Harp Amp Mods

Hello Skip
What amp mods would you typically make to a Champ style tube guitar amp to make it more harp friendly? A couiple things I've read about are disabliing the negative feedback circuit, putting in a lower gain pre-amp tube and changing the coupling capacitors to .1uf from .022. Would you make those changes, other changes, or just leave it alone? Thanks!

Thanks Skip. I like the
Thanks Skip. I like the podcast idea... that way you can poke some fun at it!
H-
Disabling the inverse feedback will make it louder, brighter, and more feedback-prone.
Lower-gain preamp tubes are easily reversible and worth a try.
I don't think changing coupling cap values will do much.
I usually change the tone circuit a bit so that it rolls off more highs.
If you send this to Jason (Truth About Vintage Amps podcast) we could tackle it in more depth on the podcast. Or, just call me!
