no word can describe that ....    Good work

Thanks for information.  All I have to do is put the vvr on the power section and make a ppimv ? or the ots already have ppimv ?

I installed a vvr in my ots. All work , good sound in clean. But when in put overdrive on, Isn't the same sound before vvr. I put level and ratio to 10 and my clean channel is louder than overdrive.

How can i have the overdrive back again ?

Put vvr only in my power tube and install ppimv ?

May, i have did something wrong ?

Thanks

That's a good news 

Thanks, I will try  both 

Thanks Gregg but after Read it. I think I will try the hall VVR. VVR has 5 wires and 1 pot to install vs London /w lot of mod and 3 pots  .

I know that at very low level all attenuator don't work well. But I need low lvl like recording at home or small gig, because I have a THD attenuator but it cost me  like 400$ if i can sell it for a London or hallthat cost 50 $ and it can be inside my amp that would be great.

I have a standart OTS 50w and I want to know which is better. I want to have a good sound at low level. I don't able to find some demo on internet. What is good or bad about London vs Hall ?

Where did you install the pot on OTS ?

Thanks 

Sure, i'm interest but I need to hear some demo
