Keep in mind that an Ampeg V-4B is not a smaller/lighter version of an SVT. The V-4Bs are brighter and tighter and some ways more aggressive. But sound fantastic loud and the power tubes compress. Wonderful. Also very loud even for 100w. (But we are talkign tube watts after all.

) Dial them back a little and the make a pretty decent guitar amp.
When I tried the second head at Music-go-round in years ago that was the sound I wanted and been searching for.
This V-4B Classic is the only V-4B (100w) that goes in the SVT direction.

What I play through every week. Same head as above. Sold the one on top. These have the same pre as SVTs, but obviously different power sections.

This is in the front room. Different sounding amp that those above.

I can't see ever getting rid of the V-4BH though I could use the ABM 300 and be happy. But the V-4B I could see selling at some point since I often use the ABM 500 at home. I will say the V-4B heads may be the best looking to my eyes.
