Long story short some factory defective tubes wounded my VH4. So I took the amp to Yontz (Mad Science Amps) here in Raleigh and he, Peter and Laura diagnosed the issue and Peter sent a midi chip from Germany, Laura sent new tubes and Yontz did his magic and I got the amp back today. With new tubes and professionally biased it sounds better then ever. I've been rockin it through my Uberkab. Wow just massive and endless useful tone.
Anyway, just wanted to shout out to these guys for a great job.
