I currently have a Tonelab EX pluged in a Peavey 50-50 tube power amp on a Randall 412, I'm pretty sure it's plenty enough for live gig for small to medium venues.

I will acquire a passive mixer for vocals and other effects (laptop mostly), would you think I could use "one side" of the stereo (50W @Valve) and plug a pair of passive speaker on this and this would be loud enough or am I going to be "short" and look for active speaker instead?

Thanks!

If you don't care to sound good to everybody in the audience (if the place can hold more than 30 people or so) then you might well do that.

If you do care for sounding good to a whole audience get a proper, half decent PA system and run everything through it - guitar, voice and whatever else you might have there.

I'm talking about the size of a bar audience. I've seen more than one band play with non-micked 412 for guitars and it sounded good everywhere. I can understand the need for more "power" on the PA, but wouldn't you think the 412 with a 50W Vavle power would be more than enough for a show in a bar, on a stage?

You don't undestand:

The Peavey Classic 50-50 si either stereo 50W per side or one side, bridged mono @ 100W

I would take one channel for my guitar
Guitar > FX and ToneLab > 1 channel 50W > 412

And another channel for the vocal/laptop
Mic / Laptop > Console > 1 Channel 50w > a pair of Passive PA speakers

My quesiton is, would 50W valve be enough

50w RMS would be enough volume wise, the dispersion patterns of your speakers are the problem.

Though if you're convinced a band can sound good with an unmic'd cab in a bar that holds more than 30 or so people then the reputation is yours to loose.

The PA isn't about making the sound loud enough for the bar to hear it so much as for controlling the mix and getting the sound from a single source. If everyone in a full band is on stage cranking the amps so they can be heard, it's going to sound awful to anyone in the bar and you can forget about hearing any drums.
It's different if it's just you and a drummer with a small kit or something like that.

Without a stage monitor of some kind, you can forget about singing well, too. You need to be able to hear yourself clearly.

If it were my gig I'd:

Leave the 412 home, rent a 1/2 decent PA and run the Tonelab direct to the board. With only 2 PA speakers you can angle them inwards to serve as both FOH and side fill monitors. Done this many times in a pinch with good results.

Perfect. You should do this. maybe try to get a floor monitor to point back at yourself?
