Can it be done?
Can a guitar amp be used for bass???
We have some very savvy gear folks in this forum, and I’d love to get their input here on exactly how and why the speakers blow… but for now, I’ll answer this question (that comes up very often) with my own experiences.
First, the basic answer: yes.
Yes, you can use a guitar amp for a bass.
you can hear yourself.
You probably won’t hear enough low frequency
You’ll probably blow the speaker trying to hear enough low frequency
You’ll be under-powered because low frequencies take more power to amplify
My guitar-amp experiences?
When I started, I had an 8" guitar amp as my practice amp. It was also my only amp. I played in a punk/metal band with my friends, and within a year, the speaker was demolished. I had it cranked all the way up all the time, and it was just a poor little practice amp.
It worked great as a practice amp in my room, but didn’t work at all in a context with moderately loud guitar… and let’s not even mention the drummer.
I bought a Bassman 50 - 50 watts of tube power for, as the name claimed, a bass player. Alas. The bassman is not enough power for bass. It’s great for a practice room, or an exceedingly tasteful acoustic group… but with keys and guitar and… let’s not even mention drums, please.
Unless you’re this guy and you’ve got the thunder of the rock gods on your side, I’d recommend against a guitar amp for bass.
