Intriguingly - so just after EXH revealed its 50th Anniversary Small Stone, MXR now has its own 50th Anniversary Phase 90 - while I’m not aware the latter comes in a wooden box! - which you seem to pay around $100 extra for - for the EHX Model - that and an additional Color Slider Switch and of course original Chip. The Small Stone 50A being sold for $300, where this Gold Phase 90 will be at $199 and equivalent.
Supposedly these are officially out in March - and so will be available for pre-orders soon.
This is the same old One-Knob 4-Stage Phase-Shifter that everyone knows and loves - seemingly just in a different, but admittedly vastly more attractive shiny gold enclosure!
I see this once more as collectible ’shelf-ware’ - and the scalpers will no doubt be out in force again. I’m tempted to get one - but these aren’t really practically usable if you want to maintain the shiny glimmer of the enclosure - most of these won’t find their way onto a Pedalboard - but still more likely than the $300 Small Stone - albeit that format of finish is slightly more practical - but it’s pricing makes it prohibitive.
You can read more about this edition on the MXR Website - I would normally reference the manual too - but it’s not really necessary for this pedal - where just the one knobs controls the Rate and Intensity of the effect!
There’s no official demo or launch video yet, and so I’m referencing a former overview of all the different Phase 90 variants, as below :
