I’m halfway there myself after getting the C4, Spectrum, Ultrawave, and Lunar Phaser. The past two weeks of tweaking have left me with the impression that, given I get a Collider, I can get every sound I need out of Source Audio’s pedals. This is as close to an all-one -brand board as I can get. However, my Korg G5 and Aguilar Octamizer will never leave my board. One a side note...If Source Audio were to ever create/recreate the capabilities of the Yamaha UD Stomp and its 8 delay lines then I would happily be the first to buy it.
