The Moog pedals are incredibly good quality IMO.
The MF104 delay is great on Keys and has a great deal of control over each function. The delayed signal is very muddy but that is not as much of a disadvantage as I initially thought. It becomes more of an additional texture to your input signal as appose to an independent delay, especially with high feedback.
For me, the best pedal in my set up is the Moog MF-103 Phaser. This thing is f**king amazing!! It can be used with a subtle attitude or dramatically. The phasing sweep has a very wide range and the LFO is very controllable and easy to use creatively. It is also very nice to turn the LFO modulation off and manually sweep the phasing frequency, this sounds fantastic when the phase sweep is controlled via a CV pedal. I also utilise the CV output of my Doepfer Dark Time to control any of the CV features on the pedals e.g. Ring Mod OSC Frequency, Phaser Sweep, Delay time etc. This can give you some really cool results that most pedals would struggle to achieve.
I really sound like a Moog salesman here but despite the high price, I can not fault the pedals. The build quality is exceptional and the 4 in my possession sound incredible
I would certainly recommend any of the initial 4 released if you have the money or find one at a bargain price.
Replicants are like any other machine, they're either a benefit or a hazard. If they're a benefit, its not my problem.
