effect built into guitar question

[icepot]

hi i just saw bloc party a week ago, and the guitarist russel uses a guitar with a built in circuit bent toy... i guess the pickups pick the sound coming from the toy so you hear it throught the speakers. this got me thinking...

now i want to build 3 tone generators (schematic below) and place them on the guitar itself. i dont want to put a speaker into the guitar if i don't have to, i was more thinking of wiring the out's to the guitar out itself... is this as simple as just that? or am i in for a hassle. i'm fairly new to this, i have made this tone generator before with a 1/4 output and it went fine. i just don't know how i should output the sound.

how i see this going, is the 3 tonegenerators, will be put into the guitar (telecaster). i have 3 push button switches S.P.S.T Momentary n/o that i will use to trigger the sounds, and then i have some bipolar red/green l.e.d.s that will light red when the effect is on but no sound, and then light green when there is sound.

im going to be doing something similar, with one of my guitars...probably the talman.

APC right onboard...basically switching guitar from on>>apc (off)
