Re-Verb v4 - two or one toggle switch?

[rpark71]

Hi,

I recently purchased the TH Custom Effects Re-Reverb (v4) kit from Das Musikding and was just checking through the components and it lists x2 toggle switches in the BOM, but only one was supplied (I've queried this with them). But the drilled enclosure I got supplied with the kit only has one toggle switch hole and I see in the completed pedal photo, it just has the Deep switch. Is the OSC switch an extra modification (but not required), as its on the PCB?

Thanks, Rich
