Here's the Chromatic pitch effect from Cathedral which does the heavy lifting. Choose a Fender clean amp from your collection. Pop your Chromatic pitch effect into a slot 1-4, . Set Voice 1 -12, voice 2 +12, experiment with the 'chords' Put some chorus [chef's kiss Ruppert !!] some reverb after it.
Stick to single strings or 2 note chords to avoid warbling.
Reading the above posts made me dig out mighty Hog2.
Yes. They're expensive (buy a used one).
Yes, Like alot of EHX digital pedals they are very 'digital noise to ground if you don't isolate them.
Yes, its huge. The downside is that they come with a terrible EXP pedal, which you need to swap out for literally anything else.
I've had the Hog - which is 90% as good as the Hog2. The Pog is probably just as good for the job at hand here. But its great at making FAT sounds, organ sounds, celeste. 12 string, bass, flute/piccolo, delicate angelic voices, demonic wails, its a whammy (add a decent EXP pedal), its a wah (exp pedal and the filter section), its Boss Slow Gear (envelope section). Its got great tracking, stores presets, and did I mention its huge ?
NB - if you do get one. Make sure the filter section has Freq all the way up, and Resonance all the way down, other wise you'll think its broken.
NB. If you have access to a Helix - I have 'poormans organ' and 'bigger organ on Line 6's CustomTone. And 'Celestial Menace' which uses dynamics to swap tween lower and higher registers and a Xenomorph fuzz to spoil your neighbours day.
