Someone with some pcb-making skills should whip up a small SnB like board for easy implementation into other projects that could benefit from it. Sort of odd that there are no purchaseable/printable pcb projects other than this, considering the myriad of other small utility boards available from both resellers and open sourced. I'd get a bunch ✌️

Thanks y'all.

It can be used as 2 mono channels by using separate pots though the Add/Mix function will control both channels unless the relays are split.
I also see it as a two input stereo mixer, buffer, gain make-up stage etc.
 
Question for anybody who has built this: does the volume stay constant when blending or is there a boost when the pot is in the middle? (when used with a compressor for example, so phase coherent signals)
 
..that can't compute unless we know how much you compress, i.e. how much signal returns in the "processed" side..
Let me clarify: with both dry and wet signals at the same level, is the 'blending' done with constant gain ? In other words : would the output signal level be the same at 50% of the pot as full dry or wet ?

I ask because I'm using the 'crush n blend' in a schematic but with the pot in the middle it's adding ~6dB.
 
Can anyone who built this confirm if bypass channel only turns pot off and is on mix out 100% wet signal in place of 100% dry? Thank in advance
 
Yes, search the thread. Many posts about how the bypass output is 100% wet.
Look at the schematic and you could decide if you want to mod it to be 100% dry on bypass. Connect k3 to k1 instead of k2
