[sdiy] guitar effects (small stone Electro Harmonix) vs synthesizers

[mailing gigaspeeds]

Hi all,

Lately I bought the most recent version of the Small Stone electro Harmonix.
It's intended as a guitar effect and I notice a drop in volume/amplitude 
when connecting my synthesizers to it. Can that be solved ?

What irritates me the most (and makes it totally useless for live 
performance) is that when I hit the enable button (footswitch) I get 
this spike in my speakers that nearly causes  my eadrums to pop :-p.
Is there a way to buffer that spike so I don't hear it when I enable the 
effect ?

I opened it up out of curiosity... there are 4-5 ic's in there, half of 
them were not seated all the way (Made in USA though...) .

Besides that it's a fine effect once enabled :-D


Help would be appreciated !
