Hi there. Love my BE100 (new model, single input with full clean). I don't expect it to be 100% dead quiet at high gain levels, especially in HBE mode. However, last night I was fiddling around with a Dual rec in my exact same setup in the same room and it is WAY quieter than the BE100 no matter which channel i choose. Dual rec CH2 in vintage with gain about noon/12:30, or CH3 in modern with gain about noon. BE100 gain setting is around 7 on the dial.

The noise/hiss/hum is really bad with one guitar (G&L Tribute Cantrell Rampage with SD Distortion pickup), but the dual rec is way quieter with that guitar than the BE100. WAY QUIETER. This is with guitar volume UP but not playing anything. It doesn't happen with my humbucker based strats.

Setup for both is:

Guitar -> Wah -> Fuzz (which is off) -> Amp input
Loop send -> Chorus (off) -> Delay (off) -> Loop return.

I might do a clip. Just curious of others experience here. The BE100 isn't going ANYWHERE.
 
That's odd ... my BE (older model though) is not noisy at all with comparable settings to Marshalls, Mesas and Oranges we use at Rehearsal Factory to jam.
HBE is certainly more noisy then BE but again, not significantly more then other high-gain amps at comparable settings.

May be worth switching some pre-amp tubes around to see if that helps ... if you have extra ones available.
 
Which preamp tubes are for each portion in the BE100? (HBE/BE/loop etc.)
 
Yeah I saw that. it calls out 4 tubes. New one has 5 tubes right (just reading the manual.. I'm not near the amp right now.)

I believe new ones have tube effects loop ... mine has the Metro SS fx loop ... call their shop or email Dave, they are quick to reply.
 
Ok ... it was THE GUITAR.

It is very intermittently causing this noise. Something up in the input jack. Sometimes it will be there sometimes it won't. When it's there it's terrible. Some times it just goes away by moving the guitar around. Dual rec must have got lucky and I played the guitar while the jack was working fine. Who knows. Anyway its NOT the amp.

I may just delete this thread. Stupid me.

No the BE100's have had 4 preamp tubes since around May of 2014.
 
I have an older version of the BE 100 with two inputs, but brought up to current spec with added bass and treble controls for the clean channel on the back.
When I bought the amp from the previous owner, the power transformer hummed very loudly. I sent it to Dave and he replaced it free of charge, and sent it back to me on his dime - outstanding customer service! No hum at all.
However, I still had issues with hiss (white noise) from the amps gain, and switched the existing preamp tubes around. It's a bit quieter now, but since purchasing a koko boost reloaded, I'm able to boost volume and thus, rely less on turning up the master volume which increases white noise. I have the gain on 6, and am able to play in the studio or onstage with little noise.
I must mention also, that I use a Decimator noise reduction pedal (I know some don't like these pedals) and it really keeps things quiet. In the studio, I don't really use the Decimator at all.
At this point, I think I have to agree with other posters, that it's not the amp - but the tubes, guitar shielding, cables, etc. that create noises we may be hearing from the amp. The fact that some amps are dead quiet while others are noisy leads me to believe that we need to check our gear...do some detective work before blaming the amp.
Not trying to create any arguments, just my experience.
By the way, I love the tone of this amp. I urge all of you to try a koko boost out front of this amp if you want even more tonal options and control over your volume.
 
Already determined it was something up with that one guitar. See my previous post. I was doing detective work by comparing it with the dual rec and the same exact guitar, cables, pedals, power source.. everything. The lack of noise through the Rectifier through me off the trail.

Mike D. : Do you keep your Decimator in the loop or in front?
 
I run the Decimator out front. Tried it through the loop but it didn't work as well.
I run everything out front. Have tried different situations with the loop, but ended up
prefering to have all effects out front. I also like having to deal with only the master volumes
of the gain and clean channels rather than reaching around back to adjust that knob as well.
I know Dave has said to set the back knob to around 3:00 and forget it, but the way I set
it up works for my situation. Glad you straightened out your hiss problem. :yes:
 
I have a question for this thread,my appolgies if I am uninformed or late in the game..I have a be100 I got new in 11/15...I have played it quite a bit,I have acquired a hum on the be and hbe channels,I don't recall it being so loud or even remember it being there..I have a low noise floor as far as hiss goes in a high gain amp which is impressive.I use a decibel 11 sw dr, have a h9 in the loop, loop return set to 9 o'clock as recommended any tips would be greatly appreciated,the decibel 11 has the loops which remove all the pedals out of my signal, so Im lost..if its tube time no worries, would that be pre our power tubes to try and loose the hum...thanks again

Make sure no power tubes are red plating! If they are.. you know what to do. if not..
Just try process of elimination..
Unplug everything.. guitar, cord, turn fx loop off.. is the noise still there? If not start figuring out what's causing the hum.. with everything still unplugged turn on fx loop.. noise? if no, plug in your guitar..
Turn loop off, just have guitar, cord, amp. Is the noise still there?
Unplug fx in the loop and switch fx loop on. Is noise still there?
Go through and find if it's a cord, guitar, fx pedal first.
You can even plug your guitar straight into the fx return (turn the return level down first) to see if it sounds ok.

Try all this and update.. It could just be a tube.
 
Will do,thanks..I'm hoping it's a tube,at least that's something I can fix,I can bias and that's about it..I know it's not the guitars,I'm wondering if it is cables close to my voodoo iso5, routed and cable tide..I will plug str8 in,if no hum that's a good sign of relief
 
Well Hilltop,your advice was spot on,kind of silly on my part with,I guess looking for the problem is sometimes right in front of one's feet (pedal board).As you mentioned I went into the front of the be,left the h9 in the loop and hum doesn't exist,as I had remembered..The BE100 is so damn quiet,with the hum gone I could actually hear a tad bit of hiss,unreal how quiet this beast is.With my 5153 red channel I could hear the hiss in the driveway,guess that's not fair to say but it was un-acceptable.Now I have to find some kind of ground loop,shit I want to play guitar,I need all my time to practice not seek out gremlins in my rig.I guess this is the wrong forum for ground hums.Thanks for your help,its greatly appreciated!
