Again thank you for the offer, but no thank you Sir. I'm really not itching to spend any kind of money on something I don't know how to repair in the slightest, even if it's easy for some folks.
Man I tell you I am really tempted to grab this project. Just for fun and at worst have a 2x10 cab to add to my rb115
My first RB112 suffer with high amount of annoying hiss, the current piece are silent except SGT engage with high level.
The tweet on my previous R200/150 are completely no hiss or noise. Believe it or not, the R200c just work like multi function amp , with tweeter engage, sound great on elec guitar, keyboard, acustic guitar and digital drum. Both RB112 and Tech21 200 just sound boxy dry.
Look like there are different type of preamp using on both RB112 and RB210 , but same board dimension.
If anyone is curious, here is the buzzing my RB210 Tweeter made. I am switching the tweeter switch on and off in the clip. Amp volume is set to zero and no bass is plugged in. There is not way this is "normal". I sent it back and bought a Genzler instead.

Yep. Unfortunately all the models I have tried have sounded like this. Doesn't bother me in a band setting but is definitely noticeable in a quiet room.
Can you hear that over a drummer ? For an inexpensive high powered combo it seems fine . Big difference to any Genzler product . Genzler is all pro stuff . Good choice .
no you wouldnt hear it over a drummer. but clear as day when practicing at home.
I get the feeling this would have gone away with use, but I can understand not wanting to wait and see. I’m really interested in this issue.
For me that would be too much amp for home practice. 100 watts max . I like my neighbors . Even my PF50T has them giving me the stink eye . lol
I hadn't thought about this. I might switch it back on, and switch the tweeter back on on my PF-115HE too.
I've not purchased a RB combo, I've been interested and am a long time Ampeg fan, but these kinds of issues with the tweeter give me reason to wait. For small combo needs, I grabbed a Fender Rumble 100 instead a few weeks ago on a Black Friday sale and it's been working like a champ at rehearsal and a private corporate party I just did.
I’ve often had this with new amplifiers, in recent years two of my four Traynors. I also kept them off at first. Later what the heck, turned them on and got used to it, and before I knew it all noise was gone.
Tweeters aren’t only clanking and string noise. There are other tonalities coming out of there. I use a low pass filter (LPF). Even dialing it low, well into the mids below 1K Hz, killing off any high-frequency noise (same with the guitar tone knob) the tweeter remains very musical, yet should put out nothing at those mid-frequencies. Tweeters are an important part of the whole I think.
I am with you on that. I, too, was interested and following this thread but added a Rumble 100 at a great price. Hope this gets sorted out as Ampegs have a great history and tone.
Yeah the combo amp I've been using for the past decade has been a Mesa Walkabout 112, which I still own and love, but after putting so many miles on it I wanted to see what my other options might be. I use Ampeg SVTs all the time, and have a PF-50T that I enjoy as well, so a big Ampeg fan and thus the RB line was an obvious interest. I'm sure if the tweeter issue is a regular issue for them Yamaha/Ampeg will have it sorted out quickly.
