[sdiy] slightly OT: best tube tremolo? table radio amps revisited

[anthony]

This is something I'd usually post to Aron's Stompbox page, but it has been 
changed around and is now unusable for me.

OK so I'm sure some of you read my post about making a guitar amp using a 
really old suicide radio chassis.

SO, then later I found a whole radio all together at a thrift store. It's an 
ugly white Zenith and this one used the 50C5 instead of the 50L6 and I had 
at first thought I'd just use the parts that were there to make an amp like 
the one I'd originally thought of - and this one had an actual speaker in 
it. But then the urge to use one of the sweet vintage Mullard EL84's (that I 
 >found< in my basment a couple of years ago) struck. So I totally gutted the 
whole thing. I even sucked all the solder off - had to use two irons at 
once...

My idea was that this would be a little amp, but I could use it like an 
overdrive pedal too. So I started thinking: it would be even cooler to have 
a tremolo on this too. (Even though I just made a Schaller tremolo clone the 
other day...)

The tremolo designs that I've looked at are the one from the Vox AC4 and a 
couple of the Fenders. It looks like the Fender modulates the power tube 
bias, which seems like a cool idea, but I only see it on push-pull amps.

Is there a big difference in sound betwen the Vox and Fender Tremolos? I 
like tremolos that sound more like a throb rather than a lazy roller 
coaster. (I have yet to find a decent VST tremolo plug-in. Well the 
Amplitube one is pretty good.)

OR should I just go with a bare-bones straight-up simple AX84 P1 and not 
bother with a tube tremolo?
