Hi, I recently got my hands on a Line HX Effects. I have been experimenting with the unit in a 4CM configuration with my various tube amps. I have also paid attention to setting the various signals levels (Intput, Output, Send/Return) to Inst or Line. Moreover, I have kept all the effects to 0db. Despite this, I having a lot of problem getting the overall volume levels of my setup under control. In general, my problem is that the overall volume is TOO loud. In experiencing the following symptoms : 1. Overall sound level of the setup is too loud with the HX Effects. For the same gain/volume setting on my amp, I get a big jump in volume difference when I include the HX effects; 2. In 4CM configuration, if I bypass the FX loop block, effectively bypassing the preamp of my amp (according to my understanding), I get a huge volume increase; 3. When changing effects in my basic linear signal flow, some of the effects create huge volume increases (especially those from the pitch block). My amps are : Mesa Boogie Lonestar special (Buffered Series FX Loop), Mesa Boogie Mark V:35 (Buffered Series FX Loop) and Mesa Boogie Roadster (Series DX Loop). So the Lonestar special has a volumes and one master out. The Roadster has a volumes and one master out. My understanding is the the HX Effects should be unity gain, so I don't understand what is happening. So my questions are : 1. How can I tell if the Send/Return should be INST or LINE level ? If I understand correctly, the Send Level must be INST because it is going into the front of the AMP (4cm). Now, if the the Return is set to INST but my amp sends LINE level, the signal shoud be too loud. 2. How can I tell if the RETURN of the amp requires INT or LINE ? If I understand correctly, the AMP requires INST and I send it LINE, the volume of the amp will be too loud. 3. Many people say that (even with buffered FX loops) the wiring should be lest then 25 feets in order to avoid tone problems. Now, with a 4CM, isn't it almost impossible to avoid such a situation unless you are only using 5 feets wires but that isn't really practical. 4. Can somebody explain why certain effects are louder then others ? Especially those in the pitch block (ex. Octaver and OSC, etc.) ? 5. Can somebody explain the best steps to follow to get all the volumes under control... especially considering that the FX Loop itself has signal level settings. I'm trying to stay with unity gain. Thank you, James

My Spider IV-150 has developed an issue where about 10 seconds into a switched preset, the volume of the preset drops about 25%. This happens with all presets. Initially when this issue began, overdrive presets 10 seconds after selection, would switch to a line-level, clean tone... almost as if no preset were selected at all. After taking it to a tech that used to work for Line 6, he couldn't make it happen in shop (no surprise there). But he suggested doing a firmware update through Line 6 Monkey. I did that and now the presets don't switch to that weird, clean tone. The presets keep the sound but drop in volume about 25% after 10 seconds. I just tried doing another firmware update but Monkey says the amp and MK-III pedal are up to date. Is anyone experiencing this issue? And if so, how did you remedy the problem? Can anyone recommend a good tech that really can trouble shoot and work on Line 6 gear in the LA, Orange County, San Diego County areas? Thanks

Hi Guys, I wrote hoping someone can answer my question. I have a DT25 combo that i bought 2nd hand, I had to replace the stock power tubes and put a pair of JJ. I don't remember how it was before because there was a considerable amount since I played on that amp... Well, Class A mode sound louder (huge difference) than Class A/B (and it supposed that A/B are 25 watts and A 10). Anyone as any idea that what could happened? Class A/B mode sounds loud as I remember class A/B mode, but brighter... and class A/B almost a 1/3 lower than A at the same volume... I think that is not right... but I don't remember which mode sounded louder before... Suggestions? Sorry if I wrote something wrong, English isn´t my primary language. I'm from Chile. Thanks!
