play. any suggestions or thoughts?
