Switchable Hi-Z input impedance, how ?

[tinitus]

for now, I think the input/muting switch will work like this

[tinitus]

only problem with above input scheme is, tuner isnt working while playing

my main problem seems to be that I insist on the middle POS-2 to be the muting mode
I cant see how, and its very annoying

and btw, the muting mode would actually be the tuner in muting mode
in reality its just a second 'direct out' plug
should be easy, but.....

hey, while thinking about it, a few pictures

I managed to assemble the front
havent yet used the new smoked poly plate
so this is just some scatched clear poly, for the proto work

[tinitus]

ok, regarding input switch toggle postions, I decided to change it
normal playing have to be the middle position
while playing you have both tuner positions available
tuning while playing, and silent tuning
funny how easy it suddenly becomes


I call it audible tuning and silent tuning, because thats how I will use it
but preamp bypass would probably be more correct

Thanks for posting pictures, seems to be progressing well.

less frustrated when I wake up in the morning

looking at the effects loop
right before the tone control curcuit might be a good place

maybe the loop swithc could also do tone bypass
but might be streching a bit too far but its tempting

[tinitus]

and possible front layout
getting crowded, but still doable, thanks to the LED's

if loop/bypass and tone bypass should be done with one and the same switch, then tone bypass will only work when effects loop is in bypass(off) mode
there is only 3 positions possible
but would be perfectly ok as there is no clean signal with effects anyway
hope that makes sense
now I only have to put it together, and make it work

Hi Tinitus, don't worry too much on the switching as there are a lot of permutations. Just suggestion, but I would work on getting all the sections running with very basic switching for now, then you can see what works best and rewire the switches if needed.

absolutely
I know the effect loop will work
having tone bypass in the same switch probably wont
and I dont think I would throw in an exstra switch just for that
tone bypass is not that important
but a few filters could be....shoot, I forgot
ok, I have put in a couple more switches for the tone curcuit, to prepare for any filters no more space for any further crazy ideas
I think design process is finished now

Time to make some music!!
