Ampeg V4 vs V4B

[TheRhealDeal]

Can anyone help me understand the difference between these 2 heads?

I have been wanting to get a V4 to go with my Ampeg V9 for some time but I want to make sure I'm getting the right thing.

Thanks!

That's the only difference? That the v4 has a reverb knob and the other doesn't?

What about master volume vs no master volume control? Is this a variation of the same amp?

V4B


Different eras but you get the point. The VT22 is basically a combo version of the V4.

Master volume was added to the post-1975 versions of both. In the late 70s the V4 also got a distortion knob. The V4 has sensitivity switches on the inputs and no bass boost, the V4B lacked the sensitivity switches and had a bass boost. The V4's mid frequency selector was 300/1K/3K, the V4B is 300/800/2.5K. As said above, the V4 also had reverb.

Opps...forgot input sensitivity on the V4.

The bass boost switch acts as a LPF and is almost useless.

Thanks, been a huge help! Any thoughts on which one would work better with my V9? And would 100w be enough to power it you think?

Damn, I use it and love it. Although, I biamp with my cleans (V4B, Ultra low)through a 2x15 and My effects (Peavey VB-2) through a 2x10. No low ends loss from pedals!

hey that particular V4 looks mighty familiar !!!

[77PBass]

I said almost. I read somewhere people used V4B and the bass boost in bi-amped PA situations way back when in the days of Edison.

Agreed. The bass and high boost switches just cut from your mids. I find the normal EQ knobs to be enough for me, but if people like them and that's their thing, that's cool too.

I always preferred the V4 to the V4B back in the day... both had great bottom, but the V4 was able to dial in a little more "bite".
