Hey there!
I'm not sure if I should post this on here or over at Diezel's but since the "problem" occurs only if I plug my Diezel into the VB-101, I will start here.
I've been using my trusty VB-101 to mainly record my Diezel VH4 since 2011 and it's been working fine, as far as I can tell. I haven't been able to record for some time because I had to relocate my recording space. What I've been noticing for a while since I've been recording again is that the low end seems to be (or have become?) extremely loose up to a point where I had to dial the bass way back on the amp's channel to keep it tight. What concerns me even more is that the problem occurs even stronger the further I dial down the deep control. Yes: less deep -> more flabby bass. And when I come close to "0" on the deep, an unpleasant lower harmonic is added to the signal and AT "0" a constant buzz is created the moment I hit a string. This buzz is also present in the chassis of the amp itself. Also, it seems like whatever I play comes out of the chassis! (WTF??) This entire effect is amplified the more I turn the presence down. If I have both deep and presence at "10", the sound seems to be ok. I keep the master volume at around 9 o'clock, so relatively low. Channel volume is at around 11 o'clock.
Here's the thing and the reason why I post this here: The amp doesn't do any of this while plugged into a regular cab. It sounds perfectly fine on all settings, I twisted every knob to every position.
So does anyone have a clue as to what could be happening here? Could this be a bias issue? I've had the power stage retubed last year, the tech measured everything then and said the amp was a beast and working fine! But that was before I was able to hook it up to the VB-101 again.
Thanks a lot for the help! Greetings,
Till
