Nah, I didn't notice any. I love it. Only took 30 secs to move the wire on the VH4 and it's easily reversable. I've not had any issues since changing it.
Maybe @Leo Diezel could comment on whether it's detrimental or ok?
@Leo Diezel i know you you guys opposes in doing any modifications... but i see few of the highpass filter capacitors soldered on some resistors on the Diezel MK2... if i didnt wanna touch the NFB is there any HPF caps i can remove on the board like making the mids more marshally ? hehe..
