Each speaker works independently from each other. One speaker may use more low frequency tones than the other one.. Low frequency tones create a lot more noticeable vibration than higher frequency tones. You can reduce it by turning the volume down a little on the left speaker. It is possible that nuts came loose on the speaker.
Why listen to directions (and MP3s and phone calls) on the speaker tinny little in your<b> GPS</b>? Many high-end <b>GPS</b> receivers are equipped with an FM transmitter to send audio to speakers car stereo. This may work in rural areas where the FM band is not as crowded, but to find a free frequency, will be a challenge in cities.<br />
One possibility is to use the headphone / audio jack, you can also find an average level of <b>GPS </b>units. Connect the cable car stereo aux patch, and the bliss of static-free sound.<br />
The frequency of mid range control is about 1KHz. The bass and treble are usually enough to set the tone of sounds and music, and if the customer has high quality speakers connected to the amplifier it is almost unnecessary to modify any tone. In my opinion you are right that x-band equalizer became less important now. Thank you. gylacz
When you are changing the DSP effect on the fly, static or noise is NORMAL !!! The DSP is changing the data and having to recalculate on the fly and doesn't mute itself while doing so which results in "garbage sounds out".
The bypass setting should NOT get any tone UNLESS you have feedback going on. If your guitar can "hear" the speakers in the amp, the strings can vibrate and get feedback going.
Unplug the guitar and see if high freq tone is still there on bypass. If the tone is in the musical range, then there is a problem if nothing is plugged in. If it is a VERY weak, very high frequency tone, this may be the digitizing noise from the DSP. On bypass, the audio is likely to still go through the DSP, just not be modified by it.
Hey ajn1n1 we need to fine where the tinnyness is coming from Lets do a test shall we,
hook up your voice matched polks to your front left and right speaker outputs on your amp to see how they sound as mains. if you hear tinny then its the speakers. sometimes speaker need to be broken in a bit.
hook up your main front left and right speakers to your rear outputs. if you hear the tinnyness then its the output of that channel on the amp or a setting. Newer amps let you change speaker sizes in the menu so that it can change over the crossover for that channel.
Both of your problem amps were made in the '70's or earlier. It is entirely possible that the coupling capacitors are failing. This is an issue for a service center whether it is caps or something else, like failing tubes.
The good news is that installing metalized polypropelene capacitors will make those classic amps sound incredible.
