What do you like to dirty up a keyboard sound?

Specifically, what's a good way to dirty up a digital synth/sampler's inevitable Rhodes, Hammond, or Wurtlitzer sound?  These conditions seem reasonable: you have a fairly full-fidelity amp setup, probably with a tweeter. Or you are going thru the house PA and/or monitors.  This offers you a better reproduction of your piano or strings sound than a fender guitar amp. But what about the vintage electronic keyboard sounds? 
Let me know what you think, but I would imagine a very slight amount of dirt - perhaps the gain or clipping would be adjustable all the way to clean.  In terms of cap values, I would think you don't want to lose low end - no?  High end rolloff too.  Maybe two stacked fetzers? Tube screamer? Anybody try something like this?

Amp/cab sim. Vintage keys often went into guitar amps.  Keyboard amps did exist way back, but were based on existing guitar amps and speakers were guitar type.

It's been a while, but I remember trying all kinds of stomps with my ole Mark I - with mixed results, of course. Best bet always was my bass player's Ampeg with heavy EQing. I guess a decent "dirty" buffer would do the trick, too.

Didn't Jon Lord plug into various Marshall's over the years to get that classic growl?

Nora Jones uses a screamer type pedal on the Wurly. IIRC

My buddy uses a Fairfield Barbershop clone I built him with a sweepable LPF. Sounds real vintage gritty goodness.

A Rhodes through a Twin Reverb is divine.  Analog synths also sound great through tube amps.  Never tried a digital keyboard, but it has to help some.

stomps for keys can be hit and miss. i'd say try a few of your guitarist friends pedals and see what you like... though i'd imagine a tube screamer for a 'soft clipping' sound or a ds-1 for a 'hard clipping' sound would be 2 good 'basic' designs that cover alot of ground...
Actually for going into a pa (full frequency) setup , the tech 21 blonde and their other amp sim pedals are made for that, as are the more economical joyo 'american' or british etc clones of them... they have built in cab sims and pretty flexible eq. can't imagine you couldn't dial in a sound that would work with any of those, and they're really versitile full clean to very dirty  as well as very eq flexible... get a joyo. by all accounts the different ones arent very different and can each get pretty dang close to each other.. the american or the british would be good choices, the california is supposed to have a darker tone so i might stay away from that one.. .
