I used to not like modulation effects too much, only tremolo. But the years went by and I already had Uni-Vibe kind of pedal on my pedalboard, then Leslie simulator. Then flanger. And then I was looking for phaser and then I noticed one other really cool?. You get the point, my pedalboard was already too full and too big. I have to mention that I play only vintage style tube amps and use analog-effects (except delay).
As I was looking around for other possibilities and was interested to check digital effects development (I haven't used digital guitar gear for ages), I came across Strymon. The need for access to all kinds of modulation effects was pretty urgent and just ordered it after looking some demos on the internet, which did impress me quite a bit.
And I have to admit that Mobius is excatly as Strymon promises it to be. It does not sound like somekind on effect put on top of guitar signal. It really becomes a part of the guitar sound. The tremolo can oscillate in very smoothly or all the opposite, it's possible to make it totally chopping at almost any rate. Leslie simulator is outstanding, vibe is excactly as you expect it to be. So are flanger, chorus, phaser etc. Plus (!) with expression pedal you can control every effect's parameters that you would like. And you even can have it as wah-wah. The wah-wah isn't close to real vintage CryBaby/Vox (but then again, what is), but on some gigs the wah-wah does the trick. Especially the autowah for some songs. The are some cool/funny effects to mess around, but check the demo by Strymon.
And the best of all, you can save your settings. You can switch them quite easily. And of course it has tap function.
As I already have written too much and I still have not covered all the possibilities, the Strymon is heavily recommended. It is pricey, but well? would you like to buy all these quality effects separately?
