TC Electronic BG250 Club (Part 2)

I have disconnected the tweeter completely (bg250-115) and as far as I remember there was not any audiable difference.

Cool I'll try put all scenarios tonight and post my findings tonight. Cheers bro

Right so the noise is a high pitched frequency which occurs from the tweeter only when the bass is plugged in with the treble on the amp and or the treble on the bass is turned up. The cables are new fender cables, no pedal and on 5 different basses. Its definitely the tweeter making the noise. Should i replace it?

Just disconnected it. As you will find out its not that great quality anyway, so probably that will be a good thing to do. I still have a high frequency hum when all treble knobs are cranked but this is not my playing style anyway and apart from this I think all amplifiers with these settings will make an audiable noise up to some extent. Also I don't think it is noticeable in gig volume.

I might just disconnect it. That had crossed my mind. I had noticed it since i first bought the amp and it never caused issues gigging as i play ska/reggae and my treble is always rolled off. But i was getting lost in the mix on stage so i turned the treble up and found the hum was being picked up by the desk. I wouldnt mind replacing it and see how that goes. Just dont know what brand for tweeters would be good to try or what wattage the original tweeter is so i dont blow the new one

There is also a capacitor/resistance (something like that) that you might want to replace, maybe these parts introduce hum. They are soldered straight on the tweeter terminals so you won't have to disassemble anything else. But the most important of all, keep in mind that I am not an electronics engineer and maybe all I say is wrong.

Its all good man either way your opinions appreciated. I decided to get my mate around. He males his own pedals and amps from scratch so im interested to see what he says. On the phone he pretty much said peizos aren't great and prone to making noise. He was talking about dropping the 15" speaker down and adding a 5" speaker for the highs. Ill keep yis posted

I joined the club. Just bought two BG250 208 with the intent of using the head from one and using the other as an extension cabinet/backup amp. So far I love it, but haven't played the two together yet, forgot to get a speakon cable, my old rig used 1/4".​

I've almost pulled the trigger on a second 208 to do just this several times now because the used prices have dropped to the floor. I'm curious how you like it once you get your speakon cable.

Looking at getting the bg250-208. Can someone help me understand hooking up and external cabinet?

How many watts and ohms should the external one be? What is the deal with the cables? I see some warning in the instruction manual but I don't understand what it means.

I was looking at adding an Ededn ex112 to it. It's available in 4 or 8 ohms. It's 300 watts. I'm worried if the total power of the bg250 is 250 watts and the Eden is 300 watts, that after powering the 2 8's in the combo itself, there wouldn't be enough leftover power to run the Eden, but I may be way off base. Can anyone help me out?

Use a SpeakOn cable. Any regular 8 Ohm bass cabinet will work.

Yes, there is enough power to run the extra speaker - regardless of size, as long as its an 8 Ohm cabinet. That amp is safe down to 4 Ohms. The two built-in speakers combined look like an 8 ohm cabinet to the amplifier. So you can add one more 8 Ohm cab through the SpeakOn jack on the back.

The Eden 12 will beef up the sound and be a bit louder. Because it's quite a bit more efficient than the two eights in the combo. You should have a nice, round sound.

Sweet. I appreciate your quick response, as that Eden is actually available to me for insanely cheap right now and I wanna jump on it quick if it's gonna work.

Just to add to what Frankie said, the internal speakers are only going to get about half the max power with or without the extension cabinet, since they show an 8 ohm load to the amp. With the 8 ohm extension cabinet, the amp will put out it's full power, half to the internal speakers (125W, or 62W per each 8" driver) and half to the extension cabinet.

I have the Eden EX112, and it's a very, very good speaker for it's price range. It's very efficient and should add a lot of volume. That said, I don't think it can actually handle 300W. I would not try to push nearly that much power through it

Note to Group:

I read that the Digitech FS3X pedal works great as a footswitch for the Toneprint enabled amps. I found it on Amazon for €22 so I bought it and can confirm that it works great. I think I saved almost €50 with this tip, as they wat €69 for the TC dedicated footswitch.

Similar but different, you have any idea if a single footswitch (like this one Strymon Tap Favorite Footswitch Pedal | Gilligan's Gear Sales) would work to mute/unmute the single toneprint effect on the bh250? I don't have any interest in switching between two banked toneprints so I would have no use for the digitech that you mentioned. Thanks!

Last night I powered on my BG250 115 but there was no sound coming out at all although power led is on. Dead quiet. I tried with another cord and bass but still the same so it must be amp. Tuner doesn't show any activity so I guess it's the preamp? Anyone with the same problem?
 
#1,416
Problem found and fixed. Somewhere a bad solder.

good work running that down - :thumbsup:

It didn't make any sense the way it stopped working, I hadn't push the amp hard or anything. I had to double check the input jack, first check was with the knobs PCB stripe mounted on the chassis and I failed to notice the problem. That was when I posted in here. Then I though I better remove the PCB and check those through hole pins because PSU and amp sections looked clean.

I just bought my second BG250-112 combo. I purchased my first one 4 years ago. I've been gigging with it extensively and blasting through it pretty loudly at times --it hasn't hiccuped once. I saw that they aren't being sold new anymore; just in the used market, so I picked up another one just to be safe. I use it for showroom gigs, casuals, etc.. and it's been loud enough for all of them. I play electric bass and upright bass, and it works equally for both. I like it because it doesn't have a baked in tone. It's pretty natural sounding, and puts the low end out into the room better than most combos. For me to buy another just for backup says a lot.

I totally agree - great sounding lightweight small/medium gig amp! :thumbsup:
