for a start, just to get an idea of how this switch works
so far only half of it used
and not yet right either

wow, I think switch works

position 1 and 2, all curcuits active
position 3, tube bypass, direct to tone curcuit with tube output muted
tone curcuit can be bypassed fast easy in all positions, having its own tone defeat switch

pole 11 does LED duty
and pole 5 is still free

well, might have nice to switch output
could be a tube direct out option
but havent figured that out yet

yep, not 100% sure yet, but this might work

it should give 3 switch options, one with tube direct out, one with curcuits active, and one with tube bypass

shoot, small error on tube direct out
though, tone output is cut, its input is still connected tube out
not sure thats good

pretty certain this simpler switching layout will work ok
its now only tube bypass, thats all
true bypass, cutting both input and output, ofcourse

the 'reward' of making it simpler would be more switch options left to do a bigger LEDs lightshow :D might be fun :rolleyes:

not sure I will need a tone bypass at all :scratch:

actually, for this one, a simpler ON/OFF/ON switch might be even better, leaving OFF position for muting

but there is still one option I will look at
with a second output plug on back panel, it might be very simple to do a 'direct out' from input buffer
or a more advanced version of this could be used for effects loop
but that option might still need a secondary effect loop switch on back panel

no, no, no
I will not have effects option
connect other 'strange' curcuits, and this whole project would become more or less pointless

would rather 'waste time'on adding that exstra tube direct out switch I previously gave up on

a 'fast switch' for tuner have been considered
but I reckon most tuners are switched on by the instrument jack/plug connection
means it would be permanently 'on', even at preamp power off
would make battery operation completely pointless
and a tuner especially is the only device I would ever use on battery supply

hmm, about the tuner
mighty actually be very practical to have a paralel output, just for tuning
wont even need a switch or anything
just a second plug in paralel with instrument high-z input
makes sense

instrument jack wouldnt have to be pulled
just plug in the tuner to the second plug
tuning while playing would be easy

in light of that, maybe think twice about where to place the muting cut
both audible and silent tuning should be possible

ok, back to .... well

with the added input switch, I will once again try to look at handling each channel seperately
meaning it will be possible to connect different effects to each channel seperately
and each channel will have its own bypass option

muting is a multiple hybrid solution
it either 'kills' both channels
or its optional signal out
for a tuner, or...

well, dont expect too much :D
