To further Tvad's point, you need to 1st ask yourself
* why are you wanting to modify your equipment? i.e. what is wrong w/ it? or, what is deficient?
* when the equipment is modified, what do you expect to achieve sonically? (this is of course related to the question above).
* if the piece of gear is flawed, is it flawed sufficiently, is it better for you to sell it off & get a better model or switch to another manuf?
You can search the archives here & you'll find many names of modification houses depending which piece of gear you are interested in. Read their comments & find out what they think of the overall experience.
