Does anyone have any ideas as to how to modify the classic pignose (7-100) so that a clean tone can be obtained at full volume?

Specifically, my goal is to use the amp to accentuate the volume (without distortion) of a washtub bass in live settings. I have already ordered a "replacement" speaker that can handle tones as low as 20hz, but am wondering if I need to replace the volume pot and/or capaciters as well.

Your help or advice would be greatly appreciated.


Thanks!

p.s. I'm really dead set on using the 7-100 model rather than the Hog30, due to portability issues.
