As an amateur poor room guitarist, I'm always searching for some ideas about how to get a nice guitar sound without having such big, expensive amps, cabinets, and other sound equipments. So, I'm ended up here like some (or many) of you. I see some electronic and software solutions out there to eliminate high frequencies and get much responsive sound like famous cabinets.
Software speaker simulators, as far as I know, is the best option for recording. They really sound detailed. But, some guys don't like the sound of digital processing or it's not practical and use electronic simulators which are not so detailed like software one and they mostly and simply behave as a low pass filter. Of course, Palmer simulators and other such expensive products are out of our subject.
As you know, the speaker cabinets can be configured to get some filter behaviors. They can boost or eliminate certain frequencies. Also, the speakers which produced special for guitar sound are naturally mechanical filters and have more characteristic response unlike hi-fi speakers.
The goal which I'm trying to reach is a cabinet simulator that is simple, inexpensive, organic (i mean not digital) and really sounds like a speaker. Using an electronic simulator through a small amplifier and a speaker then miking it up to get speaker dynamics is the simplest solution. But, I'm on something else .
Obviously , the main problem of the small speakers is high frequency part. So, most of the solutions are aiming that for now.
The first thing I experienced is a 5 cm. speaker attached directly to a 15cm. PVC pipe. This construction boosts low frequencies as you can see in a regular sub woofer design. But there is no box behind of the speaker. To eliminate high frequencies, I used some sponge in front of the speaker . A Samson Q8 microphone was used to capture its sound and applied some post filters. The mike was in the pipe, that is the most important part of this experiment. And the drive sound belongs to POD 2.0. Much sponge might have helped to eliminate the fizzy sound or some notch filters could do the trick. Actually, the original record by Inflames has some fizz in it too
Here the sound sample:
Let me tell you something just here, If I use the same settings on POD with POD's own cabinet simulator I don't get that distorted sound. It's much clear sound. You need speaker distortion for the best way to get a good guitar sound, it's not important if the speaker is small or not.
After that I tried two 16 cm. car speakers attached to a wooden cabinet. The cabinet has a hole on the left side and I miked up the cabinet through that hole. Boss GE-7 and a modified Digitech Death Metal pedal were used. Microphone was a cheap computer microphone . This sounds huge in my opinion.
Ok, second option is not good enough for recording at night, its a bit loud. But the first one is completely silent and I recorded the sample at 2 am.
By the way, I want to share some other tricks which I noted. Using wool in a cabinet reduces the "box" sound and make it dark. This is a good trick for small cabinets. Also Whatever you use in front of the speakers changes the characteristics of the sound. For example, they use clothes to protect the speakers and for a good appearance. In fact, it effects the clarity of the sound. And I want to test isobaric construction sometime. This is another trick to eliminate high frequencies.
In the second part I will introduce you a final design. It will be a recording box with mechanical filters, just ready to plug and play. It's not done physically, I just want to share what is in my mind and discuss to improve it.
Thanks for reading, sorry for my crappy English and guitar play , please share your thoughts.
