If I was going to give some advice ...... it would be to join the PedalPCB forum like was already mentioned ....
you can learn a shit ton from checking out other people's builds ... trouble shooting etc .
The boards they have for sale are top notch .... and I still will occasionally use their boards for a one off project .
Aion effects has maybe 1/4 of the boards ..... but also top notch stuff ...
Pedal PCB doesn't fill in as many " blanks " in the Build Docs as Aion does though .... the build docs on Aion's site are over the top great .
There is some cool stuff over at Madbean Pedals also
As far as your first pedal build ...... I personally wouldn't be looking to do a two in one right away .... it's going to give you some lay out issues to deal with as well as switching .......... and just a heads up ... the Klon's Footswitch varies from a normal True By pass footswitch setup .
I would build the pedals separate ..... then just run them into each other on your board . Especially if you plan to use a " Klon " circuit .... it's probably the best pedal to stack with because of the way the clean signal runs parallel with the overdiven one .... so you're going to want to try other drives in front of it ...trust me
but that's me ................. I hate giving advice on anything on here ..... I don't know your experience .... I know you mentioned you know how to solder which is great ... but there's a lot more to it than that if you want the pedal to sound and look decent .
