POD MULE

[Reeltarded]

Yep. A really good addition would be a simple 6 position rotary with 5 caps and a bypass for the bright.

NULL, 100p, 250p, 500p,1kp, 5kp, something like that? Also NFB lift and the simple resonance 4700p over a 1M. Very little work for lots of shaping. Like $15 worth of parts.

It will rock anyhow. If he has a situation where he can really drive the power, your buddy is gonna love you. I like a POD into tubes when the tubes are about to melt. Way more tones than a Herzog. heh

I've recently wondered how feasible it is to bypass the first gain stage and run the signal into the 1 Meg drive pot through the first .022 capacitor. Why, to get the cathode follower compression and distortion...

Would that work? (schematic above)

So just kill one stage? Drop the input right on the grid of the new first stage.

I think it's the wrong thing to do. The last thing I want there is more gain and something changing bandwidth, but yeah.. no need for that coupler, if I am understanding you.

The power I have used was a pair of 25w amps with no controls. The POD output was the master. Plugged into the returns and took the volume up until the tubes did that thing like a mirage where the glass exists only in a quantum state and you could heat a burrito in less than 60 seconds. Hammered.

Without effects loop.

Thanks Mark. That's the 100w version of how I envisioned to the input into the power amp but was unsure about need for ground reference or grid stopper or coupling capacitor.

It depends if your friend want a full tube amp, or just to add some tube flavour to the output keeping the weight under control.

You can use a 12ax7 as a preamp (stage baxandall stage) going into a source follower then to a class D power amp. Few kilograms, and can easily fit into a 1RU together with the POD. Want to run it stereo? No problem.

All of these things generally sound better through a Marshall; give him a full pre amp / tone stack.
Add Reeltarded's rotary bright switch etc and he'll probably think it's better without the Pod.

I think most, if not all of the PODs are stereo output. You should really consider a two channel power amp. The time based effects are pretty flat without the stereo and the sound won't measure up to the headphones or direct output.

Edit: I don't think there is any need to overdrive the power amp. It rounds off enough rough edges when running clean.
