I built a few phasers, the Phase II is probably my favorite, i really like how the sweep sounds.
However, i built an other one sometimes ago, a Small Stone clone with all the popular mods, called the Redshift from Aion.
The mods are allowing some interesting sounds, and i often regret that they aren't available on the Phase II.
The most interesting mods are All Pass/Low Pass, Vibrato and 2 stages mods.
I wonder if it could be possible to implement them on the Phase II circuit ?
LDR1 to LDR6, are these the stages ? Do we have 6 stages on this phaser? Would it be possible to add a 2/4/6 stages selector with a 3PDT toggleswitch ?
Surely the Vibrato mod shouldn't be too hard, we just need to cut the original signal and keep only the modulated one, but even such a simple modification is a bit beyond my knowledge in electronics.
Is it as simple as lifting a connection with an SPDT toggle somewhere between C15 and IC5 pin5 ?
When Phase II Feedback is fully CW, is it similar to a vibrato mod ?
About the Low Pass mod, on the Redshift it looks like the switch is connected to some extra caps (C7, C8, C9), or to VB. I guess VB is some special voltage, created in the power section ?
How would you do it ? Is it even possible to do these three mods on PPCB Phase II ?
Every suggestions and observations are welcome !
