Sorry dude, the G-Force is a pain in the behind to use witht he VH4. Reason being is that when you have mechanical switching (dizel uses true bypass relays) to completely switch out an effect. The switching suffers from DC imbalances. In a normal effect, if you measured the amount of DC...

I remember there being an example settings chart when I first got my VH4... Does anyone know where that is now? Cheers, John

Thanks peter... At least its not an amp issue... Would you suggest I put a 1M resistor to ground on the input and output of my pedals? Is it normal for the VH4 to pop when the channel insert button is pressed when there are no inserts plugged in? also, if I have a pedal in an insert but...

Hey guys I was wondering if you could help me... I've recently started using an eq in the channel insert of channel 3. This is the first time I've ever used the channel inserts... I've noticed that I get a loud popping sound when doing certain things. NOTHING IN ANY OF THE LOOPS: The amp is...

can I ask what power tubes you have in your VH4 when you recorded this clip? Cheers, John

So ideally I should bias them, then play around for an hour or two to let them break in, then rebias to perfect it? What sorts of changes in sound will I expect to hear when adjusting the bias higher or lower? Svetlanas eh? :cool: I was looking at the watford valves harmas as they seem to be...

Thanks for that, pretty straightforward stuff... Out of curiosity you mentioned 6L6: 60 to 70 mA Whats the benefits/drawbacks of setting this to 60 or higher to 70? Would you reccomend a sweet spot? Seeing as I'm biasing a pair at a time, do I just need to buy 2 matched pairs or should I buy...

hey guys, I want to try and install 6L6CG tubes in my VH4 an would like some information. Is there a VH4 biasing guide like the herbert one on the Diezel website? I don't really want to buy a biasrite and would rather do it with my multimeter, I'm tchnically minded and build PCs and guitar...

went to the store and bought a bunch of 3,15 amp slow blows. everything is working fine now but I have a question. in the manual it says that in the us (110V) you should use an 8A fuse for 220V operation you should use a 4A fuse... I'm in the UK that ranges from 220-240 and on my furman...

Hey John... It's weird becuase this is happening 'with' my furman. Really strange... I'll buy some fuses when I can get to the store. Thanks for the help. John

Hi Peter... Is this a different fuse than normal or just one of the usual ones? Is there a reason for what happened or am I just unlucky? :) Thanks, John

Hey, A while back the main fuse blew on my VH4 as soon as i turned ont he amp. I replaced the main fuse and it worked perfectly after that and now a month later it's just done it again. I don't have a spare fuse so I'll have to get some however does this mean my power tubes are bad? Even...

Hi John... No I haven't tried it in the parrallel loop as I've always wanted it in the serial loop to get the most out of it... I'll try it though and set it to 100% wet and see if the noise still appears... Thanks, John

Hey guys... Nearly got my rig sorted now, however I have just one more obsticle to get over... My VH4 is really quiet now... only a tiny amount of hiss and hum in its base form (and thats when listening closely). Only problem is that when I add a G-Force to the serial loop, even on unity...

hey bleedback, It's a small trimpot (the kind you adjust with a screwdriver, not a knob) inside the VH4 that allows you to fine tune the amount of hum coming from the amp. I ajusted it and still get a slight hum, so I adjusted it to a happy medium where its hardly noticable unless miked up and...

found it... thanks...

Hey guys, was wondering where the hum trimmer on the VH4 is as I'm getting hum after changing my preamp tubes? Does it change the sound of your amp if you tweak it too much? Thanks John

Hi Peter, I'm currently re-tubing my amp and was wondering if you could tell me the correct order for which tube affects which channel etc... I've searched on here and it seems that there are 2 versions and I was wondering which was the correct one? Thanks John

Thanks John, Yesterday i went and ordered 3 Tung Sols... I intend to try them in V1, V4 and the PI. I want to see if I can tame the noise that was getting previously... Once my amp is stable again, do you suggest I switch to Rubys? This is the first time I've bothered with tubes as the VH4 is...

Thanks JohnRageOn... These look really good. So, before I buy a full set of thse Tung Sols can you just clarify this for me? If I buy 7 of these and switch them all in my VH4 that will be ok right? Will the gain be affected much? I read in one article that the gain is lower in these is that...
