    What is the general effect of the speaker grill cloth on the amps sound?

    I have an amp with a large meshed grill ( I assume it represents almost no barrier to the sound waves in this form) and want to cover it with another for a more traditional look. I'm afraid people would expect me to play blazing metal licks when they see it on stage.:lol:

    Grille cloth tends to reduce high frequencies slightly. In high end home audio you might notice but with a guitar amplifier I would have serious doubts if anyone would deem it a significant change.

    Some of the thicker grill cloths absolutely cut highs a noticeable amount. That's one of the variations among Marshall 4x12 cabinets. What you have now won't cut highs at all.

    Thanx, I thought it looked more like a metal head piece of gear. Second channel is too high gain for me and reverb is not so good, but channel 1 is clean, almost fenderish and pretty much ok with some pedals. Got it cheap after my Peavey Classic 30 died. It has Celestion 70/80 which got better after a few months of use. Or maybe I just got used to it. It was a big change for me at first, after the Classic 30.

    Theoretically,it changes the sound slightly, but I've never heard a noticeable difference with a guitar amp. I like that Randall!

    It's very minimal unless you are not using grill cloth and using cloth for clothes or drapes!

    Do the math... those diamond-shaped holes take up way more area than the grill itself. The edges of the individual holes in the grill will scatter (not absorb) high frequencies, but the much larger holes let through way more highs un-affected.
    I seem to remember Mesa claimed their jute grill cloth helped to cut some edge off the high end.

    Most guitar speakers won't reproduce much above 5 KHz. Any slight loss of high end can be compensated for with a tiny turn of the amp's treble control.

    I did quiet a bit of research on grill cloth years ago one article said pretty much any nylon single stitch material would be fine. I would hit a large fabric store and find stuff on the bargain tables in my own test covering the amp with the cloth I noticed no deference. The article also said material like cotton was a bad choice. Also eBay is a great source for finding SPK cloth. I think it's one of those subjective subjects.

    A Dollar Store place mat as a grill cloth. It is a mesh, I used some dye to make it look about the age of the cabinet. P-P 12AQ5's and a 8" speaker.
