are there any other trem/verb pedals like it, besides some Line6 multi fx kind of thing?
None spring to mind. And it's really pretty great. There's that also.
I would pay $150 for a Flint trem, and I paid $300 for a Flint Blue Sky, so having trem and reverb in the same box at $300 was ok by me. And the quality is top notch, excellent pedal.
considering to get all those sounds from other boxes you'd be spending probably twice as much, and they're all in one compact box it's pretty fair.
I personally wouldn't spring for an El Cap or Blue Sky at $300 a piece, but i'd gladly pay $150 for a great sounding tremolo with tap tempo capability, and i'd also gladly pay $150 for a killer sounding reverb- when it's all said and done you're paying about $50 per trem/reverb type, which really isn't that bad
As others have said, $300 is the price point for other Strymons (other than the OB.1 and Timeline), and you get a great trem (that does 3 different sounds) and a great reverb (that also has 3 great modes), for $300, it really is a pretty good deal. It has been pretty much permanently planted to my board. I like that it is versatile enough to get a lot of different sounds but not so versatile that it is complicated to work or requires a ton of tweaking to get a good sound.
