I get a lot of questions about tube changes in our V13 and V13 gen2 Tube Condensers. That makes sense – vacuum tube swaps are one of the easiest modifications to make in tube gear (provided it’s socketed and you’ve got the right pinout!) In our manual, I recommend the EHX 6072A as an alternative tube flavor for our ‘secret-sauce’ V13 tube. We even provide an extra tube slot in the aluminum case, so you can have that extra tube flavor on hand!
Vanguard family member Kit Nolan recently provided a fantastic example of WHAT happens when you change the tube in a V13. He recorded pretty much an entire song with his matched pair of gen1 Vanguard V13s, with the only difference being the tube. He even matched the outputs by LUFS and provided 48k listening files in the link on his video. Check it out below, and you can listen to Kit’s new tune on Spotify as well!
