Hello, however overkill it might seem to some, im considering building a Calrec pq1549 in pedal format.
I can read the schematic, draw the pcb, build it etc. but im lacking in the theory/actual circuit knowlegde department, can/will someone direct/help me figure out how to tailor a correct/functional impedance input/output for guitar. Thanks, i hope.

Overkill isn't a word that gets used around here much :o

I'm of no help but am watching this to see what happens!

How loud is too loud?  What?

Just put a voltage follower/buffer in front. Output is fine as is.

TFZ, thanks, i kept digging after i posted, found the PQ1549 as a project here http://www.gyraf.dk/gy_pd/calreq/calrec.htm, they added a balanced input (and output) so i figured it a vf/buffer would do it, its just... sometimes "it cant be that simple" kicks in = lack of knowlegde. Ive gotten to a point where i obviously cant keep on paint by numbers.
Thanks.
