Can anyone compare/contrast the TH500 and V4(B)?
Also, master volume vs non on the V4? Are the sensitivity switches enough control that it's not a big deal without the master or is the master a must? |

Ok, one more question that I can't for the life of me find an answer for searching here or the V4 site...
What are the bass and treble eq points on a 70's V4B? I know the V4BH is 40Hz and 4kHz. Same for the original?

The 2 channels sound different.
I can either use one channel at a time (turn one volume all the way down)
OR
I can use both at the same time. The sound is different. |

You just have to try it. the cable is like 8 bucks

As Corey stated then in the post below, "both inputs are going to the same preamp. The only difference is each one has it's own volume control/gain tube".
Bridging the inputs with a Y cable gives you a tiny increase in gain, and allows you to blend the tones of two different preamp tubes if you wish. Other than that, using both inputs simultaneously with the same instrument is not dramatic IMHE. Quote: |

I did notice when I had my V4 that one channel was louder than the other, but as they have separate tubes driving their gain and I put a NOS tube in one and not in the other (that and it was around 40 years old) it's not too surprising there was a little variance.

To each their own, but I didn't see much for combining two channels with the same input. It was useful when I was running an A/B/Y clean-dirty set up though. |

Groovy Gravy, I hope you don't mind me using a picture of your V4B in the thread. If so, let me know and I'll edit my post and use a different picture from somewhere.

With the 2 ohm capability, I'm tempted to get a second

| | Registered User | | Join Date: Aug 2010 Location: Burbank, Ca | | | see how it sounds first before making any decisions! Though Im sure it will sound good, people have mentioned putting deltalites in the v4 cabs with good results. I may be moving up to SF again at the end of january (lived there 3 years in outer sunset), wouldn't mind letting you test out my 15s if I am up there. Though seattle is on the table too, and austin..... | | Thread Tools | Search this Thread | | | |
