This modification will void the Boss warrantee.
We will warrantee the kill switch.
The kill switch does not make the pedal less reliable and cannot damage the chips.
But if the delay dies, the digital chips cannot be changed and a new board usually needs to be installed. This costs much more than we charge for the mod so we can't install a new board at no charge if your delay dies. You will have to pay to have someone repair it (I will refer you to our repairman in TX).
So be careful and only use a known good 9Vdc power supply so as not to kill this pedal.
Here are some clips from Doug Doppler
which will be on his GET KILLER TONE dvd series. These were meant as demos of the
dirt pedals but you can get an idea of the delay sounds too.
First is a Les Paul into our ASTRO TONE FUZZ
into our Boss DD3 HIGHCUT mod, into a 1963 Fender Vibrasonic. Hendrix-esque Neck Position :
This one is the same setup, Classic Rock Bridge Position...
Here is another one, Tele into an OD pedal into the DD3 mod into a Matchless amp.
